  • ⭐ ⭐ ⭐ 3 Stars – My best recommendation for price and quality
  • ⭐ ⭐ 2 Stars – Great for newbies but not the best in terms of quality
  • ⭐ 1 Star – Ultimate Budget goods, will need some DIY and manual tweaking
  • ❌ 1 Cross – Don’t buy this, this is the total opposite of what I suggest getting.

What Is a Smart Home?

A Smart Home is a collection of technology of which allows your devices to communicate with each other over your local internet connection.

Placing everything you have onto the internet is a daunting yet fascinating thing to do. There’s a lot of benefits to Smart Homes and connecting your devices to your Wi-Fi network.

A Smart home allows you to control everything at the touch of a finger or via a voice-controlled smart speaker, we will tackle that later on in this post once the basics have been explained.

Voice-controlled Smart Speakers are often the main core of your Smart Home as they are often bundled as voice controlled hubs. You may know the common forms of voice assistant which include Amazon Echo, Google Home & Siri.

Smart Homes are great for keeping statistics of your home as well, want to know how many times a light switch is turned on and off a day? You can track that! Want to know how often a door is opened and closed? That can be done too.

This is great for paring with CCTV cameras as you can store timestamps of when specifics triggers are hit.

Personally, I use mine to track my smart meter energy into an excel spreadsheet so I can automatically generate charts of which months use the most electricity and at what times.

One of the better uses of Smart Home Technology is automation via routines, much like in Disney’s Wall-E I like everything being done for me at specific times and having my life organised.

Wall-E Futuristic Smart Home

For example, at 6 am, coffee is made, my lights start to turn on slowly near my desk and my lo-fi playlist starts playing on my Alexa Dot quietly.

How do I do this? Most of this took 5-10 minutes to set up via the Alexa App and IFTTT, there are alternatives to IFTTT but none of them really boast the accessbility and ease of IFTTT.

Note: IFTTT now costs money rather than it’s prior model, many users have moved away from IFTTT due to this.

Ultimate Smart Home Guide / Tutorial For Beginners 2021

Smart Home Technology typically comes in two different forms; Cloud-Based & Localised.

Whilst both have pros and cons, you will find people who swear by only one or the other to improve their quality of life, but how do you know that the method you choose is the most optimised?

Cloud vs Local Controls

The easiest method for setting up a Smart Home is to use cloud based services and let them get on with it. Unfortunately, this means you do need to give up your privacy and there’s no security if the company handling your data closes down.

What is a Locally Controlled Smart Home?

AvaCube Smart Hub

A Local control infrastructure means if your external internet connection goes down, everything internal will still work; your lights, heating, electricity and if you have a local music server, that too!

This is because everything in your house will run through a Smart Hub, like the Samsung SmartThings, Hubitat or Avacube.

What is a Cloud Controlled Smart Home?

A cloud-based infrastructure means everything you request via voice or Smart Device or Button goes directly to a third party (Google, Amazon etc), communicated with their cloud system and then their services send a command back to your devices.

Whilst the majority of these can work as a tool to communicate with your local infrastructure, it rules out the main parts of what makes a real automated home system:

  • Turning off appliances remotely
  • Control online music platforms like Spotify, Amazon Music & Kindle remotely
  • Saving your security footage to an external service
  • Locking and Unlocking your door for your mum who comes round unexpected… Thanks, mum.
  • Checking your indoor and outdoor CCTV Cameras
  • Making sure your coffee is made every morning or by a voice command

What exactly is a Smart Hub?

A Smart Home Hub is the hardware that connects all your individual devices together for home automation purposes via one network. It’s like the brain of your house.

Smart Home Hubs will often connect to a variety are useful for devices which use Zigbee and/or Z-Wave Protocols. You can also use Bluetooth for some of these devices.

Sometimes you’ll find a Smart Hub referred to as a “Bridge“, which basically means it allows different branded devices to all communicate with one another without any issue. Amazon products connecting to Non-Amazon products for example.

Another example is if a smart phone which doesn’t use Zigbee technology wishes to control something which only uses Zigbee, it will need to send that command to a Smart Hub which will then process it for you. Think of it like a translator between technologies.

So, you don’t need a Smart Hub, but it’s definitely recommended that you do get one as it saves you a LOT of hassle in the future. If you’re not sure which Smart Hub to get, I highly suggest

What is the difference between Zigbee and Z-Wave?

Both Zigbee and Z Wave on what is known as a Mesh Network, this means that everything you do is somewhat nested. Like a network in a network where everything all connects to one another.

Time to get technical, Zigbee uses what is called an IEEE 802.15.4 network standard to keep all the Zigbee devices on the network.

Whilst AES 128-bit symmetric encryption is considered better as it keeps all data on the device a little more secure, it could lead to interference with everything else running on the same frequency.

Z Wave on the other had runs 128-bit Symmetric Encryption. Z Wave is slightly ahead of Zigbee in most cases and it experiences less interference with other frequencies.

Smart Lights

Sengled Smart Bulb and Hub

What is the point of smart lights?

Smart lighting is to some, the pinnacle of smart home automation. It provides an efficient and ‘lazy’ way of managing your lighting remotely.

With smart lighting, you’ll be replacing all your traditional bulbs with smart light bulbs. These Wi-Fi controlled bulbs have some great basic benefits:

  • Remotely control your lights around the home without moving out of your seat
  • Schedule automated lighting so that they turn on at certain times or turn all lights off to save electricity
  • The bulbs themselves save a ton on electricity in the long run and have a much longer lifespan than most conventional bulbs.

How long does a smart light bulb last?

Smart LED bulbs typically last between 15,000 – 25,000 hours, but this really depends on the manufacturer. I would suggest avoiding the off-market Chinese bulbs as these will have a lower life expectancy.

The best way to think about this is, if a smart bulb has the minimum lifespan of 15,000 hours and is on for a total of 5 hours, it should last 8 years.

Do Smart Bulbs use electricity when turned off?

This is a genuine concern, technically if you turn off the light via a standard light switch, it ruins the connection to the Smart Hub stopping it from being remotely controlled until turned on.

This can be resolved with Smart Light Switches, but does this mean it uses electricity when ‘off’?

Smart bulbs do use electricity when turned ‘off’, but it’s so minimal it’s not even noticeable. This changes per bulb manufacturer, for Philips Hue bulbs, you’ll find it costs $0.016 per month, which is ridiculously cheap.

Smart Speakers

What is the purpose of a smart speaker?

A Smart Speaker (Also knowns as a Voice Assistant Speaker) is more than just a wireless speaker, it has voice commands and an integrated virtual assistant that offers you a variety of tools and hand-free activation via what is called a “hot word”. For example “Siri”, “Ok, Google”, “Alexa”.

How does a smart speaker work?

A Smart Speaker will continuously have an open mic so that it can constantly listen for a command. Once it has that trigger it will convert what you say to text, send that to their servers which will send a command with data back to your Smart speaker.

How does a Smart Speaker Work Diagram

Smart Speakers are essentially voice assistants with a built in speaker system so you can listen to a response, call other users, listen to music etc.

Are Smart Speakers safe?

It’s worth remembering that Smart Technology is just small computers, so, it is possible that these can technically be hacked/infiltrated. Luckily, if you’re using a popular branded device – Amazon, Google, Samsung and Apple, you’ll find it’s fairly secure.

Each of these devices supports a network connection of WPA-2 encryption, which means that the connection is secured away from the public.

There shouldn’t be that much need to worry about these devices being safe as they are updated very regularly.

There were some concerns about Alexa always listening to what you say, but you can ask Alexa to delete everything now, you can read an article on this here.

Smart Plugs

What can a smart plug do?

Think of a Smart Plug as a dumb appliance converter, it lets you turn on and off appliances from the wall via your trigger device which is great if you have run out of bulbs or want to turn on a fan at certain times of the day in summer.

I use mine on a schedule for turning most appliances off at 1 am, especially my TVs and my Tumble Dryer. Alternatively, if you have a smartwatch or a fitness band, you can simply check if IFTTT integrates and will shut these devices down when you sleep.

Here are some other suggestions:

  • Control TV and console time in your family home
  • Manage external heaters
  • Save Money
  • Switch appliances off when your smart phone isn’t in the Geo location area
  • Use your tech to setup a wake schedule

What is a Smart Home camera?

Home security used to be extremely expensive, but now you no longer need to spend all of your spare money to keep yourself safe. Smart Home Cameras are so much cheaper and have a lot of features, wireless and remote access apps allow you to check your home from wherever you are in the world as long as you have an internet connection.

Wireless Cameras help ensure you, your family and your possessions are fully protected, pair this with Alexa Guard and you have yourself a very secure home! Whether it’s indoors or outdoors.

In the event you are burgled or have a security breach, everything will be recorded in HD and uploaded to the cloud.

Indoor Smart Security Cameras

Indoor wireless cameras are a lot more limited than outdoor ones. However, you can’t beat the quality for the price that a lot of these camera setups are. Keep an eye on all of your possessions and easily tuck the camera away due to how portable they are.

Definitely check out the Neos, Wyze and Blink XT-2 Cameras if you’re looking for indoor cameras!

If you have yourself a smart food dispenser, you can simply check it via your camera and then dispense food for your pet!

Outdoor Smart Security Cameras

Outdoor Cameras tend to be more popular than indoor cameras as they are the first defence against burglars. These cameras tend to be much higher in quality being weather-proof, equipped with night vision & motion sensors. This should really be your go-to before internal smart home cameras.

My personal opinion with outdoor cameras is to go wired rather than wireless. Whilst I’ve never experienced any issues, I have heard on Reddit about security camera being stolen.

What is a smart door lock?

A smart lock is a replacement lock you put into your front door which connects via NFC or Wifi to allow your door to be unlocked when you come home, put your phone against your lock or manually.

Your connection will be encrypted which allows you to authenticate your device, but like any security device like this, there are some precautions you will need to take.

In my opinion the best thing about Smart Locks are the notifications you’ll receive, if your door is opened whilst you’re not on the Wi-Fi connection you will be told which device unlocked it and at what time.

What are the best smart locks?

As of 2019, there is a wide range of Smart Locks, Keys are a thing of the past. Security and identity are the only real way to fully control your home and with these devices, you’ll be able to see which ones I recommend:

All of these except the Yale Smart Lock offer notifications, as such, that’s the reason it only gets the 1 ⭐.

What smart locks work with Alexa?

Obviously compatibility is an issue, I’ve not tested any with my Google Hub, so I’ll need to get back to you on that, however this is the smart locks I know that work with Alexa:

Can smart door locks be hacked?

Smart door locks CAN be hacked, unfortunately, this is just how the technology works, especially devices which utilise Wi-Fi / Bluetooth / NFC technology. Smart locks are operated electronically which as you can imagine will open your lock up to many potential security risks.

One of the main drawbacks is that you’ll need your phone, if your phone is stolen or dead, it can’t connect to the Wi-Fi connection or authorise yourself through the door. If stolen, your door could also be unlocked by the same criminal who stole your phone.

Another major vulnerability is that your smart lock could simply be removed with a Flathead screwdriver. Whilst you’ll be notified in most cases and recorded if you use a front door bell security camera such as Ring.

Some smart locks that have deadlocks need to meet certain specifications before installation, for example, some Smart Locks only work with “Thumb turn deadbolts” and not “double cylinder deadbolts”.

My personal suggestion here is to incorporate the Ring system, with your Smart Lock so you have double the levels of security.

Should I get a smart thermostat?

Smart Thermostats are easy to program, no in-depth guide needed home automation tools for saving money and keeping your house at a decent temperature.

Smart thermostats are so much easier to use than your standard thermostat with all the buttons and manuals with various programmes and waiting to test for it to not work.

One of the more common and best seen Thermostat is the Google Nest Thermostat.

Honestly, just move to a Smart thermostat, your life will be so much easier.

Do smart thermostats really save you money?

A smart thermostat won’t instantly save money by doing some trickery to make it just work, but it does allow you to set up programmes which save you money in the long term.

Nest did a study on this that states that customers saved an average of 10 to 12% on their heating bills and around 15% on air conditioning bills. The great thing here is that it is definitely reputable as there are other independent tests outside of Nest which found similar savings.

Ecobee3 also made some claims on their devices which seem to be a little further ahead than Nest, but I couldn’t find any statistics for this. They claim that they can save you up to 23% on your energy bills if your thermostat is set to a constant temperature of 72 Fahrenheit (22 degrees Celsius) all year.

Obviously this all depends on what you’re doing and how often you’re using your heating, if you have double glazing and how often your windows are open. Here are some tools you can use to see how much you can save:

I Can’t Find A Smart Thermostat That Is Compatible With My System

It’s worth noting that most Smart Thermostats as of right now are very basic in terms of how they can incorporate with other devices, for example, if you have an electric baseboard or electric floor heating, you probably won’t be able to control this directly via a Smart Thermostat.

Personally, I think an Arduino project is likely the better option here as you can use it as a middleman and transfer the data between one device to another.

Smart Light Switches

What is a smart light switch?

A smart light switch is like your standard light switch, except it never has an off state.

Pressing off on the switch will simply dim it till there’s no light but there is still an electrical current.

Adding to this, it’s network-enabled which means you can control it from your smart hub, phone and virtual assistant.

What can a smart light switch do?

Smart light switches are awesome, even if a little expensive, they let you control the devices you allocate in your home via your voice, smartphone app or the wall switch. I use mine to control the lighting in my living room, hallway, bedroom and the backboard on my bed as you can see below:

Here are some of my favourite features of Smart Light Switches:

  • Wi-Fi integration really does make it a smart home
  • Turning switches on and off via your voice is perfect, whether it be Google Assistant or Amazon Alexa. If you have an Apple HomeKit you need to make sure that the switches are compatible as they are quite different in their ecosystem. This applies to HomeKit & Siri separately, so your iPhone may not work either.
  • Setting up schedules and routines via your phone is super easy, regardless of the app. I go with Philips Hue, but you may find some third party ones really help. My lights come on at 7pm and turn off automatically at 1am. Dimming on and off depending on the time of the day.
  • You can group everything up, want to program different scenes? Some Smart Light switches let you do this!

Can you install a smart switch with no neutral?

Yes & No, this really depends on your type of smart light switch. A lot of smart light switches will require a neutral, in fact, most will. There are a few options when you are trying to install a smart light switch and admittedly unless you’re DIY Savvy, it can be a bit of a pain.

If you’re looking for a “No Neutral” solution, you can purchase a module that’ll solve this for you, this is the one I recommend.

If you’re feeling uncomfortable with all this, Philips Hue has come to save the day! They have a magnetic wall switch that you can just slap on your wall and it gets to work. Best of all? It’s super cheap!

Smart Doorbells

How does a wireless video doorbell work?

A smart home wireless video doorbell is very different to your conventional video home recording system, you’ll find these are 99% of the time cloud-based and work with sensors on the camera to send a signal to the server via your Wi-Fi connection and then to your connected devices like your phone.

What are the best wireless doorbells?

This is totally subjective, but I only really have 3 suggestions for the best smart home doorbells and they are:

I’m placing Ring at #1 because their products are pretty damn good in comparison to the others, the only close one there is the BLINK XT, a lot of people go with NEST due to their ecosystem, but I much prefer Ring due to its price and features.

Is there a monthly charge for ring doorbell?

All ring products do have an optional subscription service, this is because they store your videos onto their cloud servers. It’s worth noting this isn’t a requirement, so you will still receive remote notifications when your doorbell is pressed or a motion sensor is triggered.

You’ll still get access to the live streaming element as well, two-way audio so you can see, hear and speak to your guests. If you wish to review the recordings or have the ability to store them locally you will need to upgrade your plan.

There are two options for Ring Video Recording: Basic and Protect. Basic costs $3 per month or $30 for the year per device; Protect costs $10 per month or $100 for year, and it covers an unlimited amount of Ring cameras, offers a lifetime product warranty and gives you an additional 10% off future purchases at Ring.com.

Smoke Detectors

It’s important to have at least one working smoke detector (Or Carbon-Monoxide Detector), But they’re totally pointless if you’re not about when they go off. So having a notification straight to your phone is extremely useful.

Smoke detectors don’t appear to have made great leaps in the last decade, but with Alexa Guard, there has been a middle ground. However, there are dedicated smoke detectors for Smart Homes which are a lot more detailed.

Can Alexa detect a smoke alarm?

With Alexa Guard, you can now get notifications on your phone if your echo device detects the sound of a smoke/carbon monoxide alarm going off. Setting up Alexa Guard is super easy, free and can be paired alongside a smart smoke detector or your normal one.

Does the Nest smoke alarm detect carbon monoxide?

Nest tends to be seen as the best Smoke & Carbon monoxide detector because it’s an all in one solution. It sends alerts to your phone when you’re not home.

Ultimate Smart Home Guide / Tutorial For Beginners 2021

It uses what is called Split-Spectrum sensors to detect fast and slow burning fires which can be turned off remotely via your phone. If you have multiple Nest Carbon Monoxide Detectors, you can simply press the alarm with one tap and you will get a report of all alarms.

Robot Vacuums

Robot Vacuum vs Traditional Vacuum

Robot Vacuums are all the rage now, totally cut a job of the day out and have your pet cleaner leave its charging station, clean and then go back and charge.

But how do they work and how can you incorporate them into your smart home?

Can these devices replace your traditional arm aching vacuum? There is no doubt that a manual job ensures it’s done properly, but with AI and smart technology, smart robot vacuums do a pretty good job, which is much better if done regularly.

Are robot vacuums worth it?

iRobot is the main Robot Vacuum out there, you’ll see the name Roomba thrown around a lot, their prices vary from $300 to $900 which may seem like a lot of money and it may push the Robot Vacuum out of your mind for quite some time. But the future is now and it is clean!

The Robot Vacuum will save you precious time that can be used for your family or activities and hobbies. I set mine to run at 9am every day whilst I’m working as I’m not likely to be up and about and get in its way. Think of how busy you are during the day and how much time you want to spend relaxing when you get home from work?

Saving an hour or two every week adds up, you’ll be saving 416 hours a year which can be spent doing other tasks/jobs or even relaxing.

Security Concerns

Are smart homes safe?

Smart Homes are great, I love them, I love making my life easier. I like not having to do much around my house but that doesn’t mean there aren’t risks.

Anything smart which uses a Wi-Fi connection and has a computer, can technically be hacked/infiltrated, this includes your smart locks, your smoke alarms and even your TV.

Should I put smart devices on guest network?

It’s possible and technically safe as long as it has a password, this means you can keep all standard traffic on one connection and all smart traffic available to anyone who accesses your home and is connected.

Personally, I like to keep full control of smart devices via App, users can connect via a middleman like the Smart Assistant Hubs or a Smart LightSwitch.

Should I put smart devices on an open network?

No. Don’t put anything on a public network that you wish to keep control of, especially if you have devices which connect to third-party tools such as Amazon Alexa.

Jargon buster

Ultimate Smart Home Guide / Tutorial For Beginners 2021

Here are a few terms I think you might like explained, to get you started. Let us know in the comments if there’s anything else you’d like us to cover.

Actions – Pre-set series of smart home controls mapped to one voice command, delivered via Alexa or Google Assistant.

AirPlay – AirPlay is Apple’s protocol – a kind of gadget language – that allows you to transfer audio and video between devices using Wi-Fi.

Bluetooth LE – Another one of those protocols, Bluetooth LE connects devices which are near to each other (e.g. in the same room) once it is activated and they are paired, such as wearables and speakers. The LE stands for low energy as it requires very little power.

Controller – How you control your smart home devices. This could be a smartphone app, a voice powered speaker or a universal remote control.

Geofencing – A virtual fence which can be used to let your devices know you’re close to home, walking in the front door or leaving. It uses GPS or RFID technologies to send an alert when a device, for example your smartphone, crosses a geographic boundary.

Group – When you collect devices together to control them as one group. For example, everything in the bedroom could be switched off with one action such as a voice command or swipe in a phone app

Hub – This one is up for dispute but at its core a smart home hub connects various different devices, which might be compatible with different protocols, and gives you control over everything via one app, voice assistant or screen based system.

HVAC – Easy. Heating, ventilation and air conditioning.

Internet of Things – Also known as IOT, this is the concept of connecting objects to the internet, including smart home devices and sensors but also in industry, business and smart cities etc.

Multi-room audio – One speaker system which can play the same music, from your phone or another media source, in more than room. This used to require drilling and wiring but now works via your Wi-Fi network.

Scene (or Routine) – Getting into home automation, a scene allows you to send more than one command to more than one device. An easy example is a smart lighting scene could have one green, one purple and one yellow light but scenes can also be used across different categories such as ‘Home’, ‘Bed’ and ‘Holiday’. Sometimes has different names.

Sensor – A useful piece of the smart home puzzle, a sensor is anything which can detect or measure change in its surroundings. This could be movement as in a window sensor but also temperature, humidity, air quality, light and noise.

Smart display – This is basically a smart speaker but built around a display. The Echo Show and Google Home Hub are smart displays. Confusingly, Google’s like of smart displays running Android Things are branded Smart Displays, with capitalized S and D.

Voice assistant – The proper name for Alexa or Google Assistant, which are basically interfaces you talk to, rather than use via a screen.

Zigbee and Z-Wave – Two popular smart home protocols. These are a mechanism for different tech devices to communicate, like speaking the same language. Zigbee is known for its speed and low energy use; Z-Wave for its mesh network which boosts Wi-Fi performance. Other protocols include Insteon, X10 and LightwaveRF.
