This month  I want to give my opinion on what I consider to be the state of the smart home market and hopefully get to hear yours.

Home automation is in the early stages and creating a smart home today is no easy task.

If you have tried to turn your home into a smart home you will no doubt encountered several problems but the most important one is The lack of standardisation.

  • Does the device you are thinking of buying work with your existing setup?
  • Will you need extras hardware to support it?

Google, Amazon, Apple and many others  recognised this situation and are embarking on a standardisation program called connected Home over IP.

This is the goal of the working group

If the Working Group succeeds with this goal, customers can be confident that their device of choice will work in their home and that they will be able to setup and control it with their preferred system.

Out of this came the matter protocol which is in the early stages of being deployed.

How successful this will be in simplifying smart home creation is not known but I’m sceptical.

A recent article by Stacy on IOT is closer to my thinking. She related an article on 9 verge writers and what they have in their smart home. The article is here.

Suffice to say it wasn’t really pretty.

I feel we are still many years away from the day when you can buy a smart home device,unbox it and within minutes it is recognised on you smart home network and able to interact with existing smart home devices.

Instead we are likely to see islands of smart home devices controlled by their own Apps.

Basically we will get a collection of gadgets.

In fact when you think about it is it really necessary for your robo vac to talk to your smart home at all.

What is the Incentive?

How difficult is it to turn on a light switch or adjust the thermostat?

It’s not really difficult and so why automate it.

That I believe will be the opinion of most people today.

What Do you Think?

I would be interested in hearing your views please use the suggestions page

  • Do you agree or disagree?
  • Is there anything holding you back from making your home smart.

When Things go Wrong


Just when you least expect it and when you really don’t need it something goes wrong with the network.

So what do you do?

Well first you need to try and locate the problem. Sometimes this is  easy and other times not.

But three things that you can do now to make it easier are:

  • Get familiar with basic networking
  • Get familiar with basic troubleshooting
  • Get your network documentation up to date.

If you are new to networking then I would recommend you take a look at the basic home networking course.

Then you need to make sure that you have a network diagram and and know how to login to, and manage the devices on your network. So you need up to date network documentation.

Finally you will need to troubleshoot the problem as explained in home network troubleshooting.

Now you should be ready for when things do go wrong.

Wemo Puts halt on Matter

Having just yesterday published a tutorial on the Matter protocol this article came to my attention.

It seems that Belkin have stopped Matter development and are rethinking their approach to the smart home.

From a personal viewpoint I was shocked when I looked at the Matter specification as it is almost 900 pages long (899 to be exact).

I was tempted at the time to ignore it and wait and see. It seems I’m not the only one to think that way but probably for different reasons.

Anyway it will be interesting to see the take up of Matter, and it is something I will be following going forward.

How to convert your home’s coaxial cable into Ethernet lines

This article I found very Interesting because my own house is wired with coax for TV and didn’t realise that this was possible.

I did look at the costs and what they quote is only true for a single connection point.

The actual adaptors are on the expensive side but they may come down.

Using homeplug adapters is still cheaper.

Here is the article

Here is also a very good article explaining how a MOCA network works

Welcome to the newsletter

One of the networking terms you will come across is network latency. If you are confused by this term or simply would like to learn more about it then see –Network Latency for Beginners

In a recent poll Google Home came second in the poll as the most popular home control system. Although I don’ currently use it myself I had a look at it and ordered a Google home speaker to try it.

If you are worried about network security and I’m sure it will be a problem in the future as more smart home devices are installed then you may want to consider isolating your smart home devices from the rest of your home network. See How to Isolate Your Home Network from Your Smart Home Network.

I’ve mentioned matter before but not thread. Thread is the wireless protocol that sites below matter and a knowledge of it will be required going forward.  I did a little research and I will be creating a tutorial sometime soon .

But these may be of interest if you want to learn more.

Samsung SmartThings hub has been matter certified and will be upgraded soon.

That’s all for now.

A while ago I bought my mother some very inexpensive remote controlled sockets like these

She has a habit of turning her TV and standing lights off at the plug before she goes to bed so I thought it would make it easier.

Anyway after a few months she was still turning them off manually so I installed them in my house as the wife likes lots of table and standing lamps.

I must admit they work great and using a small remote is far easier than doing it from a mobile phone.

Doesn’t work with Alexa , Google home etc but I find them incredibly practical and well worth considering especially if you have elderly relatives.

  1. Hi Steve,
    May I ask you a question?
    I have 8 dashboard switches on my NR-dashboard. Every switch present a value in byte order. So the first switch must send a 1, the next 2, 4, 8. I want to add all the values of these switches to 1 number (0-255). If I unswitch an switch I want to substract that order value from the total. So the value represents the state of these 8 switches. I
    My problem: If i change a switch, how can I scan all those others switches to get the total value?
    Canb you help me? Kind regards

    1. Hi
      You need to store the value of each switch in a context variable and using a function node. You ca also store the sum. When one switch changes just update the sum.
      This may help

      If you are still stuck let me know and I’ll put together a simple flow using inject nodes to simulate the switches.
