The IoT Smarthome Battlefield: – More on the smart home standardisation efforts of Google,Apple etc with a interesting overview of the Zigbee and Thread protocols.
The Smart Home is Too Complicated – Amazon thinks it is still too complex and I agree. However the smart home device market is still growing at a strong rate.
Arduino are introducing a new modular platform targeted as IOT- techcrunch
December
Apple,Google,Amazon and many others are teaming up to develop a new smart home standard.- The verge
Exactly what will be standardised isn’t known but it will be based around the IP protocol.
However my guess would be that it is device registration and commands so that all devices have a standard way of being discovered and a set of standard commands.
I also can’t help wondering if MQTT-SN will be adopted here.
The work is being undertaken by the Zigbee alliance and there is an FAQ here.
Sonoff have added a new basic device that supports Zigbee and not Wi-Fi.- Notenoughtech
Amazon last year also added Zigbee support in the echo plus. Which means it can be used as a home hub for Zigbee devices. –Alexa developer.
So it looks like Zigbee is establishing itself as the home automation Wireless standard.

If you are thinking of wiring your home you may find this video useful. It takes a different approach to most home wiring videos and shows you how to do it without having to do major renovations afterwards.
Although I probably wouldn’t adopt this for an entire house I did use this approach many years ago for connecting my basement to the rest of the house, but that was before homeplug adapters were available.

Good review of he smart home market...link
IKEA have created a new smart home business unit which could see a big increase in smart home offerings.. link
Sonoff have released a new switch called the Sonoff mini which is much smaller than the familiar sonoff basic and more importantly supports DIY mode which lets you use the switch without the Internet
Here is a good video that also shows you how to flash it to Tasmota firmware using OTA upgrade.
The shelly switch is an alternative to sonoff and it supports MQTT without the need for flashing.
It is slightly more expensive that sonoff but even smaller.
Here is a good video that compare the shelly switch to the old Sonoff (not the mini).

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
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.
Rgds
Steve
