I’m a newbie, and I’m having difficulty finding the hardware I’m looking for.
I’ve searched on the homeassistant components pages for a wall switch that looks like one of these
The requirements are:
EU Standard
Can be powered by charger ou direct do DC220v
Easy to integrate with homeassistant
Budget friendly
Optional, not very deep, because it won’t go to a wall socket
The scenario is, I have a Sonoff SV controlling central heating, and it seats on top of the kitchen cabinet.
I’d like to be able to start manually the boiler without having to use the smartphone.
One of the wall switches would be pressed and it would be detected by home assistant and it would start the boiler.
In a nutshell the switch just has to say to homeassistant, I was pressed, not looking to have wires to a light bulb or anything else. It would be glued to the wall next to the boiler, since I don’t have any wall sockets available.
Those look like the Sonoff Touch or Sonoff T1 switches which can be re-flashed with Tasmota or ESPHome and then be fully integrated into HomeAsssitant. Most of those cheap wifi switches usually just have an ESP8266 chip in them and can be reflashed.
Thank you
I’ve seen sonoff and they may be an option, but only if I can’t find the same in black.
And the sonoff has cables going out to light devices, does it work without being connected to a light bulb or something else?
also the shelly 2.5 might work. But it might get too bulky and I have the same question about not having anything connected there.
If color is more important than cost, you can try buying one of the black ones and open it up and see if it’s flashable. It probably is, but if the PCB layout isnt directly copied from the sonoff version you’ll have to figure out the flashing procedure without a manual.
It only needs power to function. I have a 2 button T1 without any load (lights) connected to it and it just triggers automations in HA.
One of the pictures looks exactly like something I have (in white, but never mind).
Apparently you need just a "remote’.
These are basically RF remotes in a shape of wall switches.
Not too thick, powered by 2x3.3v lithium battery. I don’t like the fact that they don’t have any backlit when NOT pressed, a bit inconvenient in the dark.
So you will need a RF gateway like this (plus a ESP8622/Arduino of course) to convert a RF signal into HA event or something.
Or you can buy this bundle, connect it in parallel to your Sonoff SV and then control that relay from HA via RF gateway.
Hope it helps.
I am a noob, however if your heating system is already controllable from HA any switch or button will work. As AhmadK mentioned, if you were to use openmqttgateway, you can the use any rf switch to do anything, including tur the boiler on.
I just got one of these swiches ( https://amzn.to/2O432ls and it works a treat!
Hi,
Thank you for your answers.
I don’t know how to reply directly to a quote, but I’ll do my best. Is there a page I can learn the basics? I followed this page https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code to learn some stuff, but it doesn’t teach about with the symbol and every thing.

That’s great to know, it was one of my concerns in buying one

I actually have one of those, they work great.
itzmrdavis2u, I could follow your link
Anyway I’m going with the T1 Sonoff. anyone knows the difference between the US and EU version? I was told that the US version needed larger wall sockets?
