I would like to share my little “momentary wall switch project” combined with a Xiaomi wireless switch.
The one major issue I kept running in to when trying to add lights into my smart home config was that I have “rvs wall switches” which cost me a lot of money and regular switches don’t work well in flows.
Trying to keep my solutions up to the “acceptance levels” of my wife was really hard, untill now I couldn’t find a momentary switch that would work with my “Merten Schneider” wallswitches.
Now that I’ve found a momentary switch that works, I was contemplating about making it work with homey.
At first I wanted to add a Fibaro Z-wave relais but they are pretty pricey!
Then a collegue showed a youtube clip off someone modifying a Xiaomi Aqara switch, we decided to try this.
I went for a regular round Xiaomi wireless switch because this can also handle a “long push” as a scene trigger.
When disassembling the Xiaomi switch my collegue found that it wasn’t necessary to remove the switch button, he found 2 holes on the pcb which also had switch capabilities therefore leaving the button intact and just adding 2 wires.
The first setup will be a Ikea Trädfri dimable lightbulb combined with the above hooked up to a momentary switch. Making it possible to dim the Trädfri light or turning on multiple light with the flick of a switch!!
More will follow later!
