I see, I didn't realize there were M0 chips so insanely cheap.

RE: Cutting the voltage regulator
I agree with @sundberg84 it's much easier to unsolder it than butchering the PCB
Check the video here, not good quality but you will get the point

RE: 💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway
I have few sonoff and I just installed one with this script to replace a dead 433 device. So thank you very much for the script and the tutorial.
Reports of regular wifi connection losses are what kept me away from sonoff until now. Maybe the script could check wifi connection regularly and force a reconnect. Something like in the link below ?
RE: LCD Modules
Advantage is you have dual controllers so you can use different sets of custom chars on the two sides of the board.
You could use it as a display for your weather station, I started to make a MySensors clock project including a temperature sensor. I use a smaller LCD to make a bar graph of temperature history using custom chars but I was pretty limited with the custom chars on a single screen (all were used for the bar graph) and "display real estate" to display temperature for the selected bar.
Here you could use one half to display graph, either one or two (on top of each others) bar graphs with up to 20 points, and still have enough space on the other screen to display additionnal info: numerical value, period displayed, min/max in that period, custom icon, ...
I'll try to dig up to find the circuit and the attached code.
RE: LCD Modules
They have datasheet for both the controller and the module, with pin configuration that seems very similar to the "classic" 16x02 or 20x04 LCD modules.
I think you just need to make an adaptater board from the connector pinout to 2 "FC113" I2C LCD adapters, each connected to a different EN pin, and you're good to go with 2 20x04 I2C LCDs ?
RE: Wall switch enclosure
@Nca78 - If only all sellers were like that! If you ever get anything done with that issue please update us here
I have made a MySensors PCB, waiting for it but Seed managed to slow down my order just enough so that they can finish production and register at DHL before they go on holidays
