@Nca78 Awesome, thanks for the update!

@Nca78 - only 500 pieces That's OK though, they're cheap, I already ordered the 0603 ones, just hoping my soldering skills are going to be enough for that size. Let me know as soon as you decide on the res/cap packages. I have only 0805, but can order something else if needed.
Thanks for keeping me in the loop and hope you will be able to crack that protocol!

@Andrei-Călin-Tătar - can you please explain all of your jumper wires. US version looks differently obviously so it's really hard to figure out what you did there based on just the pictures.

@Andrei-Călin-Tătar - Understood, thanks! Why did you need a new touch sensor, could you reuse the existing one?

@Andrei-Călin-Tătar - How did you solve the problem with the power? I tried powering arduino from the built-in 3V connection, but it only worked to turn the lights on. Once on, I almost couldn't communicate with the arduino anymore (like 1 attempt from 20 would be successful).

@Nca78 - I'm not sure if you've seen this or not, but someone seems to have managed to crack the dimmer protocol in this thread: https://forum.mysensors.org/topic/2775/livolo-glass-panel-touch-light-wall-switch-arduino-433mhz

@Nca78 - Hi! Haven't heard from your for quite some time Any progress with this? Were you able to resolve the poor sensitivity issues?

@Nca78 - great news indeed! So you think it's OK to order the PCBs? Did you fix the bug with the resistor or I should add the ground connection myself before ordering the PCBs?
Did you test it with the dimmable switch by the way?

@Nca78 - great, thanks! I don't mind soldering all of them, just wasn't sure if I needed to buy the specific type/package. Is the voltage regulator (SOT23-3) only necessary if I want to encrypt the messages?

@Nca78 - thanks! I can order the non-dimmable versions, but would prefer to avoid this if possible.
Is it necessary to use EIA3216 package for the tantalum capacitors or is it just something you've had handy and can be replaced with any other package (e.g. 0805 or 1206)?

@Nca78 - great! By the way, will I be able to use it with my dimmable switches (even if I lose the dimming functionality) or do I need the non-dimmable version?
