Thank you :grin: now to work out how to flash it on and get some :grin::grin:

Do you have orginal fw or tasmota?

5

Just ordered a switch, I’ll try it with one before I go mental replacing them all (where possible). It should be here tomorrow.

Did this work well in the end? Was it hard to install with the capacitor?

I just stumbled upon these new switches and wanted to see if your test worked before I start ordering lots of them! I presume double taps and long taps would also work on the touch pad?

Thanks!

The switch was really easy to install, and the capacitor too, just a few screws and wires no fuss.

As for flashing it, I’ve not managed to get it into flash mode yet so it’s still a work in progress

How did you flash this switch? Does it requires soldering or is there a way to use OTA update (tuya-convert?)?

Use this metod https://www.youtube.com/watch?v=RNQXRko5mPU
Its beter. Solidering cable to R10 its risky.
switches work without a problem.
Only the touch sensitivity could be higher but after that time I don’t mind :slight_smile:
