5 months ago Hi @calvind80,
On my S2 Mini I am using pin 33 for the RX port, and pin 34 for the TX port, which I think should work on any S2. I switched the defaults away from this because on the WROOM boards it seems to cause them to boot loop because one those boards hard crash if you try to reconfigure some of the pins.

That's worked fine, thank you. I'd tried pins 37 & 39 before but they weren't working for some reason.
I’m not managing to get a connection to the heat pump when using an S2 Mini into an FTC6.
It gets power OK and I can configure everything via the web interface but turning on diagnostics shows no response to the commands.
Which pins should the TX and RX be using on the S2? It doesn’t have pins 26 & 27 and from looking at the specs the physical PIN numbers don’t seem to map directly to the software pins.
I have tried it with a WROOM32 dev board on pins 26 & 27 and that does work but I’d prefer to use the S2 if possible.
