Diyless Thermostat with Wemos D1 Mini ESP32

[mennodegraaf]

Great project! I would love to make it run on my Diyless Thermostat, which uses a Wemos D1 Mini ESP32. After adjusting the platformio.ini file to use wemos_d1_mini32 it compiles. I have adjusted the pin mapping to use OT_IN_PIN_DEFAULT=21, OT_OUT_PIN_DEFAULT=22 and SENSOR_INDOOR_PIN_DEFAULT=18, which should be correct as I have tested it with https://github.com/diyless/esp32-wifi-thermostat.

I noticed some issues however:

• OpenTherm does not work, it times out, although it is connected and configured correctly
• The DS18B20 temp sensor does not give output
• Settings USE_TELNET=1 does not work at all (exception after startup)

Can you point me in some direction what I can try to get it to work?

I don't know if its important, but just checked whats under the cover and it's ESP-WROOM-32 not D1 Mini.

Please note that this firmware is still being tested. 1.4.0-rc.5.zip

Thanks! Everything works now!
