Change opentherm.yaml, i assume you use a diyless opentherm board in that case a d1_mini

platform: ESP8266 board: d1_mini

Change new esp32::ArduinoInternalGPIOPin(); To new esphome::esp8266::ESP8266GPIOPin();

And set the right pins

climate:

  • platform: custom lambda: |- auto thermostat_in = new esphome::esp8266::ESP8266GPIOPin(); thermostat_in->set_pin(22); thermostat_in->pin_mode(gpio::FLAG_INPUT); auto thermostat_out = new esphome::esp8266::ESP8266GPIOPin(); thermostat_out->set_pin(21); thermostat_out->pin_mode(gpio::FLAG_OUTPUT); auto boiler_in = new esphome::esp8266::ESP8266GPIOPin(); boiler_in->set_pin(23); boiler_in->pin_mode(gpio::FLAG_INPUT); auto boiler_out = new esphome::esp8266::ESP8266GPIOPin(); boiler_out->set_pin(19);

@hooijschuur there was one more issue for me with pins setup for D1 mini ESP8266 module. You can refer to PR #10

hooijschuur commented 1 year ago

Hoi thanks tried it but i do not get any data. when i use tasmota with opentherm i get set and view temps flame etc. but only for the boiler

The sample config file for esp8266 works in my case: d1 mini board + opentherm slave/master shields from diyless.com. You can try to uncomment lines with debug output in processRequest/processResponse procedures. This can help with troubleshooting.

I got this to work on a D1 mini. Tried a S2 mini (ESP32-S2) before but that did not work for some reason.
