@sjlouw I allways use 32's the older 8266's wifi stack on esphome was allways touch and go. I ended up removing R7 as well as two other resistive sensors I had on the 32. Its now perfectly stable.
Thanks for the effort.
This is by far the best option of getting the data in HomeAssistant on sunsynk inverters!
Thanks for this , this is excellent. The ESP32 method is by far the quickest and easiest.
Only issue I seam to be having is delayed readings, sometime no readings. @sjlouw did you remove the termination resistor (R7) off from the RS485 board? Or do you have similar issues using the esp32
Thanks for the effort
