However, I'm not seeing these errors when I converted the same code to an ESP32 board... I put it through it's paces with no ACK errors:

That probably means the issue is with software serial indeed. ESP32 has 3 HW serial controllers on all pins (which esphome uses automatically).

However, when using tx_pin GPIO1 and rx_pin GPIO3 on ESP8266, it does use the UART0 hw serial too - weird.

Does anyone figure out the issue using the Wemo Mini board?
