1 year ago As it looks, the UART interface cannot send and receive at the same time. If I use two infrared reader - one as a transmitter and one as a receiver, it works and even better with an ESP32 ((az-delivery-devkit-v4)) instead of an ESP8266.
Here is the configuration I use for testing :

I try to check the values with your component, but I do do not receive an data for the different tariffs.
It worked with Tasmota.
