ESPHome configuration example to read Power Meter via IR TTL (Volkszähler)
I'm using an Wemos D1 Mini and a IR Transmitter, 1k Ohm Transistor and some wires. Used hardware see: https://alkly.de/smart-meter-auslesen-mit-tasmota-esphome/
This configuration works for me with my ED100L Smart Meter from EMH.
If needed change your obis_code accordingly to your Power Meters provided values. To see which obis_code's are sent from your power meter, you can simply set the log level for sml to DEBUG.
