P1 smartmeter (API)

Hi,
will try your app in a few days, next friday my meter will be replaced by a P1 smart meter.
I have built a small circuit to connect the smart-meter to an esp8266 device running tasmota with serial-bridge configured. My hope/goal is to use this setup to push the P1 serial messages via mqtt to Homey, or to my Domoticz server as an alternative.
