Not directly connected with this binding but maybe of interest for other users:
As the Tibber Pulse is using the optical interface to my energy meter, I had to migrate away from the current DSMR solution to a local Pulse-querying solution.
I came up with https://github.com/cribskip/pulse2mqtt/blob/main/pulse2mqtt.py
After setting the pulse up for the webserver to be always enabled, not just for setup, it is possible to query the data the pulse sends to tibber. This python script polls this data, transforms it and publishes it to a local MQTT broker.
Have fun,
Sascha
