Monitor and control Daikin/Rotex (hybrid/Altherma) heat pumps via the 2-wire P1/P2 thermostat interface with an ATmega328P, ESP8266, and electronics. The P1P2Serial library and P1P2Monitor program perform low-level bus operation, the P1P2-bridge-esp8266 program interprets data from/to MQTT supporting Home Assistant MQTT discovery.

hc_bridge_v_interface not handled correctly #103

This sensor is flooding my logbook in Home Assistant when the value changes (e.g from 14.7V to 14.8V) It is somehow not handled as a numeric value but more as a string? At least when I click on this entity no graph is showing but only the history (Verlauf)

Thanks for reporting. Which P1P2MQTT-bridge version are you running? V0.9.49 introduced a hysteresis check to reduce the flooding. Only changes of at least 0.2V should be reported now. I'll make the entity a true "voltage" one in the next release so a graph can be made.

In v0.9.53 it is formatted as a voltage. Only the icon is still missing, I didn't yet look for a nice mdi image.
