Hi! I have since a few years some esp8266/32 devices running, sending sensor values etc to a custom home automation backend using MQTT. As I don’t have time to continue development of that system, I’m considering switching to Home Assistant.
Problem is that my devices send a compact payload like this:
sp=294.22,pv=297.21,rt=149
First, values are in Kelvin, so I need to subtract 273.15 from them to display values in Celsius.
Second, it’s not JSON, so it’s harder to parse using value_template, if I understand it correctly.
What would you suggest? Is there a way to get this working without too much trouble, or should I just resign and update the sensors to send data in JSON?
