Repurposing of hai temperature sensors


Active Member
Hi, my sample house is wired to a omni pro ii console, that communicates with home assistant via mqtt. The console was installed 20+ years ago and it's beginning to have problems, so I'm thinking of a way to switch to something more up to date.
I figured a way to substitute anything except the temperature sensors I have in every room that are used for heating control. Is there a way to repurpose the same sensors with an Arduino/esp 8266/raspberry? I don't want to rewire everything because they're integrated in my wall switches.
