HAVC in MQTT: any suggestion?

Hello everyone!

I’m about to start the development of a software managing my HVAC system. The HW is composed by a RPi integrated with a temperature sensor and a dry contact driven using GPIO; the idea is to substitute my actual offline controller.

Everything is started when I realized that no HVAC integration allows local pooling.

The idea is to develop a service that is taking the responsibility to implement the hard logic (I feel more confident with a compiled program instead of basing everything on HA).

The HA integration would be based on MQTT, so the initial target is to get integrated with HAVC MQTT.

Do you see any showstopper?

It is HVAC not HAVC.

If you are building your own device then mqtt will certainly be the easiest way to integrate with HA.
