VT, shelly and heat pump

[paolostivanin]

Hello,
I have an underfloor water heating system controlled by an interla unit (samsung hydronic) which itself is controlled by an external heat pump unit (samsung). I have one Shelly 1 mini gen4 per electrically-actuated water valve (on/off, no modulation). My house is very well insulated and I have some rooms facing north and some south. I live in northern Italy.

The temp/hum sensors are all sonoff zigbee, and everything is in z2m.

I am now in the process of implementing the logic in HA and I found out about this custom component and it seems good for me because it has some kind of adaptive hysteresis/PID/samrt algo implemented, right?

Questions:

1. I own a heat pump, so the heating cycle should be long-lived and not short-lived as the ones for TRV. How do I tell VT that "I'm using a heat pump, please do your magic with that in mind?"
2. what config parameter should I tune for my specific use case? My main concern is the heat pump going on/off too often, which is not good.

Thanks a lot

Hello,

hysteresis/PID/samrt algo implemented, right?
yes. That is the main purpose. For over_climate VTherm (see below), there is no PID but a self-regulation that force the target temp so that it will be reach by the device. PID/TPI is for over_switch or over_valve VTherm.

For heat pump that are self-regulated, the best choice is the over_climate VTherm. See: https://github.com/jmcollin78/versatile_thermostat/blob/main/documentation/en/over-climate.md and https://github.com/jmcollin78/versatile_thermostat/blob/main/documentation/en/self-regulation.md for more informations.
