Recently migrated from ST to Hubitat. Between myself and friends I've installed about a dozen Stelpro Ki Zigbee thermostats for our vacation home. I specifically chose this stat because unlike others, it doesn't force a minimum temp of 5C and offers a true OFF mode.
In our cases, we drain the water when away so it often dips to -5C or colder inside. Before we plan on arriving, we use the stats to preheat to 15C then upon arrival the fireplace takes over.
In the ST driver for the Ki Zigbee stat, there was no problem keeping the stats in OFF mode. But in the Hubitat driver, I notice now that the weather has cooled off, the driver appears to be forcing the mode to HEAT when the temperature drops below 5C. This wastes lots of electricity!
I'm not familar with the driver but it looks like code around lines 77-79 is responsible for this behaviour. For now I commented the whole IF case but I'm hoping Phillipe or others can provide a proper solution to this. Thanks!
