I recently added a smart thermostat but picked a provider that works completely offline and has a good Home Assistant plugin (Wiser https://www.draytoncontrols.co.uk/products/Smart-Heating/Wiser https://www.draytoncontrols.co.uk/products/Smart-Heating/Wis...). It was recommended to me by people in the trade that Wiser is the "cheap" model, but I'd much rather go for the budget option if it means I can go offline and it still works. Would never touch Nest, Hive, Tado etc, I want this to last longer than any of these companies are willing to provide support. Anyone know of a dumber system that has thermostatic TRVs + per room scheduling? Ideally with an offline screen to administer?
