Good afternoon!
Three month ago, 6 Heltun Thermostats obtained.
It placed in each heat zone. Mode of using - control air temperature, and check limitations of floor (water heating system).
Each thermostat connected to controller, controller connected to valves and heating device.
And… all thermostats controlled by VeraPlus.
On board:
Air temperature sensor, floor temperature sensor, humidity sensor and lighting sensor (all of them - in one device)
How it works with Vera:
Not very vell
- Thermostat can support modes: Comfort, Eco, Dry, Manual and Timer. Vera - not
- Secondary sensor not recognised well. (but it can be used in DataMine - it works)
- a lot of Poll requests are lost. I don’t know, why - may be Vera not good, may be Heltun
- Device can support S2 security, Vera not
- OTA supported by device, but Vera…
My task:
Heat my house at night time (when possible). Use night tarif (when possible, do not avoid comfort)
Tariffs:
Day: 6,08₽
Night: 2,25₽
This script - make comforable setting in Home/Night mode
Decrease temperature at Vacation mode and heat house only at night - in Away mode
