OpenTherm Thermostat firmware v2.2
A new v2.2 is ready to download.
New features
- Equithermic regulation with hysteresis (weather dependent)
- Constant temp regulation with hysteresis (manually controlled boiler temperature)
-
Outside temperature sources
- mqtt/REST
- OneWire (DS18B20)
- OpenTherm (a sensor, connected to the boiler / heat pump)
- diyless (using weatherapi)
- weatherapi (API key required)
- openweathermap (API key required)
- sensors offset config
- room setpoint min/max config
- configurable room setpoint step
- HA sensors for outside temperature sources
Bugfixes
- JSON messages corruption (invalid properties values)
- Thermostat2/3 model name as Thermostat 1 within HA autodiscovery
To use equitermic weather-dependent control you will need to configure your location and select a temperature source
Location is selected using a map and then used to fetch the weather data:
We neither store nor use your location in any purposes except the weather data downloading.
If you're concerned about disclosing your location to the third-party services - you can safely select a point at some distance from your house (few hundreds of meters would not induce a significant error)
If you'd like to use openweathermap or weatherapi services for ambient temperature data - you need to register and obtain their free API token (a long alpha-numerical string),
which should be configured within our thermostat using API key field:
The heating curve configuration is done via a draggable graph, where the horizontal axis represents the outside temperature, and the vertical axis represents the desired boiler/heat pump outlet temperature. You can drag the blue dashed markers to set the desired CH water temperature based on the outside conditions.
