[Feature request] On-the-edge temperature-dependent relay control: stand alone HVAC/floor-heating control

[gon0]

The NSPanel's temperature sensor is quite noisy and picks up temperature increases from the active display.

However, these issues can probably be tackled:

• the temperature noise can possibly be reduced by https://github.com/NSPManager/NSPanelManager/issues/111
• the temperature offset is already successfully adjustable by https://github.com/NSPManager/NSPanelManager/issues/88
• the display is on for a short time and switched off quickly, reducing the impact on the temperature measurement

With all these issues reduced or resolved, the NSPanel could be used for a stand-alone floor-heating/HVAC control.

I propose that the NSPanel could switch one relay on or off with a hysteresis around a temperature setpoint. So a floor-heating is controlled by the temperature, independently from WiFi/HomeAssistant Server/other control systems.

I could imagine, that the following values could be set from Home Assistant:

• temperature setpoint: relay on (the target temperature, which switches the relay on), e.g. 18 °C
• temperature setpoint: relay off (the target temperature, which switches the relay off), e.g. 20 °C
• time duration for relay change (the duration, how long the actual (mean) temperature value should be below "temperature setpoint: relay on" or above "temperature setpoint: relay off")

Once set, the NSPanel could function as a stand-alone unit (probably not as reliable as other units on the market), but probably one of the cheapest solutions which I would trust to leave the flat for a few days without worrying + internet-controlled heating without costly premium brand solutions with an additional bride like BOSCH..etc.

Sorry for the delay. I though I had answered this but apparently not. This is a very interesting idea and something I will gladly implement as it shouldn't bee to hard though it might take some time until I get to it. Thanks for the suggestion!
