I have a simple wish, but I prefer leaning on your expertise here.
I have a remote home with two rooms. Since the gasprices are sky-high we decided to warm two rooms seperately with electrical heating devices. I have two Aqara Temperature sensors and I have two Aqara switches all controlled via Zigbee2Mqtt. Works like a charm.
Now I want to have a lovelace card with two thermostate knobs that you can set on a certain temperature.
The logic is handled by NodeRed. What is the best way to get the user input of such ‘fake’ thermostate-knobs to have the node-red logic to decide wether to turn on the heater or not.
I can imagine I use de Next-look-a-like lovelace-card for that and that I somehowe create an entitiy that I adjust with that card. Am I in the right direction?
I would do this tomorrow, but my biggest fear is that HA would hang in the middle of a heating cycle and burn down my house (or turn it into a refrigerator)
You can always make HA alert you if that would happen.
If the thermostat is set too high for too long.
But I’m curious about your heating that can set a house on fire from being on?
Do you have a open campfire in the livingroom you want the thermostat to add logs to?
Wel in these times where everybody is avoiding secure gas-heating and replae it with crapy electrical heaters, it might be a real-life risk, @avd706 is pointing at… But I agree, you can shut it off at a certain treshold.
Well, you might expect that your heater has some form of surge in it that prevents it from setting on fire itself… otherwise you need to replace it by a proper or less cheap one.
