I deleted the device in HA again, stopped home assistant, deleted python cache, restarted HA and added the device again and it seems to work now! I don’t understand what exactly was going wrong and why this has resolved the issue.
I’ll do some further testing.
After reconnecting esp to mqtt, it sends device configs to the broker. When a device is deleted, all known HA configs of device entities are deleted.
When PID/Equitherm was enabled, esp should have sent a new config for the climate entity with new limits. But either this didn’t happen, or HA didn’t update the entity config 
That explains why it has now started working properly! Thanks for the support!
Any chance you may implement an ‘Eco’ mode to set the thermostat to a predefined temperature (like 10 degrees)?
But you can set the temperature between 5 and 30 degrees. What should ECO mode do in your opinion?
I’m referring to the Eco mode like available in Nest Thermostat. With the Eco mode, I can set the temperature with one touch to predefined value (in my case I have set it to 10 degrees). When I’m leaving for a longer period, like on vacation, I set turn on the Eco mode. It then jumps to 10 degrees and turns off the schedules. It remembers the target temperature before doing so, and when I’m back and I turn the eco mode off, the temperature jumps back to the previous target temperature and the schedules are working again.
When I think about it now, I think it’s better to automate this in Home Assistant where the schedules are also automated than in OTGatewat. This eco mode leans more toward the automation than toward regulating the heating. I’m gonna make it in HA.
I’m trying to add a BLE indoor sensor (Xiaomi LYWSD03MMC) but with no luck so far. I suspect it has to do with the MAC address but I’m not sure. Where do I find the correct MAC address for the sensor?
Thanks for the help!
I managed to get the BLE sensor connected by discovering finding its MAC address. For this I used your Wiki and the linked other projects.
The OTG now connects to the BLE sensor. The connection is established (I can see the bluetooth icon on the sensor LCD). The read temperature stays however on 0 degrees (same for the read humidity, it stays on 0%).
Any suggestion how to debug?
Are you using pvvx firmware for the sensor?
No, I’m using the stock firmware, the latest version.
Probably encrypted data there. Try using firmware from pvvx for the sensor.
Thanks. I’ll try.
Can you explain what “Turbo mode” exactly does?
I’m having difficulty keeping the house warm. The problem I’m experiencing is that the temperature in the radiators are pretty low when the turbo mode is off. I hardly succeed get the current room temperature increasing. When I turn the turbo mode on, I get the radiators warm (as I was used to them with Nest) and the target current room temperature start increasing. I notice the Turbo mode turns itself off automatically and I cannot understand why.
