PR: set TE sensor offset #3

Closed kalaws closed 1 year ago

kalaws commented 2 years ago

Could not post a PR, so I’m posting as an issue.

Request is to be able to set the offset of a TE sensor. The use case is to adjust outside temperature upwards temporarily when electricity price is high, or weather forecast suggests sun will be warming house in the immediate future.

Do you know a way to do this using heatpump control panel ?

kalaws commented 2 years ago

Yes, in advanced settings this is possible for a whole range of TE sensors, at least in my firmware. I can confirm where, exactly, a little later this afternoon.

Edit: I mean in the advanced service menu accessed by holding button for 6 seconds.

qix67 commented 2 years ago

Ok. On my control panel, I can adjust TE0-TE7 and TE24.

I will take a look tomorrow to see what command the control panel send.

kalaws commented 2 years ago

Outside temperature is TE0, and correction can be up to + / - 10 C.

kalaws commented 2 years ago

Perhaps a better solution is to adjust input temp at the various outside temps (ie 10, 5, 0, -5, -10, -15)?

qix67 commented 2 years ago

I just push a new version of the library. A new function is added: set_sensor_offset.

Hopefully, most of the code was already in the library, it is a minor change.

I have compiled it without error but I have not tested it because I currently have no webserver to perform OTA update of my ESP8266.

wow, great work!
