Enquiry on 'followMe' functionality and corrections to inside temperature sensor

[rrelande]

Thanks a lot for a very clear library, the data exchange is very clear and highly helpful in understanding the protocol and capabilities.

I am trying to solve the issue of inside air temperature sensor under-evaluation the readings. I get up to 1-2 degrees below the actual room temperature and this is becoming an issue to accurately get a correct value accross a building.

The 'follow me' feature is a way where the IR remote sends the actual temperature readings to AC. This ensures that AC cools according to where the IR Remote is located (ie. near the user).

I've been reviewing every possible temperature data in the UART protocol and there is no obvious such capability.

The feature 'set new Temperature' (position 28 in frame) is indeed a support for old units. I've tested on Midea AC and it indeed updates the setpoint, not the actual inside temperature.

There is somehow promising boolean features:
double temp (undocumented and unclear) feelown (undocumented and unclear) yet as they are boolean, it seems there is no way to send a setStatus which includes a 'follow me'-temperature (at least 5 bits)

I've also checked the latest version of the app (smarthome v1.0.9) and there is no such function either available. The only function seems to be available on the IR remote itself using the IR protocol.

So this post is an inquiry and not an actual issue, goal is rather to understand if other community users have found a way to adjust the temperature readings somehow (inside temperature calibrate function or similar).

Some folks (including me) over at https://github.com/esphome/issues/issues/5862 seem to believe it's likely that "follow me" can be set via UART. We just don't know how. @reneklootwijk , you have done fantastic work with this library. Any chance you could chip in with your opinion? Do you think there's a chance this is possible?

I'm asking because my Midea unit cycles frequently due to the integrated temp sensor fluctuations. When using follow me, it runs much more steady, thus increasing efficiency.

If we discover it's possible on the protocol level, I'd be happy to do the work that is needed to ensure it's possible to do so in HomeAssistant.

I looked into this in the past, but could not find any leads. My units do not support the follow me functionality so I am also not able to experiment.
