Midea addon fan speed high keep on showing as unknown

marinusp · January 7, 2026, 5:29pm

Everytime i set fan speed to HIGH i see unknown fan speen error in the openhab logs

apella12 · January 7, 2026, 6:20pm

Could you put the mideaac binding in debug and try to set the speed? Also is there any fan speed high in the under the thing properties drop-down? Not all devices support all speeds, but high is a default, so is normally ok

Hi,

I did set the debug mode and this error is what I am seeing n the logs

Under the thing there is a HIGH option

Regards

Marinus

?

Unfortunately, there is some variability in Midea ACs, so I need to examine the byte stream in the debug mode (openhab log, not event log) to see what to suggest. Is this a version 3 or version 2 device? Example if you don’t want to post much

Bytes in HEX, decoded and stripped without header: length: 25, data: C00053667F7F003C0000045236000000000000000000ABB68C

Here is two examples

Ok seems fixable but need additional information to be sure and not break something else.

Details: The command for High sets the byte right before the 7F7F to 0x50 (80 in decimal). What happens with most devices is there a response starting with C0. Your device (like one other that was tested) also sends an unsolicited (extra) response starting with A0 with 0x64 (100 in decimal) that is not mapped to HIGH, so returns unknown. What I need to see (and you may already have it) is the debug log starting from ({} == your channel name)

Handling channelUID {} with command HIGH

I’m assuming there is a C0 response before the A0 response and I want to see those bytes. Right now both C0 and A0 update the same channel (Fan Speed)

Use the code fences </> for the logs for easier reading

Ok Have a PR to fix[mideaac] Add Fan Speed Option for Version 3 by apella12 · Pull Request #20065 · openhab/openhab-addons

marinusp · January 14, 2026, 7:15am

You are more than welcome to share the code change you made then I can build it on my side and test.

marinusp · January 14, 2026, 7:21am

I saw your code changes in the code commit. Will pull it sometime and test

apella12 · January 14, 2026, 12:58pm

I thought about testing early on, but had a number of questions, like your version of OH and whether a 5.2 snapshot would work. Also, I modified a test case with your output that returned HIGH.

Anyway, here is the jar that works in my OH5.1.1 test environment. Download, Remove the .txt extension, remove the MideaAC binding from your OH and drop jar in the addons. If there are any issues, I’ll need to look at the debug logs again.

marinusp · January 14, 2026, 1:30pm

I pulled your changes and build the jar on my PC and deployed to openhab. Its seems to work perfectly

Thanks for your assistance on this. Appreciated
