Is anyone else having issues with their midea matter supported air conditioners? The fan mode barely works for me. The air conditioner always starts up in ECO mode and I would like to have the fan mode change, but it just spins and doesn’t work. I think it worked once with one of my air conditioners. The other commands work fine. Thoughts?
Delete the device and add it back.
I have 5 devices and all of them have the same issue.

Have you tried deleting one of them and adding it back?
Yes I did.
We could have a look at the driver logs…
You’d have to download the SmartThings CLI and execute the following command:
smartthings edge:drivers:logcat
When it asks you to select a driver, choose Matter Thermostat. Then switch the fan mode in the app and post the output of the CLI here.
How do I change my hub selection? It defaults to my old wifi hub, not the station which manages the matter devices?
Find out the IP address of your hub and then:
smartthings edge:drivers:logcat --hub-address=<IP>
Example:
smartthings edge:drivers:logcat --hub-address=192.168.1.123
Thanks! Here are the logs:

Click on the three dots on the device card → information and post a screenshot.
I want to check if your device supports the FanControl cluster, if the endpoint is correct and if it accepts on as a value.
Weird. What’s the name of the model?
Edit: probably this one:
No compliance document available…
No Matter compliance document available.
Looks like the device only accepts auto, high, medium and low, but not on or off. Matter FanMode enum values include: off (0), low (1), medium (2), high (3), on (4), auto (5) and smart (6).
Login here, select the device, take screenshots from the summary, attributes and commands sections.
I think I found the issue. The driver is very lazy when figuring out the supported fan modes:
-- Thermostat
-- Our thermostat fan mode control is probably not granular enough to handle the supported modes here well
-- definitely meant for actual fans and not HVAC fans
if ib.data.value >= clusters.FanControl.attributes.FanModeSequence.OFF_LOW_MED_HIGH_AUTO and
ib.data.value <= clusters.FanControl.attributes.FanModeSequence.OFF_ON_AUTO then
device:emit_event_for_endpoint(ib.endpoint_id, capabilities.thermostatFanMode.supportedThermostatFanModes(
{capabilities.thermostatFanMode.thermostatFanMode.auto.NAME, capabilities.thermostatFanMode.thermostatFanMode.on.NAME},
{visibility = {displayed = false}}
))
else
device:emit_event_for_endpoint(ib.endpoint_id, capabilities.thermostatFanMode.supportedThermostatFanModes(
{capabilities.thermostatFanMode.thermostatFanMode.on.NAME},
{visibility = {displayed = false}}
))
end
It only knows/handles devices with auto and on or just on. Your device only accepts auto, low, medium, high.

How can we get the driver updated?
Just submitted an issue (bug report) a minute ago.

Thank you all!
Hi, @Wajo357, @Andreas_Roedl
Thank you for providing all of these details. I shared your case with the engineering team and will let you know once I get their feedback.
