Midea AC can not change FAN speed in ESPHome 2021.9.2

all2beok commented 3 years ago

The problem

After updating to version 2021.9.2 from 2021.8.2 changing fan speed stopped working on Pioneer WYS 21 seer mini split, but its still working on Pioneer WYS 19 seer mini splits. I have two Pioneer WYS 19 seers AC’s and one WYS 21 SEER AC, the dongle connects via WiFi card with USB jack with ‘cuts’ as on some photos. (https://community-assets.home-assistant.io/original/3X/0/0/00692dcfff4c39b5842f1d14447e8c8363e8a771.jpeg) After the update 19 seers mini splits work just fine, but I cant change fan speed on 21 seer anymore, tried re-flashing with different options, changed dongles - no go. The 21 seer AC has the same board but I think it has a bit different functionality then 19 ones. When I check 21 seer AC logs I see a warning saying that it cant automatically get capabilities, but not sure if its related to the issue with changing FAN speed. I’m wondering if anybody had similar issues after update. Thank you!

Update: Interesting enough, sometimes, not sure what the logic, it allows to set FAN speed to high, but never to low or medium, it goes back to auto after 2 sec

[midea:113]: Failed to get 0xB5 capabilities report. Suggest to disable it in config and manually set your appliance options (I tried turning off autoconf - didnt help)

When changing fan speed on 19 seer ACs I see in the log SET_STATUS request being sent but I dont see it for 21 seer AC:

[12:43:44][D][climate:009]: ‘Bedoom AC’ - Setting [12:43:44][D][climate:022]: Fan: HIGH [12:43:44][D][AirConditioner:105]: Enqueuing a priority SET_STATUS(0x40) request…

When I change fan speed on 21 seer AC it seems its not sending this command:

[13:50:58][D][climate:009]: ‘Living Room AC’ - Setting [13:50:58][D][climate:022]: Fan: HIGH [13:50:58][D][AirConditioner:178]: Enqueuing a GET_STATUS(0x41) request… [13:50:58][D][ApplianceBase:173]: Enqueuing the request… [13:50:58][D][ApplianceBase:075]: Getting and sending a request from the queue…

Update: I flashed manually original firmware created in version 8.2 and turns out it can not change fan speed to low and medium, but works fine when I change it to HIGH now I'm not sure if it was working before I've updated ESPHome and supervisor versions or could it be because I use old firmware with latest ESPhome and supervisor? (I dont think so) See additional log info in log section.

Anything in the logs that might be useful for us?

When changing fan speed on 19 seer ACs I see in the log SET_STATUS request being sent but I dont see it for 21 seer AC:

[12:43:44][D][climate:009]: ‘Bedoom AC’ - Setting
[12:43:44][D][climate:022]: Fan: HIGH
[12:43:44][D][AirConditioner:105]: Enqueuing a priority SET_STATUS(0x40) request…

When I change fan speed on 21 seer AC it seems its not sending this command, but sometimes after several attempts it changes speed to HIGH, looks like some kind of request/response issue.

[13:50:58][D][climate:009]: ‘Living Room AC’ - Setting
[13:50:58][D][climate:022]: Fan: HIGH

[13:50:58][D][ApplianceBase:075]: Getting and sending a request from the queue…

With old firmware something similar is happening when changing speed to low it sends state request to AUTO:

Hey there @dudanov, mind taking a look at this issue as it has been labeled with an integration (midea) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

mikedrawback commented 3 years ago

I'm not able to provide logs at the moment but I just wanted to corroborate that I am seeing the same behavior on my Midea U. Unable to control fan speed

mikedrawback commented 3 years ago

fyi @all2beok I tried uninstalling and reinstalling the addon and that seems to have resolved the issue for me

all2beok commented 3 years ago

@mikedrawback Thanks for your input, unfortunately reinstalling the addon didn't work for me, I think it has something to do with the particular AC model I have, it works fine for my other 2 mini splits.though, probably PCB functionality on that AC a bit different, while LED boards are identical. Glad that you were able to fix your issue. 👍

@all2beok I am running into this with my senville 10kbtu. Were you able to figure naything out?

all2beok commented 1 year ago

I switched to Google Home, I know it's cloud based control, but it allows to use Google Nest thermostat. I bought MrCool USB dongle it works through Cielo app, added it to Google Home and wrote simple YAML scripts in Google Home automations to turn on/off ACs when Nets thermostat starts/stops cooling .
