Already defined a Midea app account. Only a single account is supported for Midea Air Appliances (LAN).

Hi all!
After removing and reinstalling the midea appliance I keep getting the following message when trying to add the integration (HACS installation was successful):
"Already defined a Midea app account. Only a single account is supported for Midea Air Appliances (LAN)."

Unfortunately, due to this I cannot re-add the integration.

Uninstalling and re-installing did also not help.

I would be very grateful for any tips to resolve this issue!

Thx a lot!

I am experiencing the same issue.
I will be removing any left over entities in hopes that will fix this.

Hi!
I fixed this by going through all home assistant config files and removing all traces of Midea Air Appliances (LAN). I found a definition in one of the config files located here: /config/.storage. I'm not 100% sure anymore but it was in one of those: .storage/core.config_entries, .storage/core.device_registry, .storage/core.entity_registry, or .storage/core.restore_state.
After removing the respective lines in those files I could install the integration again.
Hope this helps!

I encountered the same issue while upgrading from 0.8.13 to 0.9.4 today. Here are the files within which I found traces:

/config/.storage/core.config_entries
/config/.storage/core.device_registry
/config/.storage/homeassistant.exposed_entities

Once removed, I could set up the add-on from scratch.

That being said, I needed to enable the switch marked as beta to have my air-conditioner found (despite it having worked for a long time on the old version of the add-on just fine).
