midea-openhab

Rough hack to connect a Midea (or compatible) aircon with Openhab.

Master Branch (via Midea cloud)

This is the master branch, which currently communicates with the a/c via midea cloud. Also check the LAN branch, which communicates directly with the device.

Developed for Python 3.8, but probably works ok with anything later than Python 3.5

Requires requests and sseclient

pip install requests
pip install sseclient

Notes & Known issues:

• Some devices reset to 17°C on occasion, when we refresh data from midea cloud. I believe this is because these devices update their current (inside & outside) temperatures independent of the other settings, and the code doesn't currently understand these "special" updates (and as I don't have a device that does this, it's difficult to fix). If you're having this issue, you can set MIDEA_POLL_FREQ_SECS to something very big (say 60*60*24*365), so it will effectively only poll the midea api once (at startup). Thereafter the 17°C resets should (hopefully) go away. Alternatively, use the LAN branch, which doesn't have this issue.
• Midea cloud is very unreliable, and will regularly drop your connection. The code will try to automatically reconnect when it does, but you might want to wrap it in a loop anyway, e.g.

while true; do python3 main.py; sleep 10; done

• There's a (fairly low) limit on the number of logins you can make (in the order of 20/hour) which you'll possibly hit if you restart this a lot. If you hit it, just wait an hour and try again.
• This is a horrendous ball of shite. Don't use it.
