What it is

daikin_mqtt is my attempt to get Home Assistant integration with Daikin AC units working again after the 2.8.0 firmware update that drastically change the API.

A lot of the code is borrowed from bits and pieces I found on different sites, mainly referenced from the native Daikin Home Assistant integration.

What's next

I'm hoping that at some point the native integration is updated to handle the new code there is no need for this integration anymore. I managed to add most of the functionality I really use. I might make some further improvements as I get time, here is a bit of a wish list in no particular order:

• Fan speed control
• Shutter control
• Energy usage telemetry (this will require more reverse engineering as I have no idea where this is stored)
• Better error handling (e.g. if losing connection with the MQTT broker)

Home Assistant shortcoming

This code relies on the MQTT HVAC Home Assistant integration to work. Some of the other MQTT modules have a configuration setting called expiry_after, which allows that after a set period of time, if no new values are received, that Home Assistant shows the device as offline.
MQTT HVAC doesn't currently have an implementation of such feature, therefore it's not possible if this app is operational or crashed at some point from looking at Home Assistant.
If you enjoy this app and feel like supporting my feature request, I would appreciate it if you could upvote it.

Thank you!
