Provide asyncio interface for homeassistant

[rytilahti]

It likely doesn't make sense to convert the whole library to use asyncio, but providing a separate homeassistant-friendly interface could be fairly straightforward to implement.

See home-assistant/developers.home-assistant#1412 and home-assistant/developers.home-assistant#1412 (comment) for best practices.

I just read https://developers.home-assistant.io/docs/network_discovery/ but it is not 100% clear to me what is needed here.
Do I understand correctly that the BLEDevice instances need to be passed from homeassistant to the eq3bt library?

@rytilahti Friendly ping!

Hi @TechHummel, sorry for the delay and thanks for the remainder!

Yeah, my understanding is also that the way to handle this would be by passing the BLEDevice created by homeassistant to this library, use it for the update cycle, toss it, and re-do the same procedure on the next cycle. As that doesn't map nicely to the existing API (performing connect on __enter__), it might make sense to create a very lightweight pure-bleak, asyncio interface separate from the existing ones that wraps the synchronous thermostat.

I created previously home-assistant/core#74864 to modernize the code base, but I'm currently occupied with other things so I have no time to look into that until very late autumn or so...

I am looking into this, but I am currently blocked hbldh/bleak#946. Will let you know about any progress.

Hi! I am hitting the same issue here.... I will start checking out this. Any progress on this?

[TechHummel]

Sadly not! Not sure what's causing the issue!

[antoniomolram]

do you have your implementation working on the latest homeassistant? it seems that they want that you don't use the BleakClient() directly, instead the BLEDevice(). I am quite new with the Bleak library too.

It seems that doings so, home assistant can handle multiple BLE python interfaces (what makes sense).

I can use your package as an standalone application (without Home assistant), but once that I integrate it I can't use the functionality, and now I am trying to learn how to debug it :)

[TechHummel]

No, I don't have a working implementation! I am considering just using a MQTT bridge though!

mm, could me maybe a easier solution for the moment, but is quite unfortunate that after a home assistant update the things stopped working (my wife is quite piss off :P)

It's super easy to downgrade HA via the SSH Plugin, worked great for me at least. Tho it's of course only a temporary fix. Make a full backup and download it, before sending this command to your HA.

ha core update --version 2022.6.7

Hope that helps to make your wife a bit happier again. ;-)

cheers,
