I have successfully got this working with ESPHome, as described above.

Thanks to the developers :+1:.

Might I suggest a new thread, or a community guide about this installation as I only managed to find it half way down a very long thread about a different installation method, after much reading and confusion.

Shoot ā€¦forgot all about itā€¦still need it?
(or maybe someone else can post their yaml?:thinking:)

251

Could you possibly make a manual, Iā€™m currently despairing with my RPI4, I havenā€™t worked with ESP Home yet :slight_smile:

252

Iā€™ll have a go at this tomorrow.

I have the following problem. I was able to pair my two Bluetooth controls but after some time the status was not available. Can I keep the connection with esp32 active?

254

Could you share it please ?

Iā€™m ESP newbie and also looking for a config to start with.

Not sure I can help with that, having only just got it going, Iā€™ve not had any problems yet.

I would check you phone is not trying to connect.

I would add an uptime sensor to your ESP, to see if its rebooting

text_sensor:
  - platform: uptime
    name: Uptime

I would connect just one AC unit, see if it works then.

257

Can you possibly make an instruction how you have implemented this with EspHome. I have no experience here.

258

I made a community guide here:
https://community.home-assistant.io/t/daikin-madoka-brc1h-bluetooth-with-esphome-via-btproxy/

Please edit and correct where necessary.

Little update here.

Two AC units connected and stable, but I have seen a problem: although order transmission (setting mode, speed, temp) works fast and flawlessly, all the time one of my HA components Will not update and Will be kept outdated: for example, if the initial temperature was set in 25ā°, it Will show that config all the time even if I change It to another value (same applies to modes). The other unit Will be updated.

Looking at the log in ESPHome, I see that updated keep coming in, but packages and values start overflowing the buffer. I Will try every unit separately to confirm this is the issue and not a problem with the Ac unit.

Any tip or clue here?
