Daikin Madoka BRC1H bluetooth custom component

bibzou1 · December 21, 2025, 9:30pm

Bonjour,
j’utilise un PI4,avec Home Assistant OS 2025.12.4 ,et mon PC est sous Linux.

J’ai suivi les instructions de la page suivante :

Tout se passe bien jusqu a l’etape 9 ,le PI reconnait Madoka avec les commandes du github.
Dans la partie config du serveur ,j’ai crée:
[adresse du serveur]/config/custom_components/(images,translations,climate.py ,…etc)

Une fois la connection effectué entre BRC1H et PI4 ,l’integration “Daikin Madoka” n’est pas reconnu dans la page “Appareil et service” de home assistant.

Une idée?

Merci pour votre travail.

First, and most importantly, thank you to everyone who has helped make this component a success. I have been a long-time HA user, and my AC is one of my last significant steps in this journey.

I have worked on this on and off for the last year or so, and made progress every time. After several days of frustration and reading this thread a dozen times, I thought I would ask for help.

My AC has two Daikin BRC1H63W controllers. For testing, I have been testing on a single controller. It is located centimetres away from the ESP to ensure there are no range or interference issues. I can compile the ESPHome yaml file, connect to the unit, and the debug messages seem happy. In the Home Assistant, the dashboard always shows the unit as off. In the debug messages, it does not reflect changes in state from the controller and all readings from the unit are reported as NaN, such as below:

[14:24:10.647][D][climate:426]: ‘Bedrooms 2 and 3 Madoka Device’ - Sending state:
[14:24:10.649][D][climate:429]: Mode: OFF
[14:24:10.655][D][climate:449]: Current Temperature: nan°C
[14:24:10.662][D][climate:453]: Target Temperature: Low: nan°C High: nan°C

I am not sure where to go from here. I hope I am missing some nuance while reading the various posts in this thread.

I have attached photos from what I believe is a successful pairing, the corresponding logs, and my YAML file. I am apparently only allowed to attach one image to a post as a new user, so I can attach additional photos or screenshots as needed.

Thank you in advance for your help. I am grateful and humbled by this fantastic community.

Hi @Petapton and the community,

I’m using your component from github://Petapton/esphome@madoka and experiencing a permanent connection loss roughly 2-3 hours after a successful pairing. Once it drops, it never reconnects until a full reboot of both the

ESP32

and the Madoka unit.

Symptoms:

Initially works perfectly for ~2 hours.
Logs begin flooding with Connection failed, status=133 and reason 62.
The Madoka display sometimes shows a Bluetooth icon as if it’s still connected, but the

ESP32

is in a loop of failed handshakes.

Environment:

Framework: esp-idf (ESPHome 2025.6.1)
Hardware: ESP32-WROOM
Signal: -64 dB (stable)

Is there a specific scan_parameters or ble_client configuration recommended to prevent the

ESP32

from losing its session? Has anyone found arduino framework to be more stable for long-term Madoka connections?

Thanks!

Some logs:
