Yale Assure SL with IM1 and bluetooth proxy

[Yodel6683 (Ryan E)]

I am trying to set up a Yale Assure SL(with the IM1 module) as a HomeKit device with a bluetooth proxy.

It shows up in HA as a discovered device:

But when i hit configure, it eventually times out with:

The debug logs for bleak in HA are:

I have removed the lock from my Apple Home and the Yale app. I have also tried factory resetting it and setting it up from scratch.

No firmware updates are available for the lock in the Yale app.

Just to rule out a firmware/homekit issue, I have successfully added the device to my Apple Home directly and it works flawlessly.

Homeassistant is 2024.9.0 (supevisor mode)
ESPHome is 2024.8.3

Any ideas?

My bluetooth proxy config is pretty plain:

esp32_ble_tracker:
  scan_parameters:
    interval: 320ms
    window: 30ms
    active: false
    
bluetooth_proxy:
  active: true

I have tried with both active and passive scanning, and bumping up the scan parameters to 1100ms

I noticed that the last rssi in the bleak logs is None, which I’m not sure about. The bluetooth proxy is about 2m away from the lock with clear LoS so I don’t think it’s a connectivity issue

Hi! Were you able to find a solution to this?

[Yodel6683 (Ryan E)]

Unfortunately not.
I ran out of ideas after this post and haven’t come back to it since, but would love to figure it out.
