BTHome (for Shelly BLU Button1) OK on HAOS, not on Core?

Third party integrations
1

I’m trying to integrate a Shelly BLU Button1 with an ESP32 (Wemos C3) configured like this:

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true

bluetooth_proxy:
  active: true

After days & hours of searching, reading, a lots of trial and error, as a test, I fired up a HAOS instance in which I got it working fine immediately.
I also got the ESP device in my main system (HA Core) but the remote is not discovered nor can I add the BTHome integration manually: it throws a ‘No devices found on the network’ message.

What am I missing?

Just now, ‘out of the “blu”’, first the iBeacon integration popped up and pressing the button also made the BTHome integration to appear! YAY :sparkler:

I don’t understand how this could happen but sometimes I don’t wanna know!

I don’t know for your button, but some BLE devices (if not all?) can connect to one instance at a time only.
Example: Xiaomi BLE thermo/hygro sensor: if i connect it to my test HA then it’s not visible in my main HA and vice versa.
Another example: LD2410 presence sensor: if you connect to it with phone app via BT it’s not visible in HA (if it’s connected to HA via BT connection). Thus said, you also can’t connect to it with app if it’s already connected to HA - you must reset the sensor for that to achieve.

So, in short: these devices can’t co-exist in multiple environments.

Hi Pavel, thanks for your info, I didn’t know that! :+1:

But, I did try at first with my Core setup so the button was new, never used here so it couldn’t be paired with something else.
After a lot of reading, trying, frustration I decided to use a HAOS setup which made me more familiar with BLE/BTHome (I wasn’t sure what I had to do to get my ESP device working as a BT receiver and what had to be done in HA) and the setup on HA, it seemed something related to my Core setup.

You know, somehow I’m still curious what was going on but like I already wrote: sometimes I don’t want to know why and my good feeling of having succeeded in something is much more bigger then my curiosity. :grinning:
