Cannot turn on Delonghi Primadonna anymore

[mannipulator]

Hello, thanks for this great integration, I love it !

Since the last release my Primadonna stopped working, which means I cannot turn it on by Home Assistant any more.
The status, like descaling, is it running or not seems to work, these entities update if I turn the Primadonna on manually.

In the protocols I have after each try to turn it on 2 logs, a warning and and error:

this is the warning log:

I hope this helps ;)

What Bluetooth adapter are you using? How many other Bluetooth devices are you accessing in HA? Are you using Bluetooth Proxies? Is the coffee machine far away from your HA device?

I have the same issue as @mannipulator with the same machine (Delonghi Primadonna). This integration is the only one using bluetooth on my home assistant system. The machine is aprox. 6m away from my bluetooth adapter which worked fine with this integration for the last months. I am using a TP Link UB400 Nano bluetooth dongle.
The integration does recognize when my machine gets turned on.

EDIT: It seeems like the entity ID changed! Setting it to "button.kaffeemaschine_turn_on" (kaffeemaschine is the name of the device as I set it up in the integration) instead of the old "button.turn_on_ecam" brought everything back to work!

In my case, the problem has probably solved itself and everything is working as usual again. Nevertheless, here is some more information about my setup:

HassOS on RPi4
Home Assistant Version 23.11.2
Delonghi BLE v1.5.3
Devices connected with Bluetooth: 2

[mannipulator]

Ok it is back again
After each major update of HASS, the integration stops working.
I recognized that if I turn the Primadonna manually on, the Bluetooth symbol on the display appears around every 10 seconds for less then a second and then disappears. Maybe that’s a sign of a failing connection.

here is the log:

Is the app working for you? Not being able to find the MAC address at all suggests that the coffee machine itself is not broadcasting or not within range of your Bluetooth adapter.

[mannipulator]

No, it stopped to work now completely, I cannot get any connection to the device.
