core Could not add HomeKit device Onvis CT3 Sensor

The problem

I have been using 6 Onvis CT3 sensors for a year now. In the past, I was able to add the devices to Home Assistant in the following way. First, I added the sensors to Apple Home via the Onvis app and checked for a firmware update. I then deleted the sensors from Apple Home and the devices were offered to me as new devices in the Home Assistant. The code was requested during configuration and the device was successfully assigned to a room. Since the Home Assistant update in September, the sensors were no longer accessible. I then deleted and reset the sensors. I then added them back in the Onvis app and updated the firmware again. Then deleted from Apple Home again. The sensor is then displayed again as an available device in the Home Assistant, then the device is configured and the code is entered. A message then appears stating that the device is already connected to another control unit. The rest of the sensor was also unsuccessful. What to do now?

2024.9.1

Additional information

First I connected the Sensor to HomeKit and the remove it. After this, HA found the Sensor, but after I have entered the paring Code the comes the message, the sensor is already connected to an other device.

I am facing the same issue after trying to reconnect an Eve Room device after recalibration. The very first time I connected this to HomeKit, then removed it from HomeKit and connected to Home Assistant as HomeKit device. Later, I reset the device to trigger recalibration and tried to redo the same steps. Connecting to HomeKit was not a problem, I then removed it from HomeKit. I then instantly get the option to connect as HomeKit device in Home Assistant and upon trying to pair it, I am running into the very same issue and receive the same error message.

I include the log as well as the last traceback seems to be missing from the above log:

Are there any new findings on this. I can't use my CT3 Sensors.
