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?
