Eve Sensor not working with Homekit and Gateway 0.8

Hi - I am trying out Gateway 0.8 and have one Eve Door Sensor attached. For a short while the gateway registers the opening and closing of the device then I get the following errors:
2019-04-26 11:41:40.886 INFO : homekit: Update triggered for: 41:3f:52:ff:8e:32
2019-04-26 11:41:41.025 INFO : homekit: Error reading characteristics for device 41:3f:52:ff:8e:32: Disconnected

2019-04-26 11:41:48.804 INFO : homekit: Error reading characteristics for device 41:3f:52:ff:8e:32: Disconnected

The device is an 20EAL9901 which I believe is supported.

The gateway appears to be getting the trigger but then something else fails - any ideas please??

Thanks
Simon

Unfortunately, there seem to be Bluetooth issues either on the Raspberry Pi or in the noble library. At some point, the Bluetooth stack on the Pi just starts timing out on every call. The only way to recover is to restart the bluetooth service or to reboot the Pi.

Thank-you - I’ll work out when the error occurs and restart the service

I have written some code to check for the error . Restarting the gateway stops it - I had no need to restart the bluetooth service… it was about 2 hours after I had previously restarted the rpi.

I’m glad that works for you.

I’ve tried and tried to fix this issue, but cannot seem to track down the root cause.
