Had a handful of Iris V1 Contact sensors that stopped communicating. When resetting and re-discovering, the devices are found, but are just as non-operational as they were when they stopped communicating. Deleting the original device and discovering gets the units communicating again.
From looking at the logs, the failed re-connections appears as so:
[sys:1] 2020-02-06 08:38:59.025 pm Iris Discovery Stopped
[sys:1] 2020-02-06 08:38:58.876 pm Found Previously Joined Zigbee Device IrisV1Contact
[sys:1] 2020-02-06 08:38:22.813 pm Created Zigbee Device Iris V1 Contact Sensor
[sys:1] 2020-02-06 08:38:13.338 pm Initializing Zigbee Device 000D6F0003B29F2D, 33CC
[sys:1] 2020-02-06 08:37:59.019 pm Iris Discovery Running
With the successful pairing appearing as so:
[sys:1] 2020-02-06 09:01:27.232 pm Iris Discovery Stopped
[sys:1] 2020-02-06 09:00:49.021 pm Created Zigbee Device Iris V1 Contact Sensor

Is there a difference in device initialization/configuration when first connecting a V1 contact sensor versus when a previously joined device is discovered? Really more of a curiosity than anything else.
