Leak Sensor Notifications Stopped Working

[cm76corbett]

I noticed yesterday that some notifications configured using the "Notifications" app are no longer working. I'm using the LeakSmart Zigbee leak sensors and I have them set to notify me via push notification if they detect water. It's been working fine for months.

I've verified the devices themselves still can issue an audible alert.

When I check "Zigbee Logs" under the "Zigbee Details" section in "Settings", it looks like there's communication between the sensors and the Hubitat. Here's an example:

Kitchen Sink Leak Sensor2021-09-09 11:32:15.079 profileId:0x104, clusterId:0x402, sourceEndpoint:1, destinationEndpoint:1 , groupId:0, lastHopLqi:255, lastHopRssi:-83

When I checked the "Logs" section off the main Hubitat menu, it seems nothing is getting logged there when there's a leak alert in addition to getting no alert on any of the mobile devices set to be alerted.

What's interesting is that I am getting push notifications from these devices for battery level and temperature, which are also configured using the "Notifications" app. It's just the leak notifications that are not getting through for some reason.

I look forward to any advice!

Update to the latest.

I sort of brute force fixed the issue by removing these Leaksmart devices from Hubitat and re-adding them. All worked after that.

My best guess is that a HE firmware update broke the relationship between HE and the Leaksmart devices at some point, and did so in way that made it impossible to detect without either testing devices regularly, or finding out after an actual leak.

The lesson I take a way from this is to proactively test my leak sensors at least once a month and especially after any HE firmware updates.
