Zigbee device last activity vs last checkin

I have a couple of Aqara devices: a vibration sensor and a leak sensor. Initially, they did not work with the C-8 hub, but I was recently able to add them back to the system.

I am using the Xiaomi Aqara Mijia Sensors and Switches community driver for the vibration sensor and the Zigbee- Aqara Water Leak Sensor driver from Oh-La Labs for the leak sensor. The drivers are available through Hubitat Package Manager. You can see the release notes here:
