Clearly I have too much free time this morning (wife is sleeping in) and I'm playing around w/other button drivers I'm finding...tried the Konke driver that @arnb posted about above, and interestingly I can control button events from the device page (I set up an ABC automation to toggle a light).
However, pressing the button does not work to run the automation, but tapping the Push command does.
Thread:
Driver: hubitat/drivers/konke-zigbee-button.groovy at master · muxa/hubitat · GitHub
Logs - the button press events are from the Push commands on the Device page, the physical button presses aren't showing up in the logs and don't toggle the light.
So this driver may at least be close? Not getting "null" values as w/other drivers.
