ZigBee Fan Switch not updating switch or speed parameters

Howdy!

I'm cross linking posts between here and the Inovelli forum where I initially asked the question, but basically I have several of the VZM35 fan switches in my home. All are using the latest driver from GitHub, all are running firmware version 1.07. I just replaced one of the switches yesterday due to a hardware issue, and the new one will not report its speed/switch state to Hubitat properly. Even if I do a refresh or initialize, the switch and speed properties are pretty much always wrong. This also translates, of course, to any outside control API like the Maker API or HomeKit, etc.

I’ve confirmed the switch has great connectivity, it receives and acts on all the commands I send it instantly, the RSSI is solid (-28%), etc. I’ve tried ZigBee network rebuilds, I tried shutting down and unplugging the Hubitat hub (C-8 Pro, version 2.4.3.133) for a while to clear the radio, I tried popping the switch’s air gap for a few minutes, nothing has helped.

It’s just this one switch. The others are all working fine.

Anyone seen this before?

For grins I excluded the device from the hub, did a factory reset on the switch, rebooted the hub and then re-included the switch. Same behavior: it doesn’t report status updates for switch or speed - all commands are executed (LED flashes, speed changes, power on/off, etc) but the device never updates those two parameters. Most recent command executed, internal temperature, RSSI/LQI etc all update correctly in the Hubitat dashboard. Something is weird here.
