Inovelli blue series loses communication with C-8

I recently received a new Inovelli Blue Series 2-1 switch, paired it with my C-8, and configured it as a dimmer. Immediately after pairing the switch responds to commands. Initially, the device worked fined and responded to commands foe several days. But after a few days, stopped responding.

I pulled the air gap switch, pushed it back in, and the device resumed working as expected. However, after a few minutes, it stopped responding. After having done the air gap procedure a few more times, the device has been responding for the past ~6 hours.

This is the light fixture being controlled:

Earlier, I noticed in the logs these errors associated with the device. However, I’ve noticed that they have since stopped being written:

I have verified that the device is not one of the earlier sets of bad devices. Zigbee ID: B43A31FFFE26E2CF

  • firmwareMT: 122F-0101-0102020F - appears to be v2.15?
  • manufacturer: Inovelli
  • model: VZM31-SN
  • softwareBuild: 0102020F

I’m also reviewing this thread for potential insight:

I am experiencing this same set of symptoms (reconnect switches but after a couple of days they are not controllable any more). HE c8, inovelli blue v2.15, not any of the two recalled versions. Did you find a solution?

No did not. I’m thinking about contacting support and perhaps shipping them back for review and perhaps repair. But I was just experimenting with the blues. So not a high priority for me right now.
