Firmware v1.55 (Beta) | LZW31-SN | Dimmer - Red Series (Gen 2)

I’m starting to see some odd behaviour with dimmers that have been updated to v1.55(beta)

Initial testing all looks good. However, after running with it for about a week I’ve had a few occurrences where the on/off state reported by the dimmer does not match the actual state of the load.

In other words, it seems to work fine for several days and then at some point I notice the lights are off but the dimmer is still reporting to the hub that it is on. The LED status bar is also indicating ‘on’ status, but the load is off. Its also reporting a low wattage reading to the hub (probably the power of the dimmer internals and LED status bar). It seems like the load output circuit gets out of sync with what on/off state the MCU thinks its in. I can use either the physical button or zwave command to toggle off/on to get things back in sync again.

This has happened more than once, but I haven’t yet figured out what makes it happen or how to duplicate it reliably. It seems to just happen after several days of working normally. I’ll keep monitoring and paying closer attention to any pattern. I’m curious if anyone else running 1.55(beta) has seen something similar.
