UcmPI not communicating with Comfort - Howser - 10-28-2025
I upgrade to Comfort 4.x a few days back, I had to restart the ucmPi tonight after updating my network gear. The ucm can no longer be polled, the pi seems to reboot as node-red seems to be running.

You mean Comfigurator v4.0.3?
Comfigurator cannot affect the UCM/Pi and cause it to rebooot. Can you try it with Comfigurator 3.14.14. Comfigurator 3 is noty uninstalled when you install comfigurator 4

I am not saying that is the cause, I am saying the only changes lately were the Comfigurator to v4.0.3 and the firmware updates, nothing else was done on the setup. Using Comfigurator v3.x does not make any difference.

The reply UBF2 means that the UCM/PI firmware has been corrupted somehow. You can try to use the UCM with firmware programming cable to ureprogram the firmware of the UCM/Pi

Thanks, I have never done that, can you walk me through the process or point me documentation that goes through the process?

The UCM/Pi software will automatically reboot if it does not see the Watchdog toggling the Output pin every few seconds. You can click on the pause button while you are debugging to prevent this:
