Randy, another option is to try the Community Driver that was linked earlier in this thread:
Linptech/Moes 24Ghz Presence Sensor ES1 Community Driver
Debugging a built-in Hubitat system driver can be difficult because its code is maintained and changed only by Hubitat. We cannot inspect or modify that code ourselves.
The Community Driver is open source and provides more device information and more detailed debug logging, which may make this problem easier to understand.
Have you ever used a custom or community driver before? If not, would you be willing to try this one on the Master Bath sensor? We can do it one step at a time, and I will help you through the process. Please do not change anything yet - just let me know if you would like to try it.
