Cannot access the Hardware Clock via any known method #7

Seeing this error on my Raspberry Pi 3 running HomeBridge OS. Output of hwclock —verbose:

Hwclock from until-linux 2.33.1 System Time: 1603204740.843831 Trying to open: /dev/rtc0 Trying to open: /dev/rtc Trying to open: /dev/misc/rtc No usable clock interface found. hwclock: Cannot access the Hardware Clock cia any known method.

Would appreciate any help. Followed the install instructions. My Raspbee II is brand new and I can’t use it.

Solved my one problem with one of the following:

1.) Fixed a non-blocking “low voltage” error by connecting to a stronger power source.

2.) Reconnected the Raspbee and made sure it was on the proper PINs.
