"/usr/local/lib/python3.12/statistics.py" is throwing an error - eh?

Core: 2024.2.0
Supervisor: 2024.01.1
Host: 11.5

HW: RPI 3 - booted from SSD (I know, I know - try not to hate me)

All seems to be running OK OK, except after install of 2024.2.1 or 11.5 (I can’t tell which) Log Viewer is rendering (only) this error:

strong text****self._extra_state_attributes[“rssi”] = round(sts.mean(self.rssi_values))
** ^^^^^^^^^^^^^^^^^^^^^^^^^^**
File “/usr/local/lib/python3.12/statistics.py”, line 486, in mean
raise StatisticsError(‘mean requires at least one data point’)
statistics.StatisticsError: mean requires at least one data point

Any ideas?

Thanks,
Woody.
