As a test I replaced service ComputerMonitor with service alarm (copied
from examples/alarm.py) and got a similar exception.

I wonder if line 1624 in units.py has something to do with the error
(arbitrarily, pick the US unit system:)
# Is the record None?
if record_dict is None:
# Yes. Signal a value of None and, arbitrarily, pick the US unit
system:
val = None
std_unit_system = weewx.US
else:
# There is a record. Get the value, and the unit system.
val = record_dict[obs_type]
std_unit_system = record_dict['usUnits']
