Hello.
Since this is very interesting, I tried it right away. I created a python file
called cputemp.AddCpuTemp.py with the content:
import weewx
from weewx.engine import StdService
from gpiozero import CPUTemperature
class AddCpuTemp(StdService):
def __init__(self, engine, config_dict):
# Initialize my superclass first:
super(AddCpuTemp, self).__init__(engine, config_dict)
# Bind to any new archive record events:
self.bind(weewx.NEW_ARCHIVE_RECORD, self.new_archive_record)
def new_archive_record(self, event):
cpu = CPUTemperature()
event.record['extraTemp1'] = ( cpu.temperature * 1.8 ) + 32
and save this under /usr/share/weewx/user/
In the weewx.conf have it the Service: data_services = user.cputemp.AddCpuTemp
Now this error message appears to me:
Mar 26 09:34:29 raspberrypi weewx[1412]: engine: Loading service
weewx.engine.StdTimeSynch

Did I forget something there?
Thanks for Help
