Not sure if you are still looking for solutions, but I liked you idea so
had a look at implementing it in Python.
Turns out it was easier than I thought.
1) create a python file and put it into the bin/user directory, this file
gets the CPU temperature, coverts it to Fahrenheit and puts it into the
extraTemp1 column in the database
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
2) modify weewx.conf to call the new file
[Engine]
[[Services]]
# This section specifies the services that should be run. They are
# grouped by type, and the order of services within each group
# determines the order in which the services will be run.
prep_services = weewx.engine.StdTimeSynch
data_services = user.cputemp.AddCpuTemp
Now the value can be obtained anywhere you want by
referencing $current.extraTemp1
I modified about.inc in the seasons skin with the following
<tr>
<td class="label">Server uptime</td>
<td class="data">$station.os_uptime</td>
</tr>
<tr>
<td class="label">Server CPU Temp</td>
<td class="data">$current.extraTemp1</td>
</tr>
<tr>
<td class="label">WeeWX uptime</td>
<td class="data">$station.uptime</td>
</tr>
Also you can now access the dayTemp graph to see the plots over time
