I did some more troubleshooting this morning. I looked at the weewx-mqtt
code and saw if debug = 2, it would log the messages to the broker queue.
What I see are only F values being sent to the MQTT broker such as:
Jan 2 17:30:36 raspberrypi weewx[14221] DEBUG user.mqtt: data:
{'dateTime': '1609608633.0', 'usUnits': '1.0', 'rainRate_inch_per_hour':
'0.0041459842519685035', 'hourRain_in': '0.0010364960629921259',
'rain24_in': '0.7630002755905513', 'dayRain_in': '0.015043897637795279',

'0.0', 'windBatteryStatus': '2.58', 'radiation_Wpm2': '195.0',
'altimeter_inHg': '29.8730484820492', 'barometer_inHg':
'29.87618364623033', 'cloudbase_foot': '2760.0530237211146', 'dewpoint_F':
'37.791766695627096', 'heatindex_F': '46.367940000000004', 'humidex_F':
'48.70400000000001'}
I am still seeing C units coming back while debugging the dev tools console
when the Belchertown skin is receiving/logging the message like in my
original post. Scanning the belcherown.js, with debug it is logging the
incoming message so it is a head scratcher to me how one component is
logging the outgoing message in F (US) while a different component is
logging the incoming message in C (Metric)
