Subject: [weewx-user] Re: MQTTSubscribe service - not getting extraTemp1 or 2
The values come in as C and I wanted to convert to F. For some unknown reason
WeeWX seems to be trying to convert to %???
Interesting, I removed units = degree_C and it started to run without errors
but it shows on the skin (whatever the default is) RTD Temperature 20% and
TMP117 temperature 18% for temperatures of 20.46 and 18.09 respectively - I did
change the weewx.conf to show under labels generic
extraTemp1 = RTD Temperature
extraTemp2 = TMP117 Temperature
extraTemp3 = Temperature3

Well that change helped and shows MQTTSubscribe reading the values but now it
says can't convert degree_C to percent as per the following for rtd_temperature
(same for tmp117_temperature)
Also what should I do when copying sections of weewx.conf to make it easier to
read?

In that case should [[[topic/rtd_temperature]]] be just [[[rtd_temperature]]]
perhaps ???
It's a bit hard to decipher with such a cryptic description and unfortunately
google ate whatever formatting you entered on your cut+paste, so your original
post is very hard to read as a result.
Give it a try. It's already not working so you can't make anything worse.

without the xargs
rtd_temperature 20.70
tmp117_temperature 18.33

How about you just show the mosquitto_sub results without the xargs pipe
please...
