Thanks for the help, vince. I guess you mean mosquitto_sub because I
couldn't get *mqtt_subscribe to work.*
*```*
n4mrv:~$ sudo mosquitto_sub -t application/7/device/a84041c14184b062/rx -h
192.168.1.10:

Lets see a "*mqtt_subscribe -t yourtopicname -h yourhostname*" command and
resulting output please, but the temperatures and humidity in your .txt
file at the top sure looks like strings to me. The syslog messages saying
'could not convert string to float' seem to agree.

Hello,
I have a Dragino LHT65 temp/hum sensor sending MQTT data from a RAK7244
LoRa gateway. Presently I also have a Seeed CO2 sensor sending data
correctly to weewx (Standard skin) via MQTT--this is working via Node-Red
on the weewx server (many thanks to vince and storm for the help setting
this up).
Not being a programmer, I thought it would be simple to copy the CO2 flow,
with certain modifications, and get the LHT65 running. Not so...
I have a connection at both ends of the NR flow but there seems to be a
problem with the format of the data being parsed and exchanged. I would
like to store the data as extraTemp3 in the db.[image: LHT65flow.png]
I am attaching a file of areas that might explain what the problem might
be; however, I can send any additional information that might be needed.
My setup is weewx 4.10.1 (setup.py) running on ubuntu 22.04.1.
Thanks in advance for any help for this.
Cheers,
Bob [grattans.org/wx]
