Just to, maybe, save someone some time.
I was trying to import the temperature sensors of a remote machine to my HA through the Glances Integration.
Everything was going according to the documentation except of two things, the auto-start instructions didnt work and, after i figured that out, i could see all the data but no temperatures.
So, about auto-starting, the documentation refers you to this link, where for my case, i had to change
ExecStart=/usr/local/bin/glances -w to
ExecStart=/usr/bin/glances -w and that fixed it.
About the temperatures, turns out that glances start their webui / api service with the Sensors plug in disabled. I found here the solution to enable it:
/etc/glances/glances.conf to enable the plugin:
# This plugin is disable by default because on some system, the PsUtil
# consume a lot of CPU to grab the stats...
Now both the webUI and home assistant get information about the temperature sensors.
Hope this helps someone
