I have an MQTT server and Home Assistant server on the network. I want to get the CPU temperature sent to Home Assistant via any available method, easiest is best. I tried os-telegraf, but there appears to be no option for sending the CPU temperature.
Any help on the easiest, safest method to do this would be really appreciated.
I personally haven't tried it yet with my home assistant but this looks promising? It specifically mentions CPU sensors as stuff it pulls in.

I use that integration and it shows the temps:
