[feature request] Show SoC temperature when not connected to printer

[rafalmag]

Would it be possible to show the SoC temperature when the printer is not connected?
Current workaround for me is to use Opitemp Plugin, but as your plugin supports various boards (including Raspberry Pi) I believe it could be useful for wider audience.
Motivation for this usecase:
I keep OrangePi in the same enclosure as the printer board, however I switch on/off printer mainboard (and thus its fan) separately. When the fan is on (printer baord is powered) the SoC is around 25-30C (even during printing!), but when it is off - the SoC goes up to 40-60C.
I would like to be more aware of this.

+1 for this, I have a system which turns on the Raspberry Pi fans only when the whole printer is on, and I would like to live compare the temperatures even when the printer is off.

@rafalmag and @Thorinair do you know how to do it? I was diging in plugin but I was not able to change it.

@rafalmag I found how to do it, but all temp on the same time or nothing
