Question about EcoFlow Smart Plug CH

Yes, of course! That's what I've done. I've got my whole 'office' on this smartplug. That includes my PC, my speakers, my screen, etc.

An alternative smart plug solution is the one from Hombli, which can also measure the exact power consumption. A set of 3 costs only 52 francs.

Hombli Smart Swiss Socket 2+1

Of course you can!
