Hi László,
Thanks for your reply.
I asked if it was the RaspPi because it’s been out of stock, but you mentioned the Odroid HC4, which I didn’t know about.
Thanks for the explanation and the formula to calculate the yearly cost (approximately) to have the server connected 24/7.
I’ll look into Odroid and I’ll also check the consumption of my old PC.
I’ve been running tests with docker on that old PC and I turn it off when I’m done testing, but as soon as I have more time, I want to get it working, or an ARM 24/7.
Thanks for your help
Jorge
