Just the one here a 3b+ running octoprint. I did fiddle around with it a little and did quite like it. Some of the projects in here are really cool. I keep meaning to get one to play with but have little real world use for them aside from tinkering.
Ah I didn't realise they made one with a CT clamp, although that's quite expensive considering you could make something up for quarter of the price. Which is unusual as shelly devices were pretty well priced.
I now have 4 Raspberry Pi's. The 4th arrived today unexpectedly, a free Zero 2 W from Magpi Magazine.
Pi Number 1: 8Gb PI 4 which is used as a desktop computer/talking to headless Zero machine.
Pi Number 2: 2Gb Pi 4 running Apache and I am using it as a server to test my web programming on.
Pi Number 3: Pi Zero W which is running headless and used to photograph Hedgehogs in the feeding station.
Pi Number 4: Pi Zero 2 W, which is sitting in an antistatic bag waiting to be found a use for.....
All these Pi's and I do not even have a wispy beard or strong spectacles.
