I've been looking for some kind of raspberry pi management portal for about 2 full days now, but I never really get what I need.
We're currently working on some fun gadgets for our presentation room at our office and we're looking at expanding in the future. At the moment we have 3 raspberries (1 RBP zero and 2 RBP 3B+). They are all on the same network and their IP addresses should be static.
At least 2 are running on a their own 4000mah powerbank, but the third one should also use one in the future. I hope to replace them with better/smaller ones that last longer or 3d print a charging station.
I was thinking about adding a cronjob to automatically shutdown the pi's at 5 PM, but the batteries probably won't even last that long.
Like I said, I tried a few iot management portals, but they all seem to be geared more towards data collection. All I need is a simple application that allows adding new devices (fill in IP and ssh password), ping them to see if they're reachable, a reboot and a shutdown function. The "sleep mode" after shutdown is fine for now I think. I read that the pi typically uses 20-30 mA.
