A Pi is obviously overkill, even a Pi Z w which we ended up using, but they are efficient enough for us, and more importantly, I know the system, and I could relatively quickly get it working using just bash on the Pi.
I was not really interested in learning how to program on a different system just for this.
We did some power analytics on the Pi and disabled a few things, sorry I don’t remember it right now.
The unit is placed in a semi public place where teenagers sometimes congregate and we don’t want to draw any attention to the device, so solar power is out.
A LoRa unit though could be interesting to implement, sadly my parents house is up a steap hill and there is no line of sight.
I have been thinking of experimenting with Meshtastic and LoRa for off grid coms due to the geopolitical situation here in Europe, might be worth it getting a few units to test out.
