I'm quite new to network hardware/software configuration, but I'm willing to learn. I usually like to tinker a bit before asking, but for that project I'm a bit scared to jump in, so I'd appreciate some feedback on my ideas first.
I have in mind an experimental setup idea, for which I drew a sketch:
- I'm thinking of OpenWRT because I'd like to gather data from the access point, such as number of connections and their quality.
- I'm thinking of Raspberry PI mostly because I have a very tight space available (and I have a 3B+ on hand). I will need a wifi dongle to extend the number of device connection, as I've read it here.
- I'm thinking using Power over Ethernet to have a single cable between the technical box and the waterproof enclosure. For that I need some PoE modules and a power injector.
- Eventually, depending on some data thresholds defined on the RPI, I'd like to control actuators using an Arduino. For the RPI to communicate with the Arduino using a RJ45 cable, I assume I'll need a switch.
Am I correct on my hardware assumptions?
Any advice will be welcome!
