tl;dr is that with this python script and one of the arduino sketches you can get an out-of-the-box remote sensing network with sqlite storage that is very easy to extend and hack on and has proven stable for over a year now.
The background:
I live in the countryside and wanted to find some ways to help out our neighbouring farmers with my trade. One of the things you see a lot of is remote things failing and going unnoticed -- unclosed barriers, electrified enclosures not strong enough, escaped animals, etc. In addition to this, there are some regular maintenance tasks -- opening/closing the chicken coop door, irrigation, opening/closing a greenhouse -- that are trivial to define programatically and can save a lot of time and trouble if automated.
This is the backbone to a set of other projects currently in the pipeline, but it also includes chicken coop door opener in one of the example nodes. I have some neighbours working on remote sensing for their solar-powered electric fence generator using LoRa. Overall this technology's mix of low-power and long-range transmission makes it an awesome tool for cheap, 'low'-tech countryside hacks.
