You could also have a look at OpenHAB as a control platform. It could read in all the data from 100’s of sensors; graph them out, and provide cloud connectivity. You can run the server on a RaspberryPi.

on top of that, it offers a pretty robust and powerful rules engine. You could, say, turn on a light at each unit requiring water.

The Zwave stuff i’ve worked with only supported “mesh” / “repeater” modes if they were wall-powered. The battery devices didn’t have it. At least not on the few things I’ve used. Obviously acting as a repeater could use more power than just “wake up and report status” then going back to sleep.

Nice start.

Have you considered doing NDVI imagining to verify that your plant is under stress to help calibrate your stress analysis?

Nice start to your design challenge. Mesh networks offer a lot of advantages, when it comes to large and convoluted networks. But they can also present some interesting problems/issues. I worked on a Zigbee mesh solution to office/parking garage/warehouse lighting systems. The mesh was very good at finding good connectivity through some of the complex floor plans that we installed our systems in, but sometimes there could be throughput issues as message 'storms' could pop-up, were message throughput would suffer. Some of the solutions required 'throttling' message rates from individual devices such that they did not over stress the network. Hopefully with your smaller, less dense network, these will not be problems for you. It is nice that you have already begun to consider work arounds should the mesh not work for you.

Good luck on you project!
