I would be VERY interested in buying an accessory for my Iro for monitoring the actual water flowing to my irrigation system.
- Accurate Zone Water usage - It would allow us to know exactly how much water is getting to each zone, since the Iro can sync the flow with the schedule of which zone is being watered.
- Broken Sprinkler Detection - The Iro could learn what the normal flow rate if for an area, and it if seems unusually high it can notify the owner with an alert, and possibly even turn off the sprinklers as a precaution (if desired by owner)
Create WIFI enabled Water Gauge device
a. that the Iro can access via an IP address directly on the local lan
b. The device could send data to the Rachio cloud server, and the Iro can get the data from there.
Irrigation cabling - I have a few spare wires that go to the irrigation valves, that could be used to connect directly to the Iro, if that was an easier way to get the data to the Iro. Of course that would have to implemented on a Version 2 of the hardware. Example devices at: http://www.futurlec.com/Flow_Sensor.shtml
Z-wave Water gauge device - using home automation device which are becoming more popular, the data can be collected and sent to Rachio cloud server. SmartThings and VeraLite are very popular, and I’d bet most Iro owners have one of these.
