Got the hub, 2 TDR soil sensors, the environmental sensor, and pH/EC sensors for the reservoir. Also the OpenSprinkler (havent had a chance to play with this yet). Everything has been flawless so far, sensors hold calibration, the app has a good UI and has not crashed once or had errors. Setup was a breeze and at 1/3-1/2 the cost of some other systems, (with significantly less wires as well!) the value is great. I am using it for one zone atm but hope to expand and hope to see additional functions built in like light controls!
