A while ago there was an ad on Facebook for a 3 pack of water sensors with the hub for $39. Great deal so I bought it. In January, I was looking for an automatic wifi hose/faucet controller for an irrigation system I was planning and saw this. At the time, on Amazon, it didn’t specify that there were different generations of wifi hubs. It just said you needed a b-hyve wifi hub, which I had. I just found an open box controller on ebay for much less money than buying a gen 1 wifi hub, so I bought that instead. I wasn’t going to give Orbit any more of my money.
