I’m not implying that I or anyone could simply solder those parts and make this work like a 16-zone controller though. The surface mount pads for those omitted parts are even tinned with flux on them. The Extra Space red: mosfets, yellow: capacitors, purple: resistors, blue: IC, orange: zone wire blockĮven though this is the board for the Rachio 2 8-zone controller, it appears to be the same board that would be used for the 16-zone controller minus a few parts. Once I got the controller apart, I found some interesting things. “Maybe I can rig a better heatsink inside,” I thought. Since I’m a tinkerer though, I decided to take the controller off the wall and have a look on the inside. It’s also probable that the controller itself is just getting old and needing to be replaced. I’ve also not made any recent changes to the network’s hardware, firmware, or settings. The controller itself is about 3 years old and during those years, I’ve never had any issue with it staying connected to my network. I tried contacting Rachio support about this but they insisted it’s my Wi-Fi network that’s the issue. Even though there is an eero Wi-Fi access point only 30 feet away, the added heat is knocking the Rachio 2 off my Wi-Fi around 5pm and it will only re-join around 2am when the temperature goes down. However, the recent heat wave has been raising the temperature in my garage where the Rachio 2 is mounted on the wall. It’s been a great timer for both the mobile app to configure the controller anywhere and has water-saving features like seasonal shift and individual zone programming. I do keep tall fescue grass and mini clover in both my front and back yards and have a Rachio 2 8-zone sprinkler timer. Instead, Salt Lake City saw a record tying 107☏ this past week. Normally, September brings temperatures in the 75☏-85☏ range. Utah, like most of the western U.S., is experiencing a heat wave. TL DR Rachio should have included an extra antenna in their v2 sprinkler controller.
