@jseymour Sorry for the drop off. Been traveling.
Yes, just checked again and it’s still connected! Wow. Never have I been able to see the Rachio in the Home app for longer than 2-3 days. But it’s still showing with the correct status when it’s running/off and able to control my zones.
I created a 2.4Ghz-Only SSID across my “site” (home), which consists of 3 APs. Rachio has remained connected to the closest one. Wonder what would happen if I rebooted that AP and let it “fail over” to the other APs… maybe a test for later, but the 2.4Ghz-only SSID has been working really well for Rachio.
