Problem: During initial setup, Rachio 3 connects to WiFi network (solid light 2) but fails to contact Rachio cloud (white blinking light 3 with occasional red blink). My router shows no Rachio device is connected (this contradicts solid light 2).
After many reboots, about 6 hours of self-debugging and 4 fruitless calls to tech support, I finally got it to work.
Solution: I changed my router authentication setting from WEP to WPA. This required me to add all my devices back to my network. When I tried the Rachio again it connected just fine. Not sure what was causing the issue, but it seems like changing from WEP to WPA fixed it for me.
@LeeC - that is a GOOD thing as WEP is swiss cheese for security. Yes, a PITA to re-add all your devices but better off. I think I’ve see this mentioned once before, along with not connecting to a network with no security.
A best practice would be to put as many of one’s IoT devices on a guest network, if the installed WiFi router supports it, instead of on the network with home computers with personal/private data.
