Rachio3 powered on and registered 4 weeks ago. No valves attached, just unit powered on for 4 weeks. Then received “offline” alert. App confirmed offline. Front of unit display full width blue bar. Powered off, waited 30 seconds, powered on – now totally dark front panel. No signs of boot. App still shows unit offline. Unit is very, very warm to touch on right side. Anyone see this phenomenon? Any fix other than replace unit?
