I use my rachis 2 gen. for a few days. It is working with my wifi (strong signal). Yesterday I saw that my Rachio is offline. Why? I use many items with my wifi, like netatmo weather station, netnetatmo thermostat and cameras - and these devices are still online. Yesterday I couldn’t connect my rachio again to my wifi. I reset my router, I disconnected from the power supply and connected again. Nothing, than suddenly, rachio connect to my wifi It worked until today 11.00 am. In the morning. At 5.00 am I used manual watering, rachio was online. Everything was ok. What could be the reason, that rachio is again offline?
