This morning the app both on my android phone and iPad is saying the system is offline. Both my inverter and gateway are connected by Ethernet and I have confirmed that they are connected to the home network. The portal also appears to working and there are no fault indications with the gateway or battery. I have unstalled the app and reinstalled and logged out and back in again. Is there anything else I can try?
power everything off (pv strings, battery, inverter), wait 30 seconds and turn back on.
grenham12 you can connect to the http interface on the dongle and restart just the Comms - that might get you back online. (Works for WiFi - don't know about ethernet.)
Or I have seen a suggestion of restarting your router.
I had this same issue, app been showing system offline since about 3 hours. Power was on to AC3 inverter and 2 9.5kW batteries.
Turned off the router and the wifi boosters, left it for a few mins and turned back on. The dongle must have reconnected to the wifi as I can now see readings in the app, including "home".
I have A LOT of things connected to my wifi network - anyone know what the dongle shows up as on my list of connected devices in case this happens again?
