Hello guys, I have the same exact problem. I got an EASUN 3.2kv inverter and a WIFI plug pro 05 connected to it. All lights are on. Settings were done correctly and for 2 weeks worked without a problem. After that, it stopped and just showed an offline device. No more stats. I tried restarting the inverter, re-done the WIFI connection, removed from inverter for a couple of days then added it back. Removed and re-added to Smartess app with the same result. Has anyone else had/have this? Any ideas I can try to make this work again?
