Hi, Rello
I have the exact same problem. My Deye inverter and stick logger was working perfectly for 24 hours a day since August last year on Solarman Smart. However, on the 27th of March 2023, that all changed, and Solarman started showing portions data logged or none at all. Nothing changed on my side. On the Solarman app, my logger is online but my inverter offline.
Have you managed to get a fix?
Regards
E
