Hallo.
Many users report that their systems are feeding in uncontrollably.
I've just got it myself with my SF800 PRO. When I go to Smart Control, the SF800 PRO controls higher and higher. The values no longer match the real values. It doesn't matter if I'm in automatic mode, Zenki or self-consumption mode. The SF800 PRO goes up to a maximum of 800 watts.
If I set my own value, the values of the Shelly 3em are also true again in the Zendure app.
Removing and re-adding the Shelly 3em, including removing the Shelly shortcut in the Zendure app, did not change it.
My SF2400 PRO shows no problems, whether with Shelly, Ecotracker or Zendure D0.
I always try to recreate your mentioned mistakes and then report them to Zendure.
I'll get back to you as soon as I get an answer from Zendure and hopefully a solution to the problem.
Greetings, Tim.
