Hallo, do not change zero input of the smart micro solar. In my case with the firmware around 2 Month ago the smart micro solar shuts down fully the micro inverter.
To get rid of Zendure cloud behaviour, i would set the output to max micro inverter input. Make shure that the accu will not full depleded. Of course you need to feed the smart micro solar with power consumption information via shellys or other devices which can communicate with the smart micro solar.
