@Qmit Unfortunately this Pre-Release firmware 1.7.0 is only for Deco M4 (V1) and (V2) not for (V3)

@David-TP Here u can see my Midea Lounge AC is at Ground Floor Lounge and also i select the AC to connect to only Ground Floor Lounge Deco Unit but when i reboot my whole Deco System and after that...

@JunkieXL411 I think your new ONU is faulty or your ONU firmware is faulty.

@Edmundas You can install the 1.7.0 Pre-Release Official Firmware then try again

@hrreddy Go back to older firmware and check

@Himanshu-yadav Maybe tomorrow Monday or next Monday
