My 2 Mitsubishi rw35’s both blink when they cannot get IP address. Blinking stops when connected to home router. I today de-registered one of them, thinking the issue is with my home network. Blinking stopped when I connected my unregistered (i.e., not in MelCloud) unit to WIFI. Hence I don’t think it needs connection to MelCloud servers. I could be wrong, if so, someone please correct me. Thanks.
