I have a 1800 square foot home with 2 levels raised ranch style. I have 3 M4's and 3 M5's. I have been going on with out a hitch for years maybe had this happen one other time but it was an easy fix. I have a complete smart home with between 40-50 devices, including appliances and security. My entire deco network has completely disappeared. I have done all of the trouble shooting muktiple times with zero success. I tried re-addung the main deco in hopes that I would be able to update and refresh memory. I tried with multiple decos. I am a single mom with two small children and a full time job and I dont have time for this kind of thing. Not to mention the stress it causes because when things like my locks fail to work it quickly becomes a living nightmare. Please tell me there is a way to fix this or that my entire system is backed up on the cloud and i can somehow access through there. I visited other threads where the same thing happend and there were no answers on some of them and nothing helpful in others. I need help badly. This issue and how its resolv3d will seriously shape my future with TP-Link and like i said until now no real ussues of convern. Please help.
