@Vshra Nevermind, I've just seen this thread: https://community.tp-link.com/en/home/forum/topic/174132 That answers my question.

@Vshra Or just to update the request, would they be compatible with the AV1300 homeplug: https://www.tp-link.com/uk/home-networking/powerline/tl-wpa8630p/

Hi everyone. Are the new Deco Powerline Mesh Wifi kits compatible with the older AV200 and AV600 powerlines, and if so, will the older AV units place any kind of limit on the speed of the Deco system...
