Hi, welcome to the community.

It works. However, I'm not sure if it is what you want to achieve.

The powerline adapter TL-PA7017 would not join or become part of the Deco powerline Mesh.

General Questions about the Powerline or PLC Backhaul Feature of Deco

If you have a PA7017Kit, two adapters work like a long Ethernet cable to provide an Ethernet connection for a remote desktop.

if you have 7017 and another wireless powerline adapter, the wireless network from powerline adapter would be a separate wireless network for mobile devices.

Best regards.
