TP-Link Smart Home finds no devices

Hi, total newbie I’m afraid. Have got HA on Synology through container manager and while it fired up and found many devices, including Hisense TV and Sonos speakers it can’t find the 4 TP Tapo P110 I have.
I’ve researched for a few hours and many say the new firmware from TP blocked all local access but others say that have Tapo up and running on HA. All help appreciated.
