Hi.
I should sudgest to investigate a brand from Sweden named Plejd.
It’s easy to install in old or new system.
It is based on Bluetooth and are use in small to large installations on power sockets and lamps plus switches.
You do not need any hub
Easy to install in Homey also.
I have it installed in two houses and been running on both Home Pro (Early 2019) and ( Early 2023)
Regards
Mats
