Have attempted to look at a lot of stuff but all revolve around their servers having to approve anything. I remember a power strip that refused to work wothout internet because it could not communicate with server for auth and actions. I have decided to go full diy and use relays and esp32 to power on devices and such. Use raspberry pis with home assistant to do the work.
