I have Nous A1T with Tasmota firmware (they are available pre-flashed) for the normal power sockets and Shelly 1PM for in-wall Installation. Both work with home assistant flawlessly.
Edit: Shelly tries to communicate with outside servers (cant remember exactly which one, might only be time server and update server, but unsure) so they are in a VLAN without Internet connection)
