How to integrate these Humbli wifi switches in HA?

for testing purposes I ordered a Humbli smart socket.

it is connected over wifi to the Humbli cloud… and is visible in the Google Home app. Working fine, and showing all power readings I was looking for.

It is detected on the network aan an esp device, but, and here comes the quest: only as a device_tracker showing home/not_home.

Ids there a way to integrate devices like this into the Home Assistant entities as a switch with power sensors? Sync my devices only syncs HA devices to Google, and not the other way round.
It seems not to be Homekit compatible, but even when so, (like the Eve smart switch) that wouldn’t make it available in HA without support in the Homekit controller add-on.

so, anyone with a golden suggestion? Thanks!
