Custom component (omnik-inverter) can not be found as integration component

I’ve downloaded a custom component from GitHub and put the files in /custom_components/omnik_inverter/ as statet in the description.
After restarting HAS i can see the following warning in the log:

WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration omnik_inverter which has not been tested by Home Assistant. This component might cause stability problems, be sure to disablestrong text it if you experience issues with Home Assistant

The componets seems to be loaded by HAS, but I cannot add and configure it as a integration?

Could someone help me on this?

Cheers, Erwin

The configuration doesn’t work? Or it can not be found?

It cannot be found

According to the warning it should be loaded. Are you looking in the right place?
Settings>Devices & Services and then the button “Add integration”

I’m at the right place and it looks all the same as in the description on Github, but the component is not there

And there are no other errors in your log?

a couple ot these:
2022-05-25 16:19:23 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [140397847642016] Received invalid command: energy/info

Error seems not to be realated to the omnik_inverter component, the error is still in the log after removing the component.

Found the problem, I had to enable ‘advanced mode’ under my profile.
