Paring a used Elko Smartswitch 10A

How to get a used Elko Smartswitch 10A to connect to Homey Pro?

The userguide to Elko doesn’t solve the problem.

Reset: 3x press on button, 1x press within 10 sec?

The manual says three clicks shorter than 0,5s, then one long click more than 10s.

Thanks. Misunderstood the usermanual.
