Everspring HAN01 doesn't work properly

I try to use an Eminent (e-Domotica) EM6556 on/off switch module, it looks very similar to an Everspring HAN01.
With the Everspring-app it’s added as a “simple z-wave device”. The device works, but doesn’t reply it is switched on (or off) to the Homey. Is it possible to add this device working properly?
