Dome siren unable to connect to v2 smartthings hub

Hi jkp.

I have obtained the access code from smartthings support, but i also purchased a v3 Aeotec hub, which is also not connecting to either of the 3 Dome sirens.

I suspect i have dome something wrongs, im just not quiet sure what.

To begin with, i added Domes Edge driver following the link provided in this page - [ST EDGE] [RELEASE] Dome Siren (Official 2.0)

Verified the driver was added
Hub → three dots → driver → Dome siren ( And channel hub is registered with is Dome drivers ).

To add the device, as you stated above:
( Siren ) press button 3 times rapidly
( Smartthings app ) Add device → scan for nearby devices

After some time, the process times out, and no devices are found.

I have also tried to exclude them ( No devices are available )

I have reset the siren ( Multiple times ) by holding button for 10 seconds.
Confirmed batteries are 100% ( put them into my motion sensor )

I have 3 of these devices ( sirens ), none of which are visible to my hub.

i have also created a support ticket with Dome for further assistance.

Really appreciate you suggestions, im just not sure what is wrong.
