How to make Smartwatch vibrate

I a working on a kind of a alarm system. However I don’t 100% trust my implementations and I usually wear my Smartwatch during night to wake up silently without disturbing my wife and baby in the morning.

Now I would like to build some alarm rules to trigger when e.g. window sensors or motion sensors recognize activities during the night.

What I tried is e.g. using callmebot to perform a telegram call - unfortunately when the mobile phone is set to night mode. the smartwatch does not ring.

Does anybody have another idea to make the smartwatch vibrate? (It’s a samsung Galaxy Watch 3)

I just use the standard openHAB notifications and make sure that openHAB notifications are not suppressed during the DND period.
