Shelly Wave Shutter O1 O2 Output

I have a Shelly Wave Shutter and I’m looking to control Somfy Glydea60 curtain motors, which currently operate via RJ12 connection.

My main question is:

  • Is it possible to configure the O1 and O2 outputs of the Wave Shutter to work as dry contacts only (no voltage output)?

The idea is to connect the RJ12 from the Glydea directly to the Wave Shutter, but before doing so I want to make sure that O1 and O2 can operate safely without sending any voltage to the motor, only acting as relay contacts.

Has anyone tried this setup, or can confirm whether O1/O2 can be used as pure dry contacts?

Thanks in advance for your help!
