Issue with Z-Wave Shutter

Hello everyone,

I built a house this year and my project is to work as smartly as possible with the help of Home Assistant. To do this, I bought switches from the company Technisat (https://www.technisat.com/en_XX/Roller-shutter-flush-mount-M/352-22704-23058/?article=0200/9496). I am basically satisfied with the switches, but I have one problem: I have connected more than one roller shutter to the switch in some places. As soon as I press the switch, the shutters move for a second.

However, I have not seen anywhere that the switch is really only suitable for one roller shutter. What have I overlooked?

Do you have any ideas how I can solve the problem? I don’t want to tear the switches out of the wall again.

Thanks

K.

I’d call the company. I don’t see an example in their manual of wiring two motors to one switch.
