Shelly 2.5 controlling motors with reverse polarity

frankyglobal

Hi everybody.

Have to control a Somfy 24vdc motor that works reversing polarity for closing or open. I mean... if connect +24v to A motor wire and -24v to B motor wire the motor opens but if connect +24v to B and -24V to A the motor closes.

Solved it with 2x24v relays but would like avoid external relays and just using Shelly 2.5

Does anyone knows if Shelly can be configured for switching polarity between 01 and 02 sockets ??

Thanks ind advance

No.

You need the external relays.

Welcome to the forum.

Any chance to get a wiring diagram for this?

Also, can these relays be controlled by the Shelly 1 or we need the 2.5?

Thank you!

Only shelly 2.5 has a shutter-mode to make sure, the roller don't have signal up and down at same time.

okay, so can I use a shelly 2.5 with a 12V actuator by using a 24V to 12v adapter?

thanks
