SONOFF mini trigger smartthings switch

I’m using a set of contacts on my lorex camera system (Alarm out) to trigger a SONOFF mini that I have connected to my outside lights. When cameras detect motion they can turn my outside lights on

I wanted to take this one step further and have the SONOFF mini trigger a smart switch in my bedroom that’s connected to smartthings or even alexa.

What would be best way to do this.

Within add automation in the Smartthings app, you can do:

Device status: [Sonoff mini] On

Control Devices: [Bedroom smart switch] On

If necessary, depending on your needs, you would do the same for off.

There will be a slight delay, maybe a second or two, but nothing drastic.
