@darkoperator The link is below. Keep in mind the device code alone isn’t perfect, it’s best to create virtual devices for each relay to have the best results with status and for use in other apps/hello home actions etc. But, it does work and it works well. I’d say buy one give it a try, message me with any questions. I’m more then happy to help, I got lucky getting it to work. Hopefully someday ST will properly support dual relays.
