For the future, you could ask BG if they intend updating that model to have Matter support. Matter is a new industrywide standard specifically intended to make it easier to integrate devices from different platforms. Smartthings already supports it for one way in. So if BG does update the socket to support matter, you’d be all set. But while some companies are updating existing devices, others are just coming out with entirely new matter, compatible models, and some are taking a wait-and-see position. So it’s not here yet, but eventually, this whole issue should be much less of a pain.
FAQ: What do I need to add a Matter device to the SmartThings app? Do I need a bridge router device?
