I have not noticed this before but it seems Lowe’s sells the new SmartThings branded plugin modules. They are not on sale at the moment but this may be something to look at with coupon codes.
I saw That also at my Lowes. I hope they keep selling the better and cheaper Iris devices.
I like the Iris plugin modules as well. You just can’t beat the Z-Wave repeater. Only thing to note is that these are rated for 15A versus 12A for the Iris ones.
