Mount directly to wall if no box present. No need for anchors, use any small screw into drywall- will hold fine under wall plate. Pico weights practically nothing. That is one of the best features of the pico.
Yes, these are the exact circumstances that you need this wall plate. I have done it several times and it works very well.
Any lighting that works with the Caséta dimmer will work with a Pico switch. You must have a dimmer installed to use a Pico switch with it. A Pico switch does not work without being paired to a dimmer.
Any Decora style wall plate will work. I don't like the switch plate provided with the wired switch and prefer to buy a style that matches my decor.
I don’t remember what the cost was. It is the only way to mount the Pico controller using a wall plate.
It can be ordered online, which takes time to do.
