Any updates?
I just looked at the install vid and saw that there are two holes on each end of the switch face, one for the screw to mount it to the box the other for snapping on the faceplate. And that hole isn’t threaded (or sized) to accept a cover screw. So the issue is, it may be compatible with decora style faceplates, but only the snap-on, no visible screws type. That is, you can’t use decora style screw on faceplates, only the snap on kind. And if memory serves, costs a fair bit more.
I really welcome the Wyze switch, really a good fit
I actually would like a 4 channel (button) like X10 Leviton 4x2 button HXCD4 controller to control my wyze devices.

The picture taken from the install video would infer that you can screw a standard switch plate to the switch.
And for the 3 and 4 gangers that might have switches in the middle where you don’t want to put a smart switch Eaton makes modular covers that let you build as needed. There may be some other manufactures that make something similar but I have used these and they work well.
R. Good, I disagree and that is the point of my previous post. There’s no hole to screw a standard plate too. The hole that would be used for that is the hole that accepts the snap on cover. As such, it is bigger and non-threaded.
I don’t follow you. The snap on faceplate does not require a screw hole. the two small holes at the center top of the switch seem to be in the correct position for the screw holes of a Decora faceplate. Remember that the Decora faceplate screw holes are not in the same location as a standard switch faceplate. The larger screw holes in the smart switch are to attach the switch to the switch box enclosure.
Another Edit… Not one to be found in 3 stores… Ah well.
EDIT: Trying to get one in hand… the 2 Home Depot stores near me seem to have an e-comm to actual inventory issue… which does not surprise me.
I will have a Wyze switch in hand shortly and will validate the Wyze setup. My local HD has some in stock no harm in the 14 bucks to get this solved, even with some on the way direct from Wyze
Everything below IS NOT WYZE
A different brand I have all through my home is similar and it comes with a snap on plate, but I have used standard/decora covers on this brand all over including ones similar to the OPs concern/question.
The holes on that brand are also not threaded but will take the standard plate and “self-thread”.
I’ll keep trying to get my hands on one ASAP, but I am optimistic that a standard Decora switch cover (rocker in this case) or any other variation as needed will fit on the Wyze switch. Similar to the smart switches I have used.
I would call it a “Decora” style switch plate instead of “standard switch cover” to avoid any confusion.
I’ve had experience with a few different brands of smart switches that come with snap on covers, and all have been set up to accept a standard Decora plate.
As for the holes not being threaded, keep in mind the screw is going into relatively soft plastic, not metal as with most standard Decora switches.
Here you are team.
1 Wyze Single Pole Smart switch
1 Decora Switch Cover
Fit right up
The left is a Wyze switch that has not received a cover. The right is the Wyze switch that I tested on. The cover screw threaded the hole.
Let us also take a moment to recognize that the box mounting hole looks an awful lot like the Batman symbol…
And it’s on a light switch 
Thanks for posting!!! The only question I have looking at the plate mounted on the switch is, have you tried to mount it yet? It looks like the plate will be sitting out about 1/8th of an inch from the wall because the Wyze switch mounting plate is so thick hence the thick snap on plate. Thanks!
This is exactly my result with adding the wyze switch to a standard dual gang box with cover. (not decora). I came here looking for a solution! Switch mounted to the wall, then cover plate screwed to the switch…
So is there an actual solution for this? As @halloweenman 's pic shows, the Wyze Switch is too thick for a standard “screw on” wall plate. As in the OP’s pic, I have a dual switch with the standard screw-on plate. Would like to replace one of the switches with a Wyze Switch but don’t want the “crooked” wall plate result with one side sticking out away from the wall. And I’m guessing that even if I found a “Decora” snap on plate, that while it might work on the side where I would install the Wyze Switch, it wouldn’t work with the existing standard flip-switch? I’ve been holding off on buying the Wyze switch until I know that there is a cosmetically acceptable solution to this problem, so I don’t have one on hand to experiment with. Hoping that someone else has already solved this problem.
Nice one! I won’t to go to far Off topic but must share cause of your pic as I was just here. I was totally 
ing out.
I have yet to have an opportunity to install, but will soon. I have a 3 gang single pole group and will try with the non-decora plate soon and report back.
Alright team, so the 3 gang I wanted to replace today gave me some challenges due to how that area was originally wired (3 single pole switches that someone got fancy with), so I will have to come back to that at a later time and I went to something that was a little more “standard”.
While not exactly what the OP was asking I wanted to share my results with the non-snap on plate with the Wyze switch.
As you can see there is a bit of a gap, but this is not different that the other covers in my home (see below). Could be a situation of textured walls (which I am not a fan of) but not unacceptable to me by any means.
For those getting gaps I would say make sure the drywall around your box is as clean as possible and that you try to get the wires into the back of the box as clean (don’t just shove them in pressuring the switch to push them back) as possible. so you can get a tight fit with the switch to the box without stressing one side over the other, these seem to be able to flex a little.
