I see the waooz-1 which goes on top of a standard light switch, but does anything exist that goes in the wall and can do the same thing? I’m thinking of a switch that has a manual disconnect switch (like a standard dumb switch) and smart buttons.
Does anything exist like that which works with smartthings?
Thank you
Sure, There are now several of these. What country are you in? The device selection does vary.
If you happen to be in the US, both Zooz and Inovelli make switches that have a parameter that can be set so they can be used in this way.
Zooz is the house brand for the smartest house.

No more tape or sticky notes covering your light switches. Gain full control over your smart bulbs. By disabling the internal relay of the Red Series Fan + Light Switch, your lights will maintain their routines. Yeah, it does that too.
Both are popular in the community. Inovelli is a very small company which occasionally has supply chain hiccups, as right now, where they are out of stock of a popular item for a few weeks or even a couple of months. But nice features, excellent prices, a lot of people are willing to wait.
There are some other options as well, and again, some for other countries. But you definitely have more choices these days. 
By the way, there is an existing community FAQ on this topic if you haven’t had a chance to read it yet. 
Thank you for the responses. I did go through the whole FAQ which I’m not sure is fully up to date. The Lightify cover switch is discontinued.
I’ll look into the Zooz and see if that does what I’m hoping.
So it looks like I would need a Zen26 without a dimmer you don’t normally hook smart bulbs up to a dimmer.
Now the confusing part is that I don’t think the Zen26 has the ability to tell a smart bulb to dim via Zwave.
You don’t hook up smart bulbs to dimmer switches which control the current to the bulb.
It’s fine to use smart bulbs with dimmer switches which are communicating by RF (radio frequency) and do NOT directly cut the current to the bulbs, and there are in fact many switches designed for this purpose. Phillips hue has a dimmer switch, as you noted Sylvania has a dimmer switch, and there are others.
In addition, you can use any dimmer switch which smartthings can recognize and create a “virtual three-way“ where the dimmer switch sends its command to the hub and then the hub sends the command to the smart bulb. In these setups it doesn’t matter what protocol the switch and the bulb are using because they are not communicating directly to each other. You can have a zigbee dimmer switch in a virtual three-way with a Z wave smart bulb. Or a zwave dimmer switch in a virtual three-way with a Zigbee smart bulb. Or either in a virtual three-way with a Wi-Fi smart bulb. The only condition is that each of the individual devices has to be able to communicate with the hub. ( or your SmartThings account, in the case of Wi-Fi devices.)
Matching the protocol only matters if you want the switch to be able to control the bulbs even if the hub is not working.
It’s only discontinued in some countries, and even in the US, it’s not officially discontinued, it’s just “out of stock“ and there are still a few retailers that have some inventory.
In Canada, as of this writing Amazon still has some for sale by Amazon, not a third party.

Community FAQs are written by volunteer community members and are not necessarily kept 100% up-to-date at all times but usually catch up eventually.
In addition, that particular FAQ listed a number of other options, including Zooz and the Inovelli, so even if a few items are out of date there may still be valuable information there. You can always ask a question if something doesn’t make sense. 
The Zooz zen26 is not a dimmer model. It’s a plain on/off switch. It doesn’t dim anything. If you want to be able to dim from the wall switch then you need a different model.
First rule of home automation: “the model number matters.“
If you want Dimming, you should be looking at the Zooz zen27, which is the one I linked to in my first post above.
So the Zen27 dims via z-wave and not via direct connection? That’s the main thing I’m not finding a clear answer to in the manual.
It can do both. Can dim the connected load, or the load can be disabled and it can dim via an automation or via zwave direct association.
@Bmr4life this is the option that means the switch and the bulb don’t have to be the same protocol. So it can dim your Zigbee or WiFi smart bulbs by using the hub as the intermediary.
It shouldn’t if the setting is set to disable the internal dimmer, but I suppose it’s possible if that step is missed. Could also hot wire the load Instead of wiring it to the switch, but that might have some code violation issues.
Yeah, I don’t want to hot wire even though that means I could use just about any smart switch available.
I have a waooz-1 on the way. If that doesn’t work out well I’ll order the Zen27.
Just looked at the web page for these. Maybe not the ugliest thing I’ve ever seen, but right up there near the top. Zero spouse-acceptance-factor.
Yeah, its going in the kids playroom so not much care from her.
They’re not terrible, just big. And probably the cheapest Z wave Device you can get if you get them from zwaveproducts.com
They sell a two pack for 21.
And a five pack for $45.
At that price they cost less than most of the smart buttons, and they’re much more intuitive for guests as far as on and off.
That said, I’m not sure they work for dimming with smartthings. If they do, they probably need custom code. Out of the box, I think they’re two buttons.
I received it already. It requires custom code just to install it but it was shared publicly a few years ago.
