Every month or two someone asks how they can use the Lutron pico remote with SmartThings. Because these make really nice wall mount multi button control units.
There are some different ways to do it, but most require using a different server device as a “man in the middle” and it gets pretty complicated.
Unfortunately, the official SmartThings integration does not expose the pico button presses. 
The easiest way to do it for non-technical people is to use a Lutron Caseta dimmer pocket socket plug-in as a “proxy“ for the pico.
You set up the pico to control the dimmer in the Lutron app.
Since you will be able to see the dimmer in either smartthings or HomeKit, then you just trigger your events from the changes in the dimmer.
Note that you still have to have the Lutron smartbridge in order to get the integration with smartthings. But this method will work whether you have a smartthings/Aeotec hub or not, because the SmartThings/Lutron integration is cloud to cloud.
Obviously this adds additional cost since you have to have one dimmer for each pico, so more technical people will probably prefer one of the other methods like using hubitat as a “man in the middle,” but for non-technical people, having an easy way to do this may be worth the extra cost, especially since the Picos themselves are quite inexpensive. Or you can buy a bundle which has one pico and one pocket socket, those usually cost right around $50. Since the pocket socket by itself usually cost around $45, this is a good deal in that sense.
Here’s an article explaining exactly how to do all of this:
And here’s the product:
Home Depot and Lowe’s both usually carry these, so if you have gift cards or discounts there, you may also get a good price.
Again, The only advantage of using the pocket socket as the proxy is it’s just very easy to do and you don’t need any special technical knowledge.
Here again is the article on using the pocket socket as a proxy:
