the Lutron Picos are invisible to smartthings through the official integration. You can still use them through the Lutron app to control other Lutron switches that you have, but you can’t use them for anything else.
So if you just want to use them as the auxiliary switch in a three-way with a Lutron Caseta master switch, just add your lutron smart bridge and the master switch to SmartThings, then use the Lutron app to match the pico to the master and you should be all set. You won’t see the pico listed in your SmartThings app, but the three-way set up will work just fine.
to get more functionality
There are three methods that some community members use to get additional options from the picos, but each one will require adding yet more devices.
One) use a Lutron Caseta plug-in dimmer as a proxy
This is the simplest method but also the most limited. And you will need one plug-in dimmer for each pico.
- use a raspberry pi or other device as a server and then follow the instructions in the following thread. This works well but requires significant technical knowledge. This will be limited to a single Lutron smartbridge pro, But you will be able to see each pico individually.
- Use a Hubitat And set up proxy devices.
Hubitat is a hub similar to smart things, but happens to have a really great local Lutron integration. And it will let you use multiple Lutron Smartbridge pros, So it’s especially good for people who will have more than 75 Lutron devices total. But again, you will need a pretty strong technical background to get this all set up.
So those are the choices. It’s not elegant, but any of these will work if you really want to use the picos with smartthings.
