On a tangent, I forgot how much of a pain it is to sync up Caseta gear to each other (not just to Wink). For reference (mostly my own in the future, when I forget haha), here is what I did: (this is just for pairing a Caseta switch to a Pico remote, not to a Wink Hub)
1. Reset the Pico remote to factory:
a. Tap the On (or Off, you choose) button 3 times, but hold it down on the last press.
b. You will first see the LED go off (happens quickly). Keep holding until the LED comes back on - then release the button.
c. Quickly (while the LED is back on) & firmly triple-tap the On (or Off) button again (distinct TAP, TAP, TAP) - do not hold this time
You can test to make sure it works by trying to turn the light on or off. If it still responds to the remote, try again - it can take a few tries to get the timing down.
2. Reset the Caseta switch to factory:
a. Tap the On button 3 times, but hold it down on the last press until the vertical LED strip starts racing up & down
b. While the LED's are racing, quickly & firmly tap the On button 3 times (do not hold). If you are successful, the lightbulb will do 3 things, in this order:
1) Blink 3 times
2) Shut the lightbulb off for a few seconds
3) Turn the lightbulb back on
The timing can be tricky with this procedure, so you may have to do it a few times. You will know you are successful (1) when it does the sequence listed above, and (2) when it stops responding to your Pico remotes.
3. Put the Caseta switch into pairing mode:
a. Press & hold the Off button until the entire vertical LED strip starts blinking. Blinking (all of them at once - not just one at a time racing up & down) means it is ready to be paired to a Pico remote.
4. Pair the Pico remote to the Caseta switch:
a. Press & hold the Off button on the Pico remote until the lightbulb starts to blink. It will blink the lightbulb 3 times to confirm successful pairing - you can let go of the button when it does this. Test the remote to make sure it works!
Note: You can pair up to 10 Pico remotes to a single Caseta (don't reset the Caseta to factory for additional remotes! Just put it into pairing mode, step #3). You can also get tricky by using a Lutron Hub to control groups, and also step it up by using a 4-button Pico remote:

Also, to set the middle round "Favorites" button lighting level on the Pico remote: set the light to the desired level, hold down the button, and wait for the vertical LED strip on the Caseta switch to blink twice.
