Step-by-Step Solution
Confirm Dimmer Works
Turn the Caseta Diva dimmer on and off at the main location. Ensure it responds before pairing the Pico.
Put Dimmer in Pairing Mode
Press and hold the dimmer control button until the LED indicator flashes. This opens pairing mode for a Pico remote.
Pair the Pico
Hold the Pico off button for 10 seconds until the dimmer flashes. The dimmer will respond to confirm pairing.
Mount the Pico
Install the Pico in a wall plate using the Lutron adapter or in a surface mount kit. Align it to match existing switches.
Test Both Locations
Toggle and dim from both the dimmer and the Pico to confirm two-location control.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If flickering only happens on dimming, the issue is almost always the dimmer's minimum-load setting, not the bulb — it's drawing less current than the dimmer expects.
Label the Pico with the room name before mounting. It helps future troubleshooting and room changes.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
