We bought a house recently that has a Pico dimmer switch that controls one of the lights. I can not turn off the lights or dime them now. Nothing happens. The light stays on. We were not told of any “system” or WiFi connected control in the house. I could send a pic of the dimmer but it says Lutron on it and has two rectangular buttons and in the middle it has two triangular buttons with a circle in the middle.

If I push and hold the buttons for ten seconds nothing happens.

There is a green light that sort of flutters for a second but that happens when I push any of the buttons.

Point me in a direction? Thanks.
