Turning the switch off makes it not hot.

Make sure the dimmer you are using is compatible with the lights and that the lights are actually rated for dimmers.

This. And also make sure you aren’t overloading it. Dimmers usually have a max wattage rating.

I guess I'll swap the dimmer with a regular lutron switch

Reduce the load on it. I have soffit lights hooked to caseta, maybe 10 bulbs. Switched them to LED and it's much cooler.

Probably overloading it. Wiring looks ok.

Looks like a lutron dimmer. Can you post the model number?
Old or just installed?
Recently changed bulbs?
Some of those are only compatible with certain styles or bulbs and certain wattages.

LED is far less likely to do this
My father in law has a great room that has like 14 BR40 bulbs on one dimmer. They were all incandescent at one point. Dimmer was warm. Swapped it up to my favorite (Philips br40 with warm glow) and it’s cool. He did eventually swap that dimmer too a Caseta, but it was a standard paddle dimmer with a little embedded night light (what I thought may have been the culprit but wasn’t) when he first bought the place.

Not to be repetitive OP, but I'd bet dinner it's overloaded. I just installed an entire house worth of Lutron switches and had the problem with my garage lights. If it's a standard Lutron dimmer, their load capacities aren't super high. Lutron has some higher capacity switches (their standard paddle/decora switch is higher capacity). You can either go that route or switch to LED.

In proper installations. In cases where the dimmer isn't rated for LED's or the bulbs aren't dimmable then they absolutely will have issues and heat can be one of them. Lot of people slap in LED's on old dimmer switches without checking.
