Is Lutron Casetta mostly for households that have neutrals? Most of my switches have no neutral. Only dimmer I have is for the under counter lights.
There are some options for Caseta dimmers and switches that don’t require a neutral wire.

Long story short, smart no-neutral options are most commonly dimmers (versus on/off switches). Caseta is no exception.
Caeta's latest (Diva-style) dimmer is no-neutral and gets good reviews. Their on/off switches are almost all neutral-required (just one excepton that I'm aware of).
You mentioned under-cabinet lights - those often have a unique dimming requirement that may not be compatible with some smart dimmers (which are typically bulb-oriented, for lack of a better term in an effort to use plain language here)... Bottomline -- just research your under-cab light's dimming requirements against whatever switch/dimmer you are considering to ensure compatibility.

Thanks for responding. For me, it is a question if I want to switch over to the Caddilac for a few more locations and the wife wondering what the heck do we need this. LOL
PD-5WS-DV and PD-5S-DV are on/off switches that don’t require a neutral.
Edit: current prices for them appear to be rough on the wallet though.

Caseta's new Diva dimmers are defitely worth considering -- it's a more traditional form factor compared to their previous styles, and it can (for all intents and purposes) function as an off/off switch in most circumstances if you're not keen on doing much dimming.
Sometimes you absolutely do need an no-kidding on/off switch (e.g. switch controls an outlet, fan/motor load etc), but if a smart dimmer can work, those are often easier & cheaper to find.
Another option I'd highly recommnd looking at is Inovelli's new Blue -- it's zigbee 3.0, and can be used as a switch** or dimmer and with or w/out neutral -- it's an impressive device.
** Edit - good correction about switch capability by @coreystup a couple posts below
Lutron does make a Caseta switch specifically designed for low voltage under-cabinet lights but I think it does require a neutral
Actually it doesn't really have a switch option. Originally I think it was supposed to have a relay but they repurposed that for 3 way support. The load always goes thru the MOSFET so you need a compatible load if expecting true on off relay style control.
I only realized this after I planned on using blues for some ballast controlled lights.

Good catch! I forgot about that since I don't have a placement where that's biting me.
Well, I suppose a good takeaway here for OP is that there's no perfect do-everything switch/dimmer out there, so doing compatibility research ahead of time will help save some fist-shaking later.
