Lutron question: With Caseta or RA2 Select, can you hold a Pico button to dim/brighten?

Not a Hubitat question exactly, but a Lutron system question...

I am coming from an Insteon system where I am accustomed to remotes supporting dim/brighten if you hold the appropriate button. I use this feature constantly.

Presumably the same sort of control is offered in the Lutron world of Pico remotes. I often see them used in place of a second dimmer switch, so it seems like this must be possible. Can anyone confirm that I can go from lights off to low lights by just holding a Pico button for a moment? I just don't want to make any poor assumptions before I buy in to a new system.

(If I go Lutron I am leaning towards RA2 Select, if it matters, but nothing is set in stone yet.)

Thx in advance!

Holding a button works to dim and brighten. Albeit separate buttons for dim and brighten.

If your talking about a 5 bottom R/L, yes holding raise or lower will increase or decrease from 0-100-0.

EDIT: I use RA 2 full, but I think @aaiyar uses Caseta and it should be standard across all Lutron platforms

Dead on target.

Fantastic, thanks guys.

Yes you can do this direct with the Pico configured within the Lutron system or you can expose the Pico to Hubitat and use it as a button controller.

For best results IF the Pico is only going to be used for the lighting control perform the configuration from the Lutron side and leave it out of Hubitat. This way it "just works" regardless of the state of the hub.


Makes sense. I think my plan is to configure lighting which should always "just work" with good speed in that way, but I may also use some Picos for stuff like mood lighting which can tolerate less speed or reliability.

Big talk since my Hubitat isn't even here yet!

Absolutely. This is why we all end up with so many Pico's!!! It's because of how versatile they are.

If you are building anything more than a very small system my recommendation is to skip RA2 Select and go for the the full RadioRA 2 system. The full RadioRA 2 system offers a few items that are worth the added expense IMO. 1) Access to seeTouch keypads. Better looking and more capable than Picos, only available in the full system 2) occupancy sensors usable in Hubitat. RA2 Select does not publish occupancy sensor activities to the Telnet interface, and 3) the physical dimmer controls are more configurable in the full system. RA2 Select locks the physical device control 'on' state to 100%. The full system 'on' state is configurable to a set level or previous level.

Some of those are nice features that I am used to from Insteon. Full RA2 is so flippin' expensive, though.

Price aside I thought full RA2 was only available to installers?

I'm pretty sure everything besides the Caséta/Lutron Smart Bridge system is only supposed to be available to installers, and that includes the Caséta Smart Bridge Pro (the kind of Bridge you'll need for Hubitat). You can sometimes find these new online in "regular" markets, but all are also easy to find on eBay or other secondary markets. I got a RA2 Main Repeater for something like USD $150, though I had to be patient and win an auction for that, and I think it was used or at least open-box. I just wanted to use their occupancy (motion) sensors on Hubitat, and this is the minimum you'll need for that; it's otherwise way overkill for what I'm doing.

If you're within the device limit, don't need RA2 features like keypads or occupancy sensors on Hubitat, then RA2 Select or Caséta would both work. Neither is exactly cheap (except the Picos that work on all of these systems), but Caséta hardware is less expensive. The downside is that (again, besides Picos), it's not compatible with RA2, whereas RA2 Select uses hardware that is all compatible with "full" RA2 should you choose to upgrade later. Just something to consider as you choose! (Oh, and "full" RA2 requires free online Lutron training for access to the Windows-only software you use to configure and add devices to the system; the rest of them allow all this from a mobile app.)

You can buy all the RadioRA 2 stuff from about any electronic supply house local or online. In fact, if you're buying a lot of stuff you should get quotes from more than 1 supplier. I've had great success from Hanks Electric ( Contact Paul Williemsen ( to get a quote.

Fascinating, thanks guys. Lots to think about.

Very true, but don't let this slow you down too much. The online training and "test" is a joke. I recommend following the curriculum (your browser must at-least play the complete video you might as well watch it!) and learning what they tell you. However in the end it's an open book test you can take as many times as you want (or write down the correct answers and take it again).

I went with RA full because I really wanted the hybrid keypads, but as mentioned above, it's a semi expensive "upgrade". You should certainly do your homework and decide if you want keypads or occupancy sensors and go from there.

Here's a comparison guide that will tell you exactly what does and does not work with each system. I found it helpful when I was deciding, I hope it helps you as well.

If you're interested in in depth learning of the system, Level 2 training is now available online (it used to be in person only). It's 2.5 days and the cost is $650 but you get a lot of equipment including a main repeater and connect bridge. The list of included equipment is:

1x RR-MAIN-REP-WH (main repeater)
1x CONNECT-BDG2-1 (connect bridge)
2x RRD-3LD-SW (lamp controller)
1x RR-15APS-1-SW (appliance switch)
1x RR-T5RL-SW (5 button table top keypad)
1x LRF2-OCR2B-P-WH (occupancy sensor)


Nice find! That's a pretty good deal considering what you get. I wish they had that around when I bought I would have grabbed it!

Huh. When I took the Level 2 in person last year, that was the equipment we trained on in the lab, but we didn't get to leave with any of it. :frowning:

OTOH, we did get a few good meals and a discount on the hotel room. :grinning:

If I do Select I’m already looking at $500 for less stuff in the starter kit... hmm.

Edit: then again this stuff is much much more expensive than Select. The 5 button keypad is $500-$750? $200 dimmers? Even if my quick price check is off by 100%... yikes!

The dimmers are the same between RadioRA 2 systems, so the same price. There are 2-3 dimmer models that you would want to look at. MSRP is $150-220 depending on the model you choose.

A 6 button hybrid keypad (most common for retrofits) is MSRP $440.

A RA2 Select Main Repeater is MSRP $249. A RadioRA 2 Main Repeater is $550 and Connect Bridge is $300. There is a Main Repeater + Bridge combo SKU for MSRP $770.

So if you went full RadioRA 2 right away the difference in MSRP is $770-$249= $521. But then you gain the upsides that I outlined in my first response.

As I said before, get a couple bids. Working with electrical supply houses is not like shopping at Home Depot or Amazon.


MSRP is a rip off, and you should be able to do much better. Below is a sales sheet from one of my Lutron orders (one has Select one is RA2 main repeater). Myself and a few other here have "dealer" accounts. If you go RA2 and need better pricing, I'm happy to pass on the pricing below if you cannot beat it else where. PM me if needed.

EDIT: images removed out of respect for other dealers pricing models. If anyone from the HE community wants parts I will pass on my cost (credit card fees, and hr cost applied additionally). I am not high volume and even my prices can be beat if you try hard enough. PM for details if needed.

Rough numbers

RA Main Repeater - $475
Select MR - $175
Keypads - $300
Dimmer - $125
