Official Lutron Caseta Support in SmartThings (Beginning March 2017)

Thanks for the tipoff on the starter kit; I’ll need both or all of these anyway. I have a friend who can 3D print me the wall mount backplate for the Pico. THANKS!

Hello. First, thanks for the great insight in this thread. This is my first post to this forum. By way of background, I have been involved in DIY home automation for 10+ years. Way back, I first started with CQC (Charmed Quark Controller - anyone remember that?) and X10. I then moved to an ISY99 and Insteon wall switches. For the past few years, I have been running an ISY994i with the Insteon switches, some Hue bulbs, and 4 wall-mounted iPads (using the magnetic induction charging Launchport mounts), using SimpleControl (formally RoomieRemote) to control the ISY994, and using probably 7 or 8 Global Cache IP-IR or IP-Serial boxes to control AV systems throughout the house. This has worked well for me the past few years, despite the inherent lack of reliability for the aging Insteon / powerline protocol.

The upgrade of Google Now to Google Assistant on my Galaxy S8+ opened my eyes to the integration of Home Control and voice activated home control. My eyes really lit-up when I realized that IoT is no longer theoretical - it is here.

I may jump into the mix here and dive into the deep end with a Raspberry Pi, Caseta and a few hubs. I never heard of a Node.js script but apparently I need to learn more. I have spent the better part of a week researching and have a few questions regarding the last few posts.

  1. Regarding the Caseta Smart Hub vs. Smart Hub Pro, it seems as if the Smart Hub Pro is harder to find on Amazon and it also has limited stock, is not available on Prime, etc. However the regular Caseta Hub is available on Prime. Is the Caseta Smart Hub Pro discontinued or about to be discontinued or depreciated? If I am going to jump in, I would get the Pro so realize all of the benefits of the Pico to control Hue lights.

  2. Regarding Smarthings Hub, which would be the other hub I would purchase, any ideas on integrating the existing AV Global Cache devices? I am assuming I would control my SimpleControl directly from the ST hub, and I think this means getting a third (!) hub (the “Simple Hub” plus a license - and combined that’s an extra $250) to make this work. I don’t want to hijack this thread on this topic - but just curious if anyone has any thoughts here. (actually it would be a 4th hub if you count the Hue hub).

  3. I also see Lutron has the Lutron RA2 system. Apparently this will be Google Assistant ready soon. However, am I right to assume that Google Assistant ready and ST ready are 2 separate animals? Is there any benefit to RA2 over Caseta? The extent of my knowledge thus far seems to point to Caseta as a more DIY friendly system, particularly with regard to the community Raspberry Pi integration of Picos.

Ultimately, I want to replace my Insteon switches and upgrade to IoT but this technology is unfolding fast. I love the Pico form factor and want to expand on my SimpleControl system as well as lighting. Perhaps a Pico to turn on a TV, adjust lights, set a channel, etc.

That’s it for now. Happy to be a new member here.



(BTW, the Lutron devices are technically “bridges” not “hubs,” hence the name. :sunglasses:)

.1. The Lutron “SmartBridge pro” is intended for their professional installer channel. It’s not usually sold at individual retail. That’s why it’s hard to find. I believe they actually sell more of these then the DIY “SmartBridge” models. So it’s not going away anytime soon, it’s just that you’re not going to see it on Amazon unless an installer is getting rid of some excess stock. Or you go to one of the wholesalers who will sell direct to the public.

.2. I suggest you start a new thread under projects to keep from hijacking this one and so you can get individualized responses based on your own set up. That way we can go deep into the various issues about A/V Control. :musical_score::film_strip:

.3. You were absolutely correct: Google assistant integration is a whole different issue than SmartThings integration. At The present time Lutron’s RA2 System is not part of the official SmartThings cloud to cloud integration. It may be able to work with the community “man in the middle” integration, but you should take that discussion to that thread, along with the pico discussions . You’ll get the quickest answers there. :sunglasses:

Thanks for the quick response!

I have the same issue. Love my Lutron setup and have many scenes setup that dim different switches to different levels. I can’t seem to have SmartThings trigger a Lutron Scene. I have to have SmartThings control each dimmer and the built in routines force me to set multiple dimmers to the same value.

I’m trying to do this in the context of my exterior lights (2 x pot lights + 1 set of bright LED porch lights). I want to two pot lights set to 50% and LED Porch Light dimmed to 10%. SmartThings forces me to pick a single dimmer percentage where as Lutron scenes work perfectly. Help!

If you have a scene you like, you can create a virtual switch and have that switch coming on trigger the Lutron scene through the Lutron IFTTT channel. That may introduce some additional lag, so it might work for some use cases but not others.

Once you create a virtual switch, it will show up on the list of your switches in SmartThings, so you can use it in a routine or the official SmartLighting feature.

Alternatively, you should be able to use webcore and set the different switches at different dim levels. I think that will work with Lutron. (@ady624 would know). Setup is more complex, but there are lots of community members who will be glad to help you, and it gives you a lot more options.

FAQ: What is WebCoRE? (And what was CoRE?)

The third alternative is to create one automation for each dimmer, using the same trigger condition for each, which is annoying but will work.


I’m a newbie so i’m struggling with the fact I need to rely on the “When Things Quiet Down” setting in Routines. I’m using the Motion sensor on my Ring Pro to trigger the outdoor lights on 100% (somebody approaching house) via Caseta. Then when Things Quiet Down for 15 minutes, I want the lights to dim down to a mix of 10 - 50%. Will IFTT help with this?

For now I have created two separate routines (to match the two different dimmer settings). Looks to be working but clumsy to maintain.

IFTT doesn’t seem to integrate with the “If things Quiet Down” capability.

So many ways to skin a cat! love to just keep it simple. lol

Correct, unfortunately there is no “when things quiet down” setting for the SmartThings IFTTT channel.

What you can do is what we call a “daisy chain.” You use Smart Lighting to have when things quiet down (motion stops) turn on a virtual switch and have that virtual switch coming on Be the “if” in your IFTTT applet.

You’ll also need to have a separate smart lighting automation use a power allowance on the virtual switch so that it turns itself off after one minute so it will be ready to use again.

If that all sounds clunky and complicated, it is. :disappointed_relieved: So you might want to just go ahead and start using webcore. You’ll be able to put all of your trigger conditions and all your lights into one rule (which webcore calls a “piston”). So all the set up is a little more complicated, the maintenance is a lot easier to keep track of if you ever want to change any of the conditions.

I just noticed that if I adjust my Lutron lights and fans with the switch or the caseta app, it’s not updating in the ST app. I can manually refresh the devices in ST and they’ll update. And I can manually adjust them in the ST app too.

I’m not 100% sure how recently this started but I noticed it tonight.

@ZachFromLutron Any idea why this is?

We experienced an issue last night between 8:30pm and 5:30am that affected third party integration through cloud-based services, like SmartThings. During this time SmartThings status updates were down or intermittent This issue has been resolved, but please let us know if you continue to experience this behavior. We apologize for the inconvenience.


Thanks for the clarification, I will check when I get home from work.

@ZachFromLutron I’m still getting the same behavior. I’m able to control my Lutron dimmers and switches from the ST app but any changes I make at the wall switch or in the caseta app have to be manually refreshed in the ST app.

Anyone experiencing any problems adding devices? We completed a kitchen remodel so there are at least 8 lutron switches that are not in smartthings. Using the lutron caseta connect the Device discovery shows no new switches and it’s like the discovery status updates instantly, like it’s not running.

I contacted support who suggested I add and remove the smartapp and start over but that means that existing automations will need to be removed.

I haven’t contacted Lutron support, I thought perhaps removing the smartthings authorization and adding again would trigger discovery. But I don’t see a setting in the lutron app to remove existing authorizations.


Is this a two way integration? I’m currently running Homebridge on a Raspberry Pi but would love a better way to add Homekit compatibility to my SmartThings setup.

To ask another way. If I add a Caseta Wireless Smart Bridge to my home network and integrate with SmartThings will I be able to see my SmartThings devices in my Apple Home app?

If you mean the official Caseta/SmartThings integration, it’s cloud to cloud, but it does not cause the SmartThings devices to show up as HomeKit devices. They don’t belong to the Caseta bridge, it’s just that the SmartThings cloud can talk to the Caseta cloud.

It’s two way in the sense that The Lutron bridge will report events over to the SmartThings cloud even if they were not initiated by SmartThings. But smartthings-controlled devices do not show up in the Caseta app and cannot be added to schedules created in the Caseta app.

Bummer, thanks.

Can I hook up one of these switches to not control the power? Basically in my spare bedrooms, I have fans with lights in each of them. I don’t want to control the fan part, but I do want to control the light part. Can I hard wire the fan behind the switch so it has constant power, then branch off the hot into a Caseta switch making it a smart switch that doesn’t control physical power? Then I can put smart bulbs in the fan and set up ST to that when this switch is on, it turns the bulbs on and off?

I have a bunch of these casita switches sitting around that I’d like to use and not buy any additional switches. I know I’ve hooked up one of the GE smart switches this way and it works, but I didn’t know if these work the same way or not.

Does “at the moment” imply this may change, or that it is being actively worked on between SmartThings and Lutron? I have begun swapping out switches for Caseta switches in our new house, but unfortunately only realized today that ST will only support a single bridge (i.e., 50 switches). I’d love to know if this is a limitation that may be removed in the near-ish future.

Hi Chris, I will check with Lutron to see if this is on their roadmap!


Any updates on multiple bridges?
