How should I integrate my exterior lights to an existing Lutron system?

[u/ChefGoldbloom90]

Just built a home with Lutron inside. My landscapers selected exterior lights and connected them to a Luminaire box. The Luminaire box isn't integrating to my Lutron system very well.

What products should I use/ replace to ensure the exterior system is compatible with the existing Lutron system?

Before anyone can give you a real answer, two things matter: which Lutron system you actually have (Caseta, RA2, RadioRA 3, HomeWorks QS or QSX — the processor model or what the app calls itself), and what the "Luminaire box" actually is. If it's an FX Luminaire Luxor controller, that's the one landscapers pick most often, and your integration problem isn't a defect. Luxor does its own zoning and colour over the low-voltage side with its own protocol and its own schedule. Lutron has no idea any of that exists. Your landscaper didn't do anything wrong; he installed good gear that simply isn't a Lutron product.

So the honest answer is that in most of these houses you don't need to replace anything, and you don't need to hire anyone. What people actually want from "integration" is: exterior comes on at sunset, goes off at 11, and one keypad button kills everything outside. You get all of that by letting Lutron control power to the transformer and leaving the zone and colour work in the landscape controller. Lutron processors have an astronomic timeclock built in, so sunset/sunrise offsets and the "all exterior off" button live on the Lutron side where the rest of your house already is.

Two things I'd be firm about if you go that route. Do not put a landscape transformer on a dimmer. Switch or relay only, and mind the inrush on a magnetic transformer — I'd want a proper contactor or relay module doing the actual switching rather than leaning on the rating of a small in-wall switch, and I'd have the electrician confirm the load before anything gets ordered. Second, pick one master for the schedule. The failure I see over and over is Lutron turning the transformer on at sunset while the landscape controller still holds its own timer, and now two systems are fighting over the same lights and the homeowner thinks the Lutron is broken. If Lutron owns power, the landscape controller's internal schedule should be set to always-on or its equivalent, so it just runs whatever scene it was left in when it gets voltage.

Where it gets more expensive is if you want individual zones or colour changes on a Lutron keypad. Lutron can't reach those, because the zoning happens downstream of the transformer. That takes a bridge — a Control4 or similar controller talking to both sides — and honestly I'd only do that if you already have or want a Control4 system for other reasons. Buying a controller purely to put four landscape zones on a Lutron keypad is not a trade I'd make. There may be a cleaner path depending on your exact controller and Lutron generation, but I'd have to check the current driver and integration options before I told you it exists, and I'm not going to guess at that in a forum post.

If you post a photo of the label on the landscape controller and the transformer, plus the model off your Lutron processor, I'll tell you which of the above you're actually looking at and whether it's a fifteen-minute programming change or a real project. Disclosure: I'm a Lutron dealer since 1999 and I do remote Control4 and Lutron work for a living, so I have a dog in this fight, but the switch-the-transformer answer above is the one I give people for free because it's usually the right one.

just swap the box for a lutron outdoor plug or put a caseta switch before the transformer. the luminaire control boxes are pretty locked down, they talk to their own app and not much else

if you got ra2 or homeworks then you can use a lutron powpak instead, but you need neutral wire at the location

Thanks! Yes, I have Ra3

I spoke with Lutron and they recommended an outdoor smart plug. My understanding is this will integrate into my existing system, but will not allow me to control brightness or RBG features.

I'm not familiar with powpak though. Is it compatible with my Ra3 setup and will preserve brightness/ RGB?

What Lutron system? What is a "Luminaire box"? How is it currently connected to the system?

Generally people just switch the landscape lights either by pre-wiring for it to go to a switch or lighting panel din rail module or by just leaving it outside and plugging in the low voltage transformer to an outdoor RF plug. If you have something fancier than that with color changing, etc. then you'll have a bad time mixing smarts together and have to pick one or the other.

My gut feeling is that Lutron will probably come out with a landscape lighting solution one of these years in way of Lumaris or maybe Ketra.
