Legrand radiant vs. Lutron Caseta

[JDRoberts]

Both are good systems, but the LeGrand radiant line is intended to work with their own Intuity home automation platform and there is no integration with SmartThings at all.

Lutron offers the SmartBridge ( note: for technical reasons, this is a bridge, not a hub, just like the Philips Hue Bridge). With the SmartBridge, you can have an official Lutron Caseta integration with SmartThings, as well as with IFTTT, Amazon Alexa, Google Home, and a number of other partners.

Again, they are both good systems, but if you get radiant then you will be using their Intuity platform. Not SmartThings. Legrand Intuity uses a manufacturer proprietary profile which is not compatible with anything else.

FAQ: Zigbee Application Profiles, or why not all zigbee devices work with SmartThings

Zigbee is always zigbee, but the standard allows for different "profiles,"including manufacturer proprietary ones. [image] These are not all able to communicate with each other, they don’t even use the same addressing schemes. SmartThings uses the Zigbee Home Automation profile (ZHA 1.2) and part of the Zigbee 3.0 profile. Devices using other zigbee profiles may be able to join to the network, but their communications may not be understood, or they may frequently drop off because they don’t receive a handshake message they are expecting. There a lot of different ways to explain this, but I think one of the easiest is to think of zigbee as a post office and the different profiles as different languages. The outside envelope for different messages may look similar, have a specific format…

Lutron also uses a proprietary protocol, but they offer their SmartBridge product to allow integration with many other systems.
