New plugin brings Rithum’s touchscreen control to RadioRA 3, and connects RadioRA 3 into the rest of the Rithum smart home platform — alongside full climate control, multiroom audio, SIP intercoms and CCTV.
LONDON, UK — 5th August 2026 — Rithum and Lutron Electronics announced integrated support for Lutron® RadioRA 3® inside the Rithum smart home platform, delivered through a new Rithum Pro Plugin. The integration brings RadioRA 3 lighting and Sivoia motorised shading into Rithum — giving RadioRA 3 installations a touchscreen control point at the wall plus full climate control (with systems like Heatmiser, CoolAutomation and Rithum’s built-in Rithum Stat thermostat), multiroom audio, and broad SIP intercom and CCTV support.
“RadioRA 3 has been one of the most-requested integrations from our installer community since it launched, and we’re proud to deliver it,” said Ryan Ovens, CEO at Rithum. “Lutron’s keypads provide elegant, intuitive control. What Rithum adds is a sleek touchscreen control point on the wall, fine dimming when you want it, and a full smart home platform around RadioRA 3 — climate, audio, intercoms and CCTV all in the same environment. Lutron keypads and Rithum touchscreens will work together to deliver both dedicated lighting control and whole-home smart home management.”
What the Plugin Adds for RadioRA 3 Installs
Lutron keypads have long been a hallmark of residential lighting — a beautiful, tactile way to recall scenes on the wall. The Rithum Pro Plugin sits alongside them, adding a visual touchscreen layer to RadioRA 3 installs: fine dimming, shade positioning and dynamic scene selection, all from the same wall.
Alongside RadioRA 3 lighting and Lutron shading, the Rithum Switch controls full climate — setpoints, schedules and zoning — via Heatmiser, CoolAutomation and Rithum’s built-in Rithum Stat thermostat; multiroom audio from systems like Sonos, BluOS and WiiM; and broad SIP intercom and CCTV support from a wide range of manufacturers. Macro scenes tie it together: one tap can trigger a RadioRA 3 lighting scene alongside a shade move, a temperature change and music in the room. RadioRA 3 keeps doing what it does best; Rithum extends what installers and homeowners can do with it — from one place on the wall.
Hubless, and Quick to Configure
On the Rithum side, the system is hubless: the processor sits inside every Rithum Switch and Rithum Switch Pro, alongside the touchscreen. Configuration is just as light. When paired with a RadioRA 3 system, Rithum pulls existing scenes, circuits, zones and shades directly from the Lutron processor — and stays in sync. Add a zone, rename a scene or re-tune a dimming curve, and Rithum reflects it automatically. What might have been hours of duplicate setup becomes a matter of minutes.
“Rithum offers a smart home platform where RadioRA 3 can sit naturally alongside full climate, audio, intercom and CCTV control — exactly the kind of installer experience we want RadioRA 3 specified into,” said Ben Bard, Vice President, Luxury Residential at Lutron Electronics. “We’re pleased to welcome them into the RadioRA 3 ecosystem.”
