Shelly is one of the few lighting brands with official Works with Home Assistant certification, and the Duo Gen3 behaves like all Shelly kit: fully local Wi-Fi, instant push updates, even MQTT if you prefer. It's tunable white only — no colour — so if you want RGB scenes, WiZ or IKEA's KAJPLATS bulbs are cheaper and simpler. What the Duo offers instead: Wi-Fi rather than Matter/Zigbee, a genuine Bluetooth proxy for battery sensors (it's mains-powered), and on-device scripts that keep circadian schedules running through a Home Assistant outage. Best for tinkerers already running Shelly gear, not casual buyers who just want a warm-white bulb that dims from an app.
