Shelly Multicolor Bulb E27 Gen3 Review: An Open, Locally Controlled RGBW Bulb for Automation Builders
The Shelly Multicolor Bulb E27 Gen3 is a cheap, hub-free RGBW bulb aimed at people who automate their lighting rather than just switch it. It covers the basics well (millions of colors, a 2700-6500K tunable white range, 806 lumens, smooth dimming and a configurable power-on state) and then adds what almost no rival bulb at this price offers: local scripting, MQTT, REST and webhooks, plus an official Home Assistant integration that owners confirm works. The trade-offs are real, though: it is a Wi-Fi-only device with no Matter certification and therefore no route into Apple Home, it has no pre-programmed dynamic light effects, and the Shelly app is the part buyers complain about most. For a DIY smart home it is excellent value; for someone who wants a bulb that pairs in one tap and cycles party colors out of the box, it is the wrong pick.

Who is the Shelly Multicolor Bulb E27 Gen3 for?
This is a bulb for people who want their lighting inside an automation system, not just on a phone. It screws into any standard E27 fitting, connects straight to 2.4GHz Wi-Fi with no hub or gateway, and exposes the full Shelly Gen3 toolkit: scripting, MQTT, a REST API, webhooks and 20 schedules, along with local actions and auto on/off timers. That makes it a natural fit for a Home Assistant or Shelly-based setup, and several owners bought it precisely to sit alongside gear they already run, one of them reporting that he simply connected it to Home Assistant and controls it from there, another pairing it with a Shelly 1 Gen4 to drive open and close scenes. It doubles as a BLE gateway and a Wi-Fi range extender, so in a house already full of Shelly devices it earns its place twice over. Someone who just wants a colored bulb for a lamp will find it does that too, at a price that is hard to argue with, but they will be paying for capabilities they never touch.
What buyers love
The recurring positive is simply that it works and keeps working: owners describe setup going smoothly and the light output being exactly what they expected, with short verdicts along the lines of it functioning flawlessly. The Home Assistant angle is the standout praise, and it lines up with the spec sheet: the official Shelly integration covers all four device generations, so the bulb turns up as a local entity rather than a cloud one. Buyers already invested in Shelly gear also single out how naturally it slots into an existing setup, using it in scenes triggered by other Shelly devices. The light itself draws no complaints on quality: the full RGB range plus a 2700-6500K white range, a CRI above 80 and 806 lumens from 8.5W are enough for both everyday room lighting and colored ambience, and the bulb supports smooth dimming with a configurable transition duration rather than snapping between levels.
What to know before you buy
Two things trip people up. The first is the app: more than one buyer found getting the bulb onto Wi-Fi a struggle and described the Shelly app as complex and unintuitive, with one Italian owner spending a whole day on it and considering a return. Shelly's software is built around configurability, and that shows. The second is what this generation dropped. One German owner points out that the bulb can only be set to fixed colors now, and that the automatic color change and meteor effect that earlier Shelly bulbs offered are no longer selectable in the app, which matches the specification: neither the knowledge base nor the bulb's own component API documents any pre-programmed lighting effect, so dynamic scenes have to be built by hand as schedules or scripts. On the platform side, the bulb is not Matter certified, and Shelly's own forum confirmed that both Gen3 bulbs currently ship without Matter support, so there is no route into Apple Home at all; Alexa, Google Home, SmartThings and Home Assistant are the supported paths. Connectivity is 2.4GHz Wi-Fi plus Bluetooth 4.2 only, with no Zigbee, Thread or Z-Wave. Finally, a handful of buyers received a faulty unit: one found one of three bulbs dead, another got a bulb that would not join the network in a package that had already been opened, and a third had a dead bulb refunded after contacting Amazon. Third-party tooling is also still catching up, with one owner reporting the Gen3 bulb does not work with the ioBroker adapter.
Is the Shelly Multicolor Bulb E27 Gen3 worth it?
At this price it is one of the cheapest ways to put a genuinely scriptable light into a home, and that is the whole argument for it. Nothing else in the budget tier hands you MQTT, a REST API, webhooks and on-device scripting in a bulb, and the official Home Assistant integration means none of that depends on a vendor cloud staying online. Set against that, you give up Matter and Apple Home, you give up canned color effects, and you accept an app that rewards patience. A two year warranty and Shelly's long record with local control make the gamble a reasonable one. Buy it if the bulb is going to be part of an automation; look at a Matter or HomeKit bulb instead if what you want is a light that any ecosystem can adopt in a tap.
Frequently asked questions
Does the Shelly Multicolor Bulb E27 Gen3 need a hub?
No. It connects straight to a 2.4GHz Wi-Fi network and can be controlled locally, from the Shelly Smart Control app or from a third-party system, with no gateway or bridge in between. Bluetooth 4.2 is used for onboarding and for control from Shelly BLU remotes and buttons.
Does it work with Alexa, Google Home and SmartThings?
Yes. Shelly documents Amazon Alexa capabilities, Google Smart Home traits and Samsung SmartThings capabilities for this bulb, so all three give voice control and automation.
Does it work with Apple Home or Matter?
No. The bulb is not Matter certified, no Shelly bulb appears in the CSA certified product database, and Shelly's own forum confirmed that the Gen3 bulbs ship without Matter support. Since Shelly does not offer a native Apple profile either, there is no way to add it to the Home app.
Can I use it with Home Assistant?
Yes. The official Home Assistant Shelly integration states that all four Shelly device generations are supported, which makes this a locally controlled entity rather than a cloud one, and owners report running it that way.
How bright is it, and what fitting does it use?
It is an A60 bulb with a standard E27 base, drawing 8.5W for up to 806 lumens, with a 200 degree beam angle, a CRI above 80 and a rated life of 15000 hours.
Does it remember its state after a power cut?
Yes. The power-on behaviour is configurable, and the bulb's light component accepts off, on or restore last as the state to apply when power returns.
