Sonoff B05-BL-A60 Review: A Budget RGB Bulb That Wins Over Home Assistant Fans
Vivid tunable color and broad voice-assistant support at a low price, held back by 2.4GHz-only WiFi and no power-outage memory.
The Sonoff B05-BL-A60 is a full-color, dimmable E27 smart bulb that pairs quickly with the eWeLink app and works directly with Alexa, Google Home, SmartThings and Home Assistant. Buyers consistently praise the rich color range and easy day-to-day control, while the recurring gripes are a WiFi-only connection that can be picky about long router passwords and the lack of a configurable power-on behavior after an outage. For the price, it is a solid pick for anyone building out a DIY or voice-controlled lighting setup rather than an Apple HomeKit household.

Who is the Sonoff B05-BL-A60 for?
This bulb fits buyers who want an affordable, full-color E27 replacement they can control from the eWeLink app or by voice through Alexa or Google Home. Its 2700-6500K tunable white range plus full RGB color makes it a favorite for mood lighting, and several reviewers specifically picked it as a dimmable night light, using warm or red tones at very low brightness for a baby's or child's room. It also draws a lot of interest from Home Assistant and other DIY automation users thanks to the community SonoffLAN integration, and from shoppers who already own other Sonoff gear and want to keep everything in one ecosystem and app.
What buyers love
The most repeated praise is how easy setup is: buyers across several countries describe pairing the bulb to the app and to Alexa or Google Home in minutes, matching the bulb's positive marks for Google Home, Alexa, SmartThings and IFTTT integration. The color quality also stands out; owners highlight the wide, smooth range between warm and cool white plus vivid RGB colors, along with dimmability and the built-in dynamic lighting scenes for switching moods. Several long-time Sonoff customers also call out reliable reconnection: bulbs picking their WiFi and Alexa link back up quickly and remembering their last color and brightness after being unpowered for a while.
What to know before you buy
The bulb only connects over 2.4GHz WiFi, with no Bluetooth, Zigbee, Z-Wave, Thread or 5GHz support, and a recurring complaint is that some routers using long (24-character) WiFi passwords fail to pair until the password is shortened or simplified. There is no Apple HomeKit or Matter support, so it is not a fit for an Apple-first smart home. A handful of buyers also ran into friction signing up for or verifying the required eWeLink account. Because the bulb has no configurable power-off memory, several reviewers note it turns back on by itself after a power outage with no setting to keep it off, and Home Assistant support comes through the community-maintained SonoffLAN project rather than an official built-in integration, which tripped up at least one buyer expecting native recognition. A small minority also reported a bulb dying or losing its pairing after a few weeks or months of use, or the light running noticeably warm.
Is the Sonoff B05-BL-A60 worth it?
Given its low price point, the Sonoff B05-BL-A60 delivers more than expected: strong color quality, a standard E27 fit for existing fixtures, and direct support for the major voice assistants plus IFTTT and Home Assistant automations. The trade-offs, a WiFi-only connection, no HomeKit or Matter, and no power-loss memory, are the kind of limitations typical of budget smart bulbs, and most buyers rate the overall experience positively despite them. It is a sensible choice for anyone prioritizing color and voice control on a budget over Apple ecosystem support or advanced mesh networking.
