---
**Brand:** Aqara
**Price Range:** $25 - $99.98 across 16 retailers

## Pros
- Works without a neutral wire, making it suitable for a wider range of homes, especially older ones with outdated wiring.
- Reliable performance with a strong Zigbee connection, providing stable everyday use.
- Easy to install even for users without advanced electrical skills.
- Integrates well within the Aqara ecosystem, enhancing smart home control if you already own other Aqara devices.
- Stylish and modern design that fits well with various home interiors.
- Remote control functionality is flawless and responsive, especially over a Matter network with no noticeable lag.
- Compatible with Apple HomePod and can be easily paired via QR code, automatically added to the Apple Home app.
- Customization of the 3 buttons via Apple Home app allows various automation triggers.
- Works seamlessly with Home Assistant for more advanced smart home setups.
- Functions reliably with multiple dimmable bulb types, including incandescent, halogen, ELV, CFL, and many LED bulbs.

## Cons
- Significant integration issues with Alexa, especially with Thread/Matter and Zigbee devices not appearing or being unstable in Alexa’s device lists.
- Switching between Aqara hubs and other border routers (like Alexa or HomeKit native routers) can cause connectivity problems.
- Limited customization options when using Matter over Thread in Alexa and HomeKit — devices show up as basic lights with no advanced controls.
- Dimming functionality is not perfectly linear, which may be noticeable on some lighting setups like outdoor eaves.
- Physical manual controls can have delays or inconsistent responsiveness at times.
- Some users report flickering or unstable light levels, especially with certain LED bulbs like cornrow LEDs, which work fine on other dimmers.
- Wiring labels (L, L1, NOpt) are confusing and do not always align with standard electrician terminology, complicating installation.
- Troubleshooting to fix connectivity or flickering issues may require network key management or switching hubs.
- More expensive than some basic dimmers, reflecting its smart features but possibly off-putting if you don’t leverage the ecosystem.
