FAQ on operating the Aqara H1 WS-EUK01 No-Neutral Smart Switch
Aqara H1 WS-EUK01/02/03/04 — power, network type, and neutral requirements
The no-neutral version (WS-EUK01/02) is wired in series with the live conductor and does not require a neutral; the version with neutral (WS-EUK03/04) requires N to be connected and provides additional functions. Ratings: 100–250 V~, 50/60 Hz, up to 8 A (resistive load), max. 2000 W. For correct operation of the no-neutral model, a minimum total load is required: for LED — at least 9 W; with lower power, flicker may occur. A capacitor is usually not needed.
Compatibility with wall boxes and installation of Aqara H1
H1 series switches are compatible with round and square wall boxes; the distance between centers when installing several devices must be at least 86 mm. Mounting hole spacing is 60 mm. Overall front dimensions: ~86 x 86 x 37.55 mm (H1 — frameless format).
Can Aqara H1 be used as a regular switch without a smart home?
Yes. Wired H1 models operate locally as conventional switches even without the Internet, Wi-Fi, or connections to apps or hubs; remote functions are not available in this mode.
Supported protocols and hubs for Aqara H1
H1 devices use Zigbee 3.0. For operation in the Aqara Home app and Apple HomeKit, an Aqara hub is required (region — Russia); Matter over Bridge is supported via a compatible Aqara hub. Direct integration is possible with Yandex Stations/hub with Zigbee and the Sber “Salut” hub. Integration with Mi Home/SmartThings/third-party Zigbee hubs is not supported; Home Assistant is not guaranteed.
Key illumination and its behavior in Aqara H1
In no-neutral versions, the indicator is hardware-limited and cannot be configured (it lights only in one position). In versions with neutral, the indicator can be configured, including the “lit when light is off” mode.
Button type and available press actions in Aqara H1
The keys are mechanical (microswitches with short travel). A single press is available; double and long presses are not supported.
“Logical switch” mode and scenarios
H1 channels can be switched to logical mode in Aqara Home and the key can be used to control other Aqara devices or scenarios (subject to the minimum load required to power the device). The logical mode is not available in the Yandex app.
Two-way switching for Aqara H1 (control from two locations)
The classic wired two-way/crossover scheme is not supported. Implement “two-way” control via the combination: a wired H1 on the lighting line + one or more Aqara H1 wireless switches and automations in Aqara Home (a hub is required).
Compatibility with dimmable lamps, LED strips, and drivers
The H1 is a relay switch (phase on/off), not a dimmer. The no-neutral model is not compatible with dimmable lamps, LED strips, and loads whose power may fall below the minimum permissible value. Versions with neutral also do not adjust brightness but can power an external “non-smart” dimmer.
Load type limitations and recommendations
The 8 A limit applies to resistive loads (lighting); for non-resistive loads (drivers, electronic ballasts, etc.) the permissible power is lower (as a guideline — up to ~200 W). For pumps, fans, and other loads, the no-neutral version may lack sufficient minimum power — use the version with neutral.
State memory and recovery after power loss
In Aqara Home, “state memory” is configurable — channel behavior upon power restoration (turn on/turn off/restore last state). Automatic reconnection to the hub after power recovery is supported.
.Zigbee mesh: signal relaying
No-neutral H1 switches do not operate as Zigbee routers. Versions with neutral are mains-powered and can relay the signal, improving coverage.
Protection and operation of Aqara H1
Built-in thermal protection prevents overheating. Operating conditions: 0…+40 °C, 5…95% RH (non-condensing). Observe the MAX mark on charts/diagrams and do not exceed the rated values.
Working with voice assistants
Through the Aqara ecosystem, Apple HomeKit (via an Aqara hub), Google Assistant, as well as Yandex and Salut (Sber) are available. For Yandex, both direct (via a Zigbee Station/hub) and cloud integration (via an Aqara hub) are possible; without a Zigbee module in the speaker, direct integration is impossible.
Can I connect Aqara H1 to an older two-wire network?
Yes, the no-neutral version (WS-EUK01/02) is designed for two-wire networks where only the live conductor is present in the wall box. It is important to observe polarity during connection, ensuring a reliable contact and a minimum load of at least 9 W for LED lamps.
