Aqara H1M Smart Wall Switch (1-Key)

The Aqara H1M Smart Wall Switch is a wired in-wall switch for smart lighting control. This single-key version is the neutral-line model ZNQBKG24LM. Unlike the visually similar H1M wireless controller, it connects to the electrical circuit and can directly switch one physical lighting circuit, while also making those controls available to an Aqara smart-home system.

H1M communicates over Zigbee 3.0 and is designed to work through a compatible Aqara hub. Once added to the Aqara system, the connected lighting can be included in scenes, schedules and automations while the front keys remain available for normal local operation. Aqara's support documentation specifically separates this wired role from the wireless H1M: the wireless model only sends control commands, whereas the wall switch physically controls power to its connected load.

Aqara lists the H1M neutral-series body at 86 × 85.5 × 43.6 mm, excluding the mounting bracket, with a rated input of up to 220 V AC at 50 Hz. The total rated load is up to 2200 W, with an operating temperature range of 0°C to 40°C and 0–95% RH non-condensing humidity. The product is intended for the China-market H1M installation format, so wall-box dimensions, wiring practice and local electrical requirements should be checked before installation. Mains wiring should be handled with the circuit isolated and, where required, by a qualified electrician.

The single-key version is useful when the H1M design and Aqara automation features are wanted together with direct control of one physical lighting circuit. It is an Aqara-ecosystem switch rather than a generic Wi-Fi switch, so the hub and app environment are an important part of the installation plan.
