Frequently Asked Questions

What does the SM308-2CH Zigbee Switch Module do?

The SM308-2CH is a dual-channel Zigbee 3.0 on/off switch module that controls two independent lighting circuits from a single in-wall module. Each channel can be controlled separately through any Zigbee 3.0 platform (Philips Hue, Home Assistant, SmartThings, Hubitat, etc.).

Does the SM308-2CH require a neutral wire?

Yes. The SM308-2CH dual-channel module requires a Live + Neutral wire — neutral is required for this product. If your wiring does not have a neutral at the switch position, consider the single-channel SM308-S instead, which works without a neutral.

What load can each channel of the SM308-2CH handle?

Each channel supports up to 2A LED, 2A incandescent, or 4A halogen load.

Which smart home platforms does the SM308-2CH work with?

The SM308-2CH integrates with Philips Hue, HomeKit, Amazon Echo Plus, Hubitat, and Home Assistant (via ZHA, deConz, Conbee, Raspbee), plus other Zigbee 3.0 gateways.

Can each channel be controlled independently?

Yes. The SM308-2CH features two independent channel outputs that can be controlled separately by two switches (using a universal single-wire push switch), or independently from your smart home app.

Does the SM308-2CH support energy monitoring?

Yes. The SM308-2CH includes active power and energy metering, exposed via the Zigbee Electrical Measurement (0x0b04) and Simple Metering (0x0702) clusters.

How many green power switches does the SM308-2CH support?

As a Zigbee router device, the SM308-2CH supports up to 20 green power switches via find-and-bind mode and Touchlink commissioning.

Where does the SM308-2CH install?

The SM308-2CH is a compact in-wall Zigbee module measuring 42 × 38 × 16 mm. It fits behind your existing light switch in a standard UK back box.

  1. Requires a neutral connection.
    Be aware, unlike the other SM308 products, this one requires a neutral wire. It does state this in the description, but it’s not that obvious.

  3. Great product, just as good as the other SM308 models, though the range would benefit from a no-neutral two-channel version.
