Switching actuator Homematic IP 156757A0 — 230 V AC, 1380 W, 868.6 MHz

The Homematic IP switching actuator 156757A0 is a compact dual-channel module designed for integration into smart home electrical installations. It operates on 230 V AC and communicates via the 868.6 MHz Homematic IP wireless protocol. Housed in a small enclosure (71×37×71 mm), the device is suitable for installation in standard flush-mounted boxes or behind existing wall switches to enable remote or local switching of connected lighting and loads with a maximum combined switching capacity of 1380 W and an indoor wireless range up to 150 m.

Advantages

The dual-channel design allows control of two separate circuits from a single actuator, reducing installation complexity and saving space. Screwless terminals simplify wiring and increase installation safety. The device supports multiple control options: manual switching on existing wall switches, smartphone app control, voice assistants and Homematic IP remotes. Compact form factor enables discreet installation out of sight while maintaining full functionality for timed events and automation scenarios.

Suitable for

• Controlling two ceiling lights or lighting circuits from one installation point
• Retrofit installations behind existing switches in residential interiors
• Integration into timed routines and event-based automations (e.g., sunrise/sunset)
• Voice-controlled light switching via compatible voice assistants

Key specifications

• Supply voltage: 230 V AC
• Maximum switching capacity: 1380 W (combined)
• Wireless frequency: 868.6 MHz (Homematic IP protocol)
• Indoor wireless range: up to 150 m (typical, depending on environment)
• Dimensions: 71 × 37 × 71 mm (suitable for flush-mounted box installation)
• Number of switching channels: 2
• Connection type: screwless terminals for live and switched conductors

How to use

Install the actuator in a standard flush-mounted box or behind an existing switch following electrical safety rules and local regulations. Connect the supply and load conductors to the screwless terminals, ensuring the combined load does not exceed the specified maximum switching capacity. Pair the actuator with a Homematic IP access point or gateway via the 868.6 MHz wireless link and configure channels in the app. After commissioning, operate the outputs manually from wall switches, via the Homematic IP app, by voice commands through supported assistants, or using compatible remotes and pushbuttons.

Recommendations

To ensure reliable operation, distribute loads across the two channels to avoid exceeding the combined switching rating, check cable cross-sections and connections during installation, and position the actuator within adequate range of the Homematic IP access point. For safety and compliance, installation should be performed by a qualified electrician.
