Älykäs WLAN-kytkin Sonoff MINI-D AC/DC 12–48V jännitteetön kosketin

SONOFF MINI-D Smart WiFi Matter Switch (AC/DC 12-48V, dry contact) is a compact WiFi module with a potential-free (dry) contact designed for control and automation of low-voltage and mains-connected devices. Compatible with the Matter standard, the MINI-D integrates with major smart home platforms such as Google Home, Apple Home and Amazon Alexa and can be used with Home Assistant. The module supports AC 100–240V (0.1A) or DC 12–48V (1A) power supply, has built-in 2.4 GHz Wi‑Fi (IEEE 802.11 b/g/n) and an ESP32-based controller for reliable communication.

Advantages

The SONOFF MINI-D provides flexible control through a potential-free contact that isolates the controlled circuit, preventing voltage transfer to connected devices. Matter compatibility ensures broad ecosystem integration and voice control across popular platforms. Support for both AC and DC power supplies and a compact form factor make the module suitable for varied installations, while built-in scheduling, group control and automation functions allow timed and scenario-based operation.

Suitable for

• Remote control and automation of garage doors and gates
• Integration with heating systems, boilers and thermostats
• Controlling valves, solenoid actuators and irrigation systems
• Driving contactors to switch larger loads such as pumps and HVAC equipment
• Use in professional building and industrial automation requiring a dry contact interface

How to use

Install the MINI-D inside a junction box or enclosure near the controlled device, following local electrical regulations. Connect the module to the appropriate power source (either AC 100–240V or DC 12–48V) and wire the potential-free contact to the device input or to a contactor coil as required. Add the device to your Matter-compatible smart home ecosystem (Google Home, Apple Home, Amazon Alexa) or to Home Assistant using the supported provisioning method. Configure schedules, group control or automation scenes in the chosen app to enable remote control and timed operation.

Recommendations

Use the MINI-D’s dry contact to interface with low-voltage control circuits and contactor coils; when controlling high-power loads, switch them via a suitably rated contactor or relay. Ensure wiring and installation are performed by a qualified technician and comply with local safety standards.
