How to install a Smart Mini Relay

This knowledge article provides a step-by-step guide on installing a smart mini relay and explores its various popular use cases and applications.

Preparation

The Smart Mini Relay is an incredibly versatile device that offers the convenience of remotely controlling circuits or switching between two circuits. With its three latching positions, it is perfect for operating devices that require both an on/off or open/close function and a stop or pause function, such as blinds, curtains, and doors.

This relay is capable of switching loads up to 500W, whether they are mains powered or volts free (low voltage). In fact, the relay itself can even supply power to the circuit if needed (please refer to the wiring instructions for more details).

To ensure safety and compliance with IEC Class II requirements, it is important to house the Smart Mini Relay in a suitable enclosure.

The Lightwave LW824 Waterproof housing is an excellent choice, as it not only minimise the risk of contact with live electrical wires but also allows for outdoor installation.

Tip: One common scenario where the relay is frequently used is when dealing with non-dimmable lighting circuits or circuits that surpass the maximum wattage of a dimmer.

Installing the Relay

1.1 Before installation, it is essential to find a suitable location to house the Smart Relay. This will minimize the risk of coming into contact with live electrical wires and ensure compliance with IEC Class II requirements. If you are unsure, we recommend consulting with a qualified electrician.

1.2 Prior to installation, it is important to turn off the mains power supply to your existing power circuit at the consumer unit.

1.3 The Smart Mini Relay requires mains power to operate, even if it is used for volts free switching. Connect the line and neutral power cables to the Relay following the diagrams provided. Please note that existing cables may vary in color and may not always be correctly labeled. If you have any doubts, it is always best to consult with a qualified electrician.

To connect the circuit, the Smart Mini Relay can be used for mains powered switching up to 500W or separate volts free switching for circuits that do not require additional mains power. The Relay has three latching positions: 0 (no circuit connected), 1 (Circuit 1 connected), and 2 (Circuit 2 connected - optional). Follow the instructions below to wire the relay for the desired configurations.

Some blinds, shutters, and opening devices may require a pulse mode to operate effectively. Our Smart Mini Relay includes this feature, which can be accessed through the relay settings in our app.

This mode is particularly useful when working with various types of controllers commonly used for blinds, garage doors, gates, and similar applications. Different controllers might necessitate a brief pulse to fully open or close the device, making the pulse mode essential for proper functionality.

In this mode the relay closes the contacts to provide a pulse that matches the length of the time you have set in the app (0.5-6 seconds), this is basically to simulate a button press and release action

The relay's internal contacts will disengage after pressing Open or Close, but the app will still show the sate you had selected after sending a pulse to the controller/connected device

The implementation of pulse mode can vary depending on the controller manufacturer, so it is important to carefully review the details of the controller before connecting it to our relay.
