Shelly WAVE i4 DC wireless input switch/scene controller

The Shelly Qubino Wave i4 DC Smart Module is a member of the Shelly Wave family, which uses the Z-Wave protocol (868.42 MHz in Europe) for communication. As Z-Wave is the protocol for smart homes, it was developed specifically for communication between smart devices. The sub-gigahertz frequency allows good signal propagation and the Z-Wave MESH network topology allows devices that are remote from the central unit to communicate properly (devices under constant power act as a signal transmitter). Z-Wave devices require a Z-Wave Hub or a USB coordinator (e.g. connected to a miniPC) to operate. The Z-Wave protocol uses a single communication command class, so thousands of products from hundreds of different brands are compatible with each other, and devices in a Z-Wave system can work together as a network. A Z-Wave network can contain up to 232 devices. An additional benefit of the Z-Wave protocol is that it supports group associations, which allow direct associations to be created between individual devices on the network. An additional advantage of Z-Wave devices is that they can be configured with a number of parameters at protocol level so that they can be tailored to the most specific needs.

The new Shelly Qubino Wave i4 DC is a special product from the manufacturer, a version of the Shelly Qubino Wave i4 DC. The i4 DC has no built-in relay, but can detect the status of up to 4 switches or other DC devices and control other Shelly Wave relays or trigger a scene using the door.
The Wave i4 DC is a version specifically designed for DC switches and is also suitable for monitoring the status of door motors, alarms, doorbells and other DC devices.

It is also available to wirelessly "connect" a DC switch (e.g. in a caravan or motorhome) to a control device connected to a Shelly Wave relay installed elsewhere. A module installed behind the Shelly Wave i4 DC switch(es) detects changes in the state of the switches and can send a switching command via the Z-Wave protocol to Shelly Wave 1, Shelly Wave 1PM or Shelly Wave 2PM relays or other relays, and can also control multiple relays in a group with a single switch. The Shelly Smart Relay can therefore be used in pairs, even if the switch and the monitored consumer are far apart or if there is simply no wiring between them.
It can receive signals from up to 4 connected physical switches and connect up to 3 events to each of them. You can also assign different commands to these 3 switching modes in the Scene function. Shelly's Wave i4 DC can therefore also be used to control scenes from a wall-mounted physical switch.
Like other Wave devices, the Wave i4 requires a Z-Wave hub or gateway to operate, and cannot connect directly to a WiFi router.

Mating:

The module has an "S" button, which is a function button. This button is used to initiate pairing, unpairing and factory reset procedures. These functions are available for a limited time after switch-on.

Pair/unpair/factory reset:

Press and hold the "S" button to steam until the status indicator turns blue. Then press the "S" button again directly (min. 2 seconds) to initiate the mating/disconnecting state.

Z-Wave nodes:

Shelly has been tested with the following Z-Wave nodes:

• Home Assistant
<li style="text-align:
• Home Centre 3
• Jeedom
• Homey
• SmartThings
• Hubitat.

Shelly Wave i4 DC requires a constant 5V-24V DC power supply to operate.

It expects the same voltage at its four switch inputs and

• detects whether the switch is on/off,
• or, if not used for a switch, to detect if there is current in the circuit.

Product features:

• Compatible with 5V-24V DC supply voltage, DC supply voltage and supply voltage from switches/circuits must be the same
<li style="text-align:
• Also supports button combinations (3 functions per button) for a total of 12 options per module (1x, 2x, hold down)
• Indirect control of other Z-Wave devices via association functions 8 options per module (1x, hold-down)
• Ideal complement to the Shelly Wall Switch (1-2-4 button versions)
• It can also be used to detect the input conditions of other low-current devices

Specifications:

• Input: the actuator expects a DC voltage level at the input terminals "i"
• Input voltage: 5-24 V DC
• Low standby power consumption: 0.3 W
• Communication protocol Z-Wave 800
• Z-Wave frequency: 868.4 MHz (EU)
• Distance: up to 40 metres inside the building (walls can be reduced with panels)
• SmartStart: encryption S2: YES: YES
• Z-Wave repeater function: YES
• Z-Wave repeater function: YES YES
• Wireless firmware update (OTA): YES
• Operating temperature: -20 - +40 °C
<li style="text-align: Size: 37 x 42 x 16 mm
• Weight: 37 g

Shooting options:

<li style="text-align: DIN rail adapter (separate product) can be used to mount the module on the C-rail, can be aligned

DIN rail header (separate product) for mounting on C-rail, can be aligned

Shelly Wave i4 requires a constant DC power supply of 5-24 V.

It expects such voltage at its four switch inputs and:

• detects whether the switch is on or off,
• or, if not used for a switch, to detect if there is current in the circuit.

Wave i4 is compatible with the new Shelly family of light switches with a four-button "scene control" switch that can be easily clicked on the back to create commands to control other devices (group or scene) in the Shelly system.

(The 4-button wall switch is not included with the Shelly Wave i4 DC, but is available as a separate product).

Like other smart relays, it requires a neutral conductor in addition to the phase conductors to operate.
