How Does EVVR In-Wall Relay Switch Lite Work?

There's little difference in the working of an EVVR in-wall relay switch and an EVVR in-wall relay switch lite. Both work on the same principle, which is the electromagnetic mechanism. Need to know what it is? The Evvr in-wall relay switch lite has a magnet inside that turns it on and off. When current flows through the switch, the magnet attracts the iron armature, pushing the other end together.

This results in complete circuit formation and current flows throughout the circuit, which turns your EVVR in-wall relay switch lite on.

Another noticeable thing is that even if your ZigBee light switch is off, the current will flow through it, and you can control the switch through the ZigBee hub. What more? You don't need extra wires to install this switch and make it work. Therefore, this EVVR ZigBee light switch gained huge popularity among people having homes built in the 80s or 90s.

After the internal working of a ZigBee light switch, let's discuss the operational working of the Evvr in-wall relay switch lite.

Operational Working

Here's the step-by-step procedure:

  • First, open any ZigBee-compatible app on your phone and scan the QR code on the switch to add the device to the app. You can also add the device type and name it manually in the app.
  • Next, turn on the ZigBee hub by pressing the reset button and make sure its load light is on. Wait for at least 30 seconds until the pairing indicator on the ZigBee light switch starts to blink blue.
  • The hub will automatically detect the device next time and connect to it within no time.

How to Ensure Your EVVR In-Wall Relay Switch Lite is Working Smoothly?

Like the EVVR in-wall relay switch, the EVVR in-wall relay ZigBee switch lite must also be installed near the hub to ensure no signals drop out. Don't know how to check if the ZigBee hub is connected to the switch? If the LED indicator on the controller is showing a blue color, it means the connectivity is smooth. However, if the indicator has a red light, it shows the hub isn't connected to the switch; thus, the relay controller will not work.

How to Switch Between Different Switching Modes in the Evvr In-Wall Relay Switch Lite?

The process of going towards different switching modes in the ZigBee light switch resembles the EVVR Homekit in-wall relay switch. You can get a better idea about it from the table given below:

How to Wire EVVR In-Wall Relay Switch Lite?

Compared to a simple EVVR in-wall relay switch, this relay switch lite is easier to install due to its smallest switch size. It's a two-part device: a smart switch panel and a smart relay lite. The smart switch panel is an optional accessory, but it's good to install it if you want to give your ZigBee light switch network commands even when it's off. Let's look at a step-by-step guide on how to wire or install a ZigBee light controller.

Step 1

The first step is to turn off the circuit breaker for the switch so no current flows while you are wiring the new EVVR in-wall relay switch lite. Doing so saves you from electrical leakages and potential risks of getting electrocuted.

Step 2

Now it's time to install the smart switch panel in your ½ gang switch. For this purpose, take out the cover of the nearby fixture. Detach two wires from that fixture, connect the live wire to the L connector, and load the wire to the L1 connector. Slip in the panel in your switch and go towards the next step.

Step 3

The next step is installing the smart ZigBee light relay switch. Remove the cover of the same fixture near your bulb or lamp, and remove the wires connecting the switch to the bulb. After that, connect the neutral wire to the N terminal, and the output Live wire to the L Out 1 connector.

Step 4

Push all the wires and the relay lite back into the fixture and cover it up with the plastic case you previously removed. Lastly, turn the power back on and wait for a few seconds until the switch starts working.

Applications of the EVVR In-Wall Relay Switch Lite

The applications of the EVVR smart relay switch are the same as that of the EVVR simple relay switch. Other than opening ways for lighting automation, you can utilize this smallest switch to control other home devices or appliances. The most common are smart security systems, smart doorbells, innovative kitchen appliances, etc.

Compatibility of EVVR In-Wall Relay Switch Lite with Other Hubs

The EVVR in-wall relay switch lite is an excellent product for people who don't have a ZigBee hub and want the device to connect to any other available hub. EVVR In-Wall Relay Switch Lite is compatible with standard Zigbee 3.0 smart home hubs, SmartThings, Amazon Echo, Aeotec, SONOFF, eWelink, and other third-party hubs.

The most suitable alternative is Z-Wave as it has a better range and the signal doesn't drop even if you live in a huge villa. Moreover, Z-Wave runs on a different spectrum, so your home's WiFi connection won't affect its connectivity with your switch. As Z-Wave has more companies signed up, you can explore more options and get the maximum out of your light switch.

Difference Between In-Wall Relay Switch Lite and In-Wall Relay Switch

As mentioned earlier, there's not much difference between In-Wall Relay Switch Lite and In-Wall Relay Switch. A few noticeable differences are in compatibility, the In-Wall Relay Switch Lite works with ZigBee 3.0, SONOFF, Amazon Echo, SmartThings, etc.

Compared to In-Wall Relay Switch, the In-Wall Relay Switch Lite shares the same features that it supports all kinds of light bulbs with no workload limitation. At the same time, In-Wall Relay Switch Lite is a more economical solution with which a single/dual/three-gang rebound switch included.

However, the installation process doesn't vary much, and you will follow the same steps you performed during the wiring of the EVVR in-wall relay switch. With In-Wall Relay Switch Lite, you need to connect it to a ZigBee or any third-party hub while the In-Wall Relay Switch efficiently connects with Homekit.
