As much as we love Aeon Labs micro switches, they can be a pain to install. Here are the 3 key ingredients for a quick and easy set-up of the switches:
Like with any Z-Wave switch, you will need a neutral connection in each gang box to properly install the micros. Speaking of wiring, if you are looking to install the on/off micro switches in a 3-way setting, use the diagram below (anything else you find in the manuals or online will bring you nothing but trouble).
You will need both line and load in the master gang box for the 3-way installation to be successful.
Last but not least, here are a few useful programming adjustments to get the most functionality out of your Aeon Labs micro switches:
- Parameter 120 = 1 set as default for on/off toggle mode OR 0 for momentary switch
- Parameter 3 = 1 for overload protection
- Parameter 80 = 1 to report status change - controller immediately shows status change if you turn the switch on or off manually
Did I miss anything? Let me know in the comments below!

What is the overload protection! Can it be reset? How?

Hi Brent, good question! Just like with any Z-Wave switch, it can be associated with other devices in your network and can be controlled with a virtual add-on switch like the LTM-5 or a Z-Wave scene controller. So you can hide the relays behind a dry wall and decide where and how you want to add local control for them with Z-Wave scene controllers.

Do you have to connect these to a traditional switch or can you have them controlled by scene controllers / other zwave devices?

Hi David, even though Aeotec publishes the live diagrams as an option, we don’t recommend implementing them because in the long run it may damage the switches anyway. If you’re having issues with reliable control, we would try disconnecting the module from the 3-way and see if you can control it from SmartThings as a single-pole to see if the wiring plays a part here.

This was really helpful, I have wired mine up slightly differently (using a 3 way live implementation but it all works except for the fact that i cant seem to reliably turn it off from smartthings. thoughts on what might be the cause?

Hi Ann! The Vision dual relay can be connected in a 3-way without live wiring just as shown in the Aeotec diagram. So the most important thing to check for is that you have neutral, ground, line, load, and traveler all in one box. We have a dedicated wiring diagram for the Vision module so feel free to email us about it!

I have a quick question: can I hook up one of your dual relay to control a 3-way switch?

Hi Todd,
Thanks for the question! Dimmers will not work in a 3-way configuration because they are based on the push-button mechanism. So even if you replaced regular switches with momentary, you would still not be able to use a dimmer in this configuration.
We recommend replacing your traditional switches with Z-Wave in-wall dimmers to execute a 3-way configuration. We write more about the process here:

Let me know if that was helpful!

Does the 3/4-way wiring differ for the dimmer modules? Specifically, would I connect load and line to the dimmer module and then use momentary switches in place of the toggle switches in the diagram above? Have you or anyone else got that working? Thanks in advance!

You've probably heard the term Z-Wave thrown around if you've been shopping for smart home devices, especially anything related to security systems, door locks, or home automation hubs. But what actually is Z-Wave, and why do so many serious smart home setups rely on it? Here's everything you need to know to get started!
The most important thing to understand about Z-Wave is that it's completely separate from your home's Wi-Fi. Z-Wave devices communicate on their own low-power radio frequency, which means your smart home traffic isn't competing with your streaming, video calls, or anything else on your internet network.

If you’ve ever tried shopping for smart switches, you already know how quickly things can spiral. What starts as “I just want a smart dimmer for my kitchen” somehow turns into reading about 3-way wiring, traveler wires, load ratings, relay switches, neutral wires, smart bulb mode, and whether your exhaust fan will explode if you accidentally install the wrong dimmer.
And honestly, we get it. Once you open up a switch box and start Googling terms like “single pole vs multi-way” or “line and load,” things can feel overwhelming fast. Instead of forcing you to compare every switch model and decipher electrical terminology on your own, our new guide walks you through the decision process step by step so you can narrow down the right switch for your setup without second guessing yourself.

If you love a good DIY project and a touch of smart home magic, you’ll be blown away by what YouTuber DIY With Vinny pulled off. His YouTube tutorial transforms a simple closet into a fully automated, jaw-droppingly smart space, from leak detection to mood lighting and robot-friendly automation.
The best part? It’s powered by some seriously smart Zooz Z-Wave gear that makes everything run seamlessly behind the scenes. All of the Zooz devices featured here support the new Z-Wave Long Range protocol, so your smart home stays connected and responsive, even across floors, garages, or detached spaces.
Let’s take a tour of this build and peek at how you can recreate it in your own home.

Old post I know, but, can you tell me what the difference is between the DSC27103 and DSC19103?
