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!

Smart home tech isn’t just for indoors anymore—it’s transforming yard care too. While we’re used to voice assistants and smart thermostats, outdoor tools like sprinkler systems are catching up. Instead of wasting water on rigid schedules, smart systems adapt to the weather, skip rainy days, and keep your lawn healthy with minimal effort.
Smart sprinkler control makes it easy to upgrade your existing irrigation system with a device like the Zooz ZEN17 Universal Relay. Compatible with SmartThings, Hubitat, Z-Box, Home Assistant, and HomeSeer, it fits into most smart home setups without locking you into one platform. This post covers the benefits of automating your sprinklers, how to set up the ZEN17, control options, and real user tips to help you get the most from your system.

Imagine this: it’s a stuffy summer night, and you’re already in bed when you realize the ceiling fan is off. Or maybe you’ve left the house and can’t remember if the bathroom fan is still running. What if your fan could turn on automatically when the room gets too warm—or shut off when no one’s around?
That’s the beauty of smart fan control. It’s not just about convenience (though turning your fan on with your voice or a tap on a smart remote is pretty great). It’s about making your home more energy-efficient, more responsive, and just... smarter.

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