NOTE: If you don't see your Z-Wave controller on the list above, please ask the manufacturer of your Z-Wave hub about support for the ZEN55 before you purchase this product.
Check your wiring first to confirm that you have all the following wires present in your electrical box: power, neutral, and the connection to the detector.
If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.
Here is an example diagram showing how to wire the ZEN55 to a smoke detector:

I just installed the ZN55 today, so the verdict is out on how well it will perform over the long-term, but installation was straight forward and triggered as expected when my interconnected smoke alarms were manually tested. The only issue was that it took a little cajoling to add the device to my Home Assistant instance, but once paired it worked fine. The product materials seem well made, and the size was small enough to pack into the smoke detector junction box with the existing wiring.
Easy to set up and it works.
This device was very convenient to pair and easy to install. No problem to fit it in the smoke detector box. Very good instructions included in the package. It is reporting smoke and CO within seconds when the hard wired detector cycles through test mode.
Insanely simple install. This was the first z-wave device I installed and setup with the usb 800 dongle was extremely easy in home assistant.
I was looking for a way to integrate or smoke and CO detectors into Home Assistant. This relay did the trick and was easy to install.
