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:

No complaints, everything worked immediately
Works great!
Installation was simple and works perfectly with hard-wired Smoke Detectors and hubitat! Highly recommended product!
The ZEN55 800LR is easy to install into your existing hard-wired smoke detector setup. After joining it to my Hubitat hub, and setting up a notification routine, I had my existing hardwired smoke detectors sending notifications to my phone (even when pressing the Test button) within minutes. Excellent product for piece of mind.
Sensor is easy to install if you can fit into your box. The Sensor paired with smartthings app and works well. It does not show what went off ie: smoke or c/o or which detector but it immediately informs you something in the system went off and you can follow up. Inexpensive option to know your detector went off when not home.
