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:

The ZEN55 works great! It integrates well with home assistant, and can differentiate between the smoke and CO sounding of the alarms. It's the perfect cost saving solution for not having to replace all of your hardwired smoke and CO alarms with more expensive smart alarms.
Took maybe 5 min total to install and immediately showed up on home assistant with smoke and co monitoring entities. I couldn’t find a decent zwave detector and this allowed me to use what I already had or buy a good “dumb” detector. Highly recommend
Although first one was DOA, support sent me a new one. Took about a week but I am happy.
Wired up quickly and tested with combo smoke and CO detectors. Works flawlessly
No complaints, everything worked immediately
