We may have this product available in open box, refurbished, or used condition - just check the variant buttons under the product price for availability. All of our recycled inventory has been tested for both manual and Z-Wave control and is fully functional at the time of shipment. Here is what you can expect when ordering your device:
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:
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.

Connected this to my hardwired smoke detector and paired to home assistant. Small size made it easy to fit in existing box. I did have to supply 2 small wire nuts to cap off the unused relay outputs.
I received my replacement quickly, however the replacement is the same firmware version that it was replacing, we will see if it fixes the issue.
Worked right out of the box, scanned the QR code and wired into the existing smoke detectors. Popped up with smoke and CO stuff i could use to trip automations with. No additional configuration was needed for my First Alert Smoke/CO detectors.
I had one bad smoke detector, so I was originally looking for a smart one to replace it with; one that would integrate with Home Assistant directly. I already had the SkyConnect as a Zigbee hub, so that's the way I was leaning. Then I decided that I may as well add a Z-Wave hub for more flexibility in my home. That's when I came across the Zooz stick and this DC sensor. The item arrived quickly. The packaging was nice. The instructions were easily understood. Can't ask for much more than that. I could ask that it works for real, but I'd rather not find out, if you know what I mean. ;)
After moving into a 12 year old home and getting a Home Assistant server running, I wanted to find a way to integrate the 8 wired and interconnected smoke detectors throughout the house. The smoke detectors were original (12 years old) and needed to be replaced, so I considered purchasing 8 new Z-wave detectors to replace the existing First Alert units. However, I had trouble finding wired Z-wave replacement units that I wanted to put in the house. This would have been an expensive path, but I would have gone this way if I hadn’t ‘stumbled’ onto this amazing product. The ZEN55 LR offered a creative solution for my situation, and installed easily just like any Z-wave product and provided sensors for both smoke and carbon monoxide notifications as reported by the detectors. I found hard-wired replacement First Alert smoke AND carbon monoxide detectors (upgrade to the smoke only detectors already in place) at a local big box store, and installed them, along with the ZEN55 LR. It was easy to build a few automations in HA to provide notifications on events - providing peace of mind when leaving the house for any period of time. Thank you for providing such a creative product.
