NOTE: If you don't see your Z-Wave controller on the list above, please contact us before you purchase this product.
Before installing, make sure the load does not exceed the Wattage provided in the specs. Check your wiring first to confirm that you have all the following wires present in your gang box: load (most often black), line (most often black), neutral (most often white), and ground (most often green).
If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.

SmartStart Inclusion:
Open your hub's app and initiate pairing as usual. Scan the SmartStart QR code on the ZEN57 relay and power it up - it will include automatically. You don't need to click the Z-Wave button unless you're using SmartThings in which case, you may need to activate the relay by tapping the Z-Wave button 3 times quickly.
Manual Inclusion:
These devices are just amazing. They work great to retrofit lighting using existing switches, as well as 1,001 other uses. Please note, there is a very slight delay (like a quarter second) when turning on a light using the existing switch. Easy to adapt to, but it is there. Also, if the existing switch is in the "ON" position, and then the light is switched "OFF" via Z-Wave, then the light will be "OFF", even though the local switch is in the "ON" position. To turn the light back on via the local switch, you have to flip the switch to the "OFF" position, then back to "ON".
Worked great, and is tiny. Fit inside my china case no problem.
Installation was a breeze and functionally these things are great, but if you try to manually include it will fail/hang halfway. SmartStart is the only way I was finally able to get these to include.
Had these smart relays existed a couple of years ago when I started my smart home journey, 40 of the 60+ such devices in my home would have been of this brand and type. They're so small and focused on saving space in the box. The built-in leads for connecting a switch and the two-port neutral bus are just brilliant ideas for saving space and lower setup time. Be careful not to connect these to inductive loads like motors. They're strictly for resistive loads like lighting operating at or below five amps. As it turns out, the vast majority of my home automation use cases are just low amperage lighting. These devices are perfect for that.
Have not used long, but working fine
