ZEN16 VS ZEN17: What's the Difference
There is a lot of smart home potential with the Zooz relay devices - so which model should you go with?
Here are the main differences between the ZEN16 MultiRelay and the ZEN17 Universal Relay:
- The ZEN16 has 3 NO relay while the ZEN17 has 2 NO-C-NC relays.
- The switch inputs on the first version of the ZEN16 were fixed to the relay outputs and you couldn't monitor them separately of the relays while the inputs on the ZEN17 can be separated from the relays and monitor analog binary sensors for open/close, dry/wet, etc. With the new ZEN16 VER. 2.0 you can now separate inputs from outputs and customize how the inputs display in your hub to monitor analog sensors and other dry contact inputs.
- The switch inputs on ZEN16 are dry contact only which means you can't connect any voltage to them while there are 2 types of inputs on the ZEN17: dry contact (S-C) and low voltage 12-24 V (VC-C) to use low voltage triggers.
- The previous version of the ZEN16 used the 500 series Z-Wave chip with S2 Unauthenticated security while the ZEN17 uses the 700 Series Z-Wave Chip with S2 Authenticated security. The new ZEN16 VER. 2.0 comes with the 700 series chip as well.
| ZEN16 | ZEN17 | |
|---|---|---|
| Relays | 3 NO relays | 2 NO-C or NC-C relays |
| Inputs | Dry contact only | Dry contact (S-C) or low voltage 12-24V (VC-C) |
| Outputs | Tied to inputs, can't be separated on VER. 1.0, but you can separate outputs from inputs on VER. 2.0 | Can be separated from inputs for monitoring analog binary sensors independently of output control |
| Garage Doors | Recommended when using wireless sensors to monitor the garage door open/close status | Recommended when using wired reed sensors to monitor the garage door open/close status |
