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 ZEN16 are fixed to the relay outputs and you can'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.
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 ZEN16 uses the 500 series Z-Wave chip with S2 Unauthenticated security while the ZEN17 uses the 700 Series Z-Wave Chip with S2 Authenticated security
