Using Zooz ZEN16-800LR as dry contact input for garage door reed switch (position sensing only)

Configuration Z-Wave
1

I’m using a Zooz ZEN16-800LR in Home Assistant (Z-Wave JS) to trigger two garage doors via R1 and R2. Relay control works perfectly.

Now I’d like to use the ZEN16 switch inputs (SW1 and SW2) with wired magnetic reed switches to detect door open/closed state.

Goal:

  • Reed switch reports position only
  • Does NOT directly control the relay
  • Shows up as a binary_sensor in HA
  • Used for cover state

Hardware:

  • ZEN16-800LR (800 series)
  • Simple 2-wire dry contact reed switches
  • Home Assistant 2026.x with Z-Wave JS

Questions:

  1. What is the correct wiring for a dry contact reed on the ZEN16-800LR?
    SW1 → ? and ?
  2. Which configuration parameters must be changed so SW1/SW2 report state without toggling the relay?
  3. Should Parameter 31 (Input Behavior) be set to “report only” mode?
    If so, which exact setting?
  4. What should “Switch 1 Type” be set to for a simple reed switch? Toggle? Momentary?

Right now:

  • Relay triggering works
  • Input entity exists and is enabled
  • Moving the magnet does not change state

Looking for confirmation of correct wiring + parameters for dry contact sensing only.

Thanks.

I would ask Zooz about this, they have great tech support.
