Original release.
Hardware:

  • 700 Series Z-Wave chip
  • Single pole or direct 3-way capability

Firmware: 1.10

  • 3 switch types to choose from (on/off toggle fixed to position, on/off toggle regular, momentary + impulse 3-way wiring mode for selected 3-way scenarios)

  • Smart bulb mode

  • Scene control (works best with momentary wall switches)

VER. 1.30 (released 6/2022)

Hardware:

  • Fixed the wiring limitations for wall switches not triggering the relay in selected scenarios

Firmware: 1.30

  • Optimized performance in different wiring scenarios

VER. 1.40 (released 8/2022 as OTA)

Firmware: 1.40

  • Fixed reverse behavior for toggle switch with fixed action (always toggle up for on, always toggle down for off)
