Here is a list of the changes and updates we made to the ZEN17 Universal Relay so far.

VER. 1.02 (released 3/2021)

Original release.

  • 2 x NO-C-NC relays and double inputs (dry contact + 12-24 V)
  • USB C cable included (power adapter sold separately)
  • 700 Series Z-Wave Chip

Firmware: 1.02

  • 4 switch types to choose from (on/off toggle fixed to position, on/off toggle regular, momentary, garage door mode)

  • 7 input types to choose from to monitor separately from output control (bug for open/close reports: will report in reverse for most door sensors)

  • Built-in timer available in seconds, minutes, and hours (doesn't work if any of the 7 monitoring inputs is enabled and input control is disabled)

  • SmartStart + S2 Authenticated Security supported

VER. 1.03 (released 6/2021)

Firmware: 1.03

  • Fixed open/close reports for input monitoring (no longer show status in reverse)

VER. 1.04 (released 5/2021 as OTA file only)

Firmware: 1.04

  • Added additional switch type: garage door mode for relay + open/close type for input
  • Fixed endpoints created for inputs and outputs (static with different types of reports)
  • Fixed the timer bug (timers now work even if the input type is set to monitoring sensors)

VER. 1.10 (released 4/2022 as OTA file only)

Firmware: 1.10

  • Parameters 19 and 20 added to reverse the reporting on sensor inputs (see all setting details here)
  • Fixed reporting behavior after power outage: if parameters 2 or 3 are set to 7, and parameters 10 or11 are set to disabled, the status on inputs is now updated when it's changed during a power outage so correct status is showed after the power is restored

VER. 1.20 (released 6/2022 as OTA file only)

Firmware: 1.20

  • Fixed reporting behavior after a power outage: if parameters 2 or 3 are set to any value, and parameters 10 or11 are set to disable, the status on inputs is now updated when it's changed during a power outage so the correct status is shown after the power is restored (version 1.10 only fixed the issue for parameter 2 and value 7, this is now fully addressed)

VER. 1.30 (released 4/2023 as OTA file)

Firmware: 1.30

  • Fixed setting bug: you can now set any value for parameter 2 or 3 (input type) when parameter 24 (DC motor mode) is set to value 1 (enabled).
  • Fixed setting bug: R2 output now behaves correctly after a power outage with input type set to garage door mode (parameter 3 set to value 11). It no longer needs to be turned on and off first to resume normal operation.
  • Added new settings to set input trigger duration (parameters 25 and 26, see all settings here)
  • Added new setting to assign fixed on or off actions to inputs (parameter 27, see all settings here)

VER. 1.40 (released 11/2023 as OTA file)

Firmware: 1.40

  • Fixed a bug with the auto turn-off timer for R1 and R2 whenever parameters 10 and 11 are changed from value 1 to 0. Parameters 2 and 3 values 0-10 were affected.
