Here is a list of updates we made to the ZEN77 700 Series S2 Dimmer so far:

VER. 1.0 (released 12/2020)

Original release

Firmware: 1.02

• Central scene triggers for up to 10 scenes or devices

• Smart bulb mode (disable relay)

• Programmable double and single click behavior

• Night light mode (press and hold the lower paddle when the dimmer is off to turn on to low brightness)

VER. 1.03 (released 01/2021)

Firmware: 1.03

• Adjusted association commands to be sent whenever the paddles are pressed, regardless of the current status of the dimmer 

VER. 10.0 (released 05/2021)

Firmware: 10.0

• Removed the delay for on/off control from paddle with scene control disabled
• Added the ability to disable programming function from the paddles (Parameter 26: 0 - enabled; 1 - disabled: you won't be able to include, exclude, or change LED indicator mode from the paddle)
• Fixed relay behavior after power outage in smart bulb mode (both relay and on/off status are restored correctly after an outage now)
• Fixed night light mode (doesn't activate the light anymore when disabled)
• Fixed single-tap behavior bug in a 3-way installation (the connected 3-way switch now honors the single-tap setting as well)

VER. 10.10 (released 10/2021)

Firmware: 10.10

• Fixed the SetLevel command class to accept the duration and other values sent from the hub for level changes (advanced dimmer programming)
• Ramp rate is now calculated with the account of minimum and maximum brightness levels (and just 0 -100 only as before)

VER. 10.20 (released 7/2022 as OTA)

Firmware: 10.20

• Fixed night light behavior (the dimmer no longer sends central scene events repeatedly when night light mode is disabled and the bottom paddle is held).
• Fixed multilevel association to work for both manual and Z-Wave commands.
• Fixed bug: the duration set for SWITCH_MULTILEVEL_SET and START_LEVEL_CHANGE commands is no longer ignored by the dimmer.
• Adjusted dimming scale mapping to minimum and maximum brightness levels.
• Added parameter 30 to adjust dimming multilevel duration for devices associated with the dimmer in Group 3 and Group 4 (see setting details here).
• The value for the single tap setting now applies to Z-Wave control as well (previously it only applied to physical paddle tap).
• Separated ramp rate settings into 4 new parameters: ramp rate ON physical (9), ramp rate OFF physical (27), ramp rate ON Z-Wave (28), and ramp rate OFF Z-Wave (29). See all settings here.

VER. 10.30 (released 10/2022 as OTA)

Firmware: 10.30

• Adjusted Direct Association behavior for Group 3 for full sync and smooth dimming when two or more Z-Wave dimmers are associated together in a virtual 3-way or 4-way set-up
• The value for the double tap setting now applies to devices associated with the Z-Wave dimmer in Groups 2-4
• The Night Light Mode setting now applies to devices associated with the Z-Wave dimmer in Groups 2-4
• Added parameter 7 to choose Direct Association reports sent to devices associated with the Z-Wave dimmer in Group 3. See all settings here.

VER. 10.40 (released 05/2023 as OTA)

Firmware: 10.40

• Fixed central scene bug for control of its own load in smart bulb mode
• Added parameter 32 to disable LED blinking when a setting is changed. See all settings here.
• Changed the manual operation for disabling the relay (smart bulb mode): Hold the UPPER paddle for 10 seconds until the LED indicator starts blinking, then within 2 seconds, tap the upper paddle 5 times quickly to change this mode. The LED indicator will stay solid green for 3 seconds to confirm the change.
• Improved the factory reset procedure: The switch will not lock up if the factory reset is not successful in certain scenarios. 

VER. 2.0 (released 07/2022)

Hardware: 2.0
