1

Firmware: 3.60 (released 06/2025 as OTA)

  • Added new parameters: 35 – Scene Control Multi-Tap, 36 – LED Indicator Multi-Color, and 37 – Gamma Factor. You can view all available settings here.

Firmware: 3.70 (released 07/2025 as OTA)

  • Optimized Z-Wave reporting behavior: when Basic Set, Binary Set, and Multilevel set commands are sent from the Z-Wave controller (Lifeline), the device will no longer send redundant report or notification commands back to the controller.

We don’t recommend updating your device unless you’re missing any of the functionality listed in the changelog, and the update is absolutely necessary. Before you attempt an update on your device, please read this first:

  • Remember to unzip the file after downloading it before using it to update your device. 500 series device files will use the .otz or .hex format while 700/800 series device files will use the .gbl format.

  • Always double-check that you’re applying the correct firmware file to the right model and version of your Zooz device. Loading the wrong version to your device may deem it unusable.

  • You may need to exclude and re-include the device after the update is complete for best performance. Please consider that you may need to rebuild all of your automations and settings for the device.

This just caught my eye! Doing a little quick searching it seems the ZEN71 has this feature also. What other switches have this feature? That is a really useful improvement, IMHO. Hoping it comes to the ZEN77, 76 and 75 as well.

It would also be incredibly cool if when you have an auto-off setting configured, that the last 30 seconds of time left on the timer could cause the led to flash. But now I’m just dreaming!

@getoffmylawn A new firmware update for the ZEN71 will be released today, introducing support for an additional LED indicator parameter. This update will also be rolled out to all our switches and dimmers.

Currently, our devices offer an LED indicator parameter that lets you choose how the LED behaves. The new parameter adds the ability to configure a different LED color based on the switch state — specifically, to show a different color when the load is ON versus when it is OFF.

Example:
On the ZEN72, the LED is blue when the load is OFF. With the new parameter, you can now configure the LED to turn green when the load is ON, while keeping it blue when the load is OFF.

LED Indicator Multi-Color

Parameter 36: Choose the color of the LED indicator in opposite switch state (instead of off) when the LED indicator mode (parameter 2) is set to values 0 or 1. The color chosen in this setting will apply instead of the default “off” value (LED doesn’t light up).

Values: 0 – off; 1 – white; 2 – blue; 3 – green; 4 – red. Default: 0.
