How would you sync switch LEDs in a virtual 3-way? Zooz Zen30

[kchurchill]

I just finished setting up 2 Zooz Zen30 switches in a virtual 3-way to control a bathroom fan.

Now, I'm trying to figure out how I can synchronize the LEDs on the new switch to the first switch.

Are there any apps that allow for simple logic and changing whether the button LED is on/off?

I'd want to button LEDs to be off if the fan is on and vice versa.

Any help is much appreciated!

I’m not aware of any apps to do this. It is relatively easy to do in Rule Machine for the Zen32, maybe something similar might work on the Zen30?

Here’s a screenshot of one of those rules I use on the Zen32 to sync one of the button LEDs with the state of a group of lights:

Look for an app called One at a Time, you will find it at HPM. It does exactly what you want!
