Help With Detecting Already-On Enbrighten Z-Wave Switch

c0nsumer · July 25, 2024, 8:07pm

I’m looking for some help and ideas. I have an Enbrighten Z-Wave switch in a bathroom, connected to an exhaust fan.

I would two things:

Retain local control so HA is not needed for simply turning it on and off.
Pressing the on button (or something similar) while it’s already running turns it off after 20 minutes.

Here’s my current code. The issue I’m running into with HA is that it’s starting the timer when I first turn on the fan, which I’m guessing is because:

The switch immediately turns on.
HA starts the action because of the On press.
HA interrogates the switch and sees that it is on, so it carries on.

Can any of you give me suggestions for how to do what I want?

Here’s the code I currently have, for reference:

This also doesn’t seem to do the trick. I tried to have this trigger on an on-press (works), then two wait-for things (waiting for on and off presses) running in parallel, but instead what happens is:

First on press, fan turns on.

Second on-press, LED turns green, fan turns off after N time. LED silently set back to white. (This is good/as-desired.)

Press on, fan turns on. Press off, fan turns off. Press on again, fan turns on and LED turns green, then fan turns off after N time. (This is not good, it’s as if the wait-for off and stop didn’t stop the whole action; only that branch.)

So, here’s how I solved it.

First, it turns out that these switches (Enbrighten 58433) support scene selection via long press, double-click, and triple-click.

Since I was having so many problems detecting a single-click only when on, I changed my automation to start the timer on double-click.

Code for this is as follows. Note that the one second delay between turning off the fan and setting the LED back to White is due to latency in the switch itself. If I don’t do this, the LED on the switch will flash white as the fan is turning off.

I also used this automation on off-press to stop/start the timer one (if it’s running) to reset it, and reset the LED to white. It only acts if the LED is set to green, using this as an indicator that the timer is still executing. This is to handle if the fan is manually switched off while the timer is counting down:
