Ashley’s Light Fader 2.0✨: fade lights and/or color temperature with your choice of easing (curves), including ease-in, ease-out, and ease-in-out

@acdown87

I got one light working amazingly… but in parallel, one turns on and fades, the other turns on and stops at 1%. Any ideas?

Hi, @acdown87!

I think there’s a good pretty chance that you might be experiencing the same issue that @Sim209 was running into.

In short, I think your lamp might be fibbing a bit:

@handcoding

1. The script asks the lamp to set itself to 1 brightness.
2. The lamp then processes that set-brightness command.
3. The script then asks the lamp, “What’s your current brightness?”
4. At this point, the lamp should reply to the script with “I’m at 1 brightness”—because that’s what the lamp’s brightness should be if it had actually processed that set-brightness command—but instead the lamp replies with “I’m at 0 brightness.”
5. So from there, the script exits early because it thinks that the lamp had been turned off.

If you might be interested in confirming that hunch, you can do so by enabling debug logging and then running your fade:

1. First, if you haven’t yet installed the Home Assistant Log Viewer add-on , install that. (This should add a “Log Viewer” item to your sidebar within Home Assistant.)
2. Then open the Log Viewer in one of your browser tabs. And then in a second browser tab, open the automation with your test fade.
3. Then within the automation with the test fade, enable Debug Mode within the options for Ashley’s Light Fader.
4. From there, run that fade, and while the fade is running, switch over to the browser tab where you’ve got the Log Viewer open.
5. You should see some debugger output within the Log Viewer that looks something like this:

(I’ve sliiightly reformatted the below log bits just for clarity.)

And if you might like, feel free to share an excerpt from your debug logs, and I’ll be happy to give that a look.
