Leviton Smart Dimmer and Alexa: what to say to control brightness/dim value?

Yeah I would exclude the dimmer from HE and then factory reset. You need to hold down the top button nfor at least 15 seconds, you will see it flash red and the light will go off.

I would also forget all devices in Alexa and have it rediscover.

Yippee - that did it! Thanks for the suggestion! I've been doing IT for so long that I should have questioned whether the dimmer really got a factory reset after the upgrade... Still learning, even after all these years :slight_smile:

Yeah I did that to all my dimmers when I updated, it was a pita because I have so many but they have been working great since.

BTW - do you happen to know if there's a way to configure this Leviton dimmer thru HE's GUI? I'm talking about options like minimum light level, max level etc. I know I can do it at the dimmer itself, but thought it would be nice if HE exposed all the settings in its GUI...

Yes use this driver, it has all the advanced config options. You also always switch back to the stock after you configure the dimmer.

Make sure after you save the settings you hit "configure" to send the settings to the switch.
