Hi,
I've purchased two Caseta dimmers and one standard Caseta hub. I also have a Google Home / Google Assistant voice control system (Google's version of Amazon's Alexa).
Since Google Assistant and Lutron Caseta can't talk directly, I'm using IFTTT to allow control of the dimmers by voice using Google Home (AKA Google Assistant).
To achieve this, I've created one scene for both dimmers to be on at 70% and another scene for both dimmers to be off (using the Lutron Android app).
In IFTTT, I've set up two applets - one accepts a voice command in Google Assistant to trigger the dimmers to 70%, and the other applet accepts a voice command in Google Assistant to trigger the dimmers to turn off.
I find that the dimmer response to IFTTT isn't very reliable. Specifically, I've had trouble getting the dimmers to turn off using Google Assistant and IFTTT. Sometimes the lights go off, sometimes they don't. The problem appears to be between IFTTT and the Lutron hub, since I can control the lights with the app and since Google Assistant gives the proper response. for example, I can speak the command to Google Assistant, it gives me the proper response "OK, turning off the lights", but the lights stay on (the dimmers don't respond. To date, I haven't had any problem turning the lights on - it seems to work correctly. It's just the off command that is unreliable.
I've only had the system running for one day, so it could be more unreliable results could pop up over time.
Can Lutron / anybody help to find root cause why IFTTT command to turn off the dimmers is not reliable? Is this a bug between IFTTT and Lutron? Can Lutron release a software patch and push the software update to the hub?
