Something similar not sure if it will work for your case is Tasker and Sharptools. Since you can subscribe to the garage door state, you can make Tasker prompt you for action. It’s not directly integrated but close
I used to text IFTTT to close garage door when I was getting notification that it was open for 15 minutes. Later I changed to SharpToolsand Tasker, but then Alexa and Alexa Listens came along and replaced everything.
IFTTT allows you to trigger an action based on an SMS message sent. However, it may not be specific enough for you, because your choices are “Any SMS sent”, “Any SMS sent to a specific number”, or “Any SMS sent that matches text”. You clearly don’t want the first of those. The second might work if closing the garage is the ONLY thing you ever want to do by text - ANY message you send to the ST text shortcode will fire your garage door close action. The third is a bit problematic - you could match on “close garage”, but then it would fire when you sent a message to ANYONE that had that text in it - such as if you told another family member, “Don’t forget to close garage when you leave”. You could probably work around that if you were willing to include some text string that you would be very unlikely to use in any other messages, such as “#ST# close garage”.
