Alexa Notification with delay?

[McTechSolutions (Craig McFarlane)]

Guys.

On the Alexa app I can create a routine that when a sensor is in the open state that it has Alexa say a notification message.

Is there anything in the ST world that can do the following.

1. ST Sensor open
2. If after x minutes sensor is still open
3. Have Alexa announce something like “Sensor A is open”

Now I do use a ST app that does all of the above apart from have Alexa announce. Right now it sends a push message which is great but I am not always with my phone. Has anyone done anything like this with ifttt or stringify?

Thanks in advance,

Sure. Use a virtual sensor instead of the real sensor for the Alexa Notification. Then have CoRE monitor the real sensor and when it is open for 30 minutes turn on the virtual sensor and that will trigger the Amazon notification.

The following thread explains how that works (this is a clickable link)

FAQ: Can I trigger an Echo Action without Speaking to It?

Breaking News!!! As of August 2018, a SmartThings-connected Contact or Motion Sensor can now trigger an Amazon echo routine if you live in the US, Canada, or the UK !!! Amazon has now added the ability for some sensors to trigger an Amazon echo routine (not a smartthings routine), which does let you trigger other smart home devices which are not connected to SmartThings without having to speak an echo command! Or you can set it up so that your echo devices will speak a customized phrase, play a doorbell chime, or various other sound effects. And even better, that contact sensor can be a virtual contact sensor. And although it’s a bit tricky, a community member has created an edge driver that will create BOTH a virtual switch and a virtual sensor and keep the pair in synch. So…

If you aren’t already familiar with WebCore, see the FAQ

FAQ: What is WebCoRE? (And what was CoRE?)

CoRE (now WebCore) is a very powerful community – created rules engine for SmartThings. It allows you to set up stacked conditionals like “If A then B but only while C and not if D.” Setting it up can be quite complex, but there are many community members who will be glad to help you. For example, here is a piston that one member created to notify him if the dog had already been fed twice that day and he picked up the dog bowl for a third time. He needed this because he has a large family and people didn’t always remember whose turn it was to feed the dog. [image] The original version of CoRE Has now been replaced by a new version, WebCoRE, which moves the data entry to a web interface. This allows for flexibility and an architecture that requires more memory than is av…

Just like @JDRoberts stated, let ST be the brains and just let Alexa be the voice. I use(d) webCoRE to “speak” to tablets running LANouncer that were Bluetoothed to Echos and it worked good enough. Would have to occasionally reset.

Now I am starting to use virtual sensors for anything that is not an instant trigger. Couple more steps but still works great and more reliable than LANouncer.
