[SOLVED] Alexa notification after sensor open > x Minutes

SmartApps & Automations Automation Ideas

Hello

I’ve spent a few hours searching for an answer and come across nothing. When a smarthings door/window sensor is opened for > x minutes I want Alexa to tell me so. There are scripts for sending an SMS - but the trouble I’m having is triggering Alexa - has anyone with the exception of Rboy figured this out?

You can open a virtual sensor and use that to trigger an Alexa routine as the final step of whatever your logic is.

This used to work really well with the original smartthings skill. Then they changed the skill a few months ago and now it can be flaky for some people. But it’s worth a try.

Here’s the FAQ:

Thank you.

Using original code by Smarthings “Left it Open”, I created a new routine and virtual switch - then updated the SMS code in the Left it Open, added code to flip the switch and that than triggers the Alexa routine to speak along with sending an SMS to me. Thanks for the idea and if anyone wants the code changes I made, happy to share.

Schaffer,

Can you please share the code changes. This is exactly what I am looking for now.

Thank you!
