Can I set an alarm on Alexa or Google Home by sending a text message, through integration such as IFTTT?
From the ifttt website, the integration all seems to be driving actions through Alexa or Google Home, I am looking for ways to drive actions on Alexa or Assistant. https://ifttt.com/amazon_alexa https://ifttt.com/google_assistant
At Alexa I am sure you can't do it with the Alexa Skills Kit currently at Google Home I think you can't.
The simple Problem here is that both device react only on user voice for the normal developer.
At Alexa a Notification system is planned or already there but it seems that it can't be used by the normal developer, from Outside. So you can't send anything to the device. Only if the device request Something like after an Intent it can push this to notifications and even for that i am not sure.
What you can do is built your on Alexa | or maybe Google Assitant device with the Alexa Voice Service | maybe Google Assistant tools (dialogflow, action sdk etc.) but there you have to do all handshakes by yourself.
