Your first option is to have a smart light that turns on when the door is open. This would be your indicator in the evening that the door has been left open. You could do this using a Wyze Bulb or Wyze Plug (coming soon) and the Wyze app, or a you could use a third-party smart bulb or plug that you trigger using IFTTT.
For a more elegant solution, I recommend checking out this fantastic post that outlines how to use apilio.io to do something very similar: Advanced IFTTT use without an engineering degree. (Step by step guide)
Here are the specific steps you’ll need to follow for your slightly simpler case:
A. On aplio.io, follow the steps outlined in that thread to establish a Boolean Variable, a Condition, and a Logicblock for the Garage_IsOpen logic, Omit the IsHome portions, and do not select “Automatic evaluation” in the Logicblock.
B. Create four IFTTT applets that do the following:
- Set the Boolean variable to true if the contact sensor opens (IF Wyze THEN Webhooks using a GET to the Apilio “Set true” URL)
- Set the Boolean variable to false if the contact sensor closes (IF Wyze THEN Webhooks using a GET to the Apilio “Set false” URL)
- Trigger the apilio Logicblock at 10 PM (IF Date & Time THEN Webhooks using a GET to the Logicblocks evaluation URL)
- Trigger a phone notification if the Logicblock has a positive result and sends a web request to IFTTT using the Event Name you selected (IF Webhooks THEN Notifications)
Using these steps, you can have Apilio track the state of the door (something IFTTT can not do) and at 10 PM ask if the door is open. If it is, you’ll get a notification on your phone.
Either way, good luck!
