Multiple IFTTT inputs and Stringify

[rainyday_505]

Curious, I have devices that work in IFTTT but are not yet supported in Stringify. The functionality for IFTTT is too simple for what I want to achieve. Therefore, I was thinking of something like this:

Create 2 separate IFTTT applets. In both applets the THAT is to run a Stringify applet. Then when both are TRUE use the output of Stringify to run a 3rd IFTTT applet.

What I want to do is AND 2 IFTTT applets together in Stringify then run a 3rd IFTTT app from Stringify. In another thread it looks like I can bring at least two IFTTT applets into one Stringify flow. What about more?

Here's where I'm confused at how it will actually work. Will Stringify hold the state of the incoming IFTTT applets?

Therefore, when one IFTTT applet triggers, Stringify will latch this TRUE state at the input of the AND and wait indefinitely until the other IFTTT applet triggers and supplies the other TRUE state to the AND function?

Being these inputs are coming from IFTTT which is waiting for a trigger I'm unclear on how Stringify will act. It's not like a time widget that can always be checked.

Ultimately, if this works and I can AND two IFTTT apps in this manner together, the next step in the flow will be to trigger another IFTTT applet for my final outcome.

Just to be sure, think along the lines of: if the door open AND the alarm is set, tell the hub to shut the door with all device that are only supported by IFTTT and not Stringify (yet! One device mfg said it's on their radar).

Thanks!

If you connect two IFTTT things together like you are suggesting, whichever one triggers first will start your flow, it won’t wait for the other one.

You will need to use variables to accomplish what you want, using the Functions:Variables Thing.

Have each input IFTTT Thing in a separate flow, and have each one set a variable to true when triggered. Each flow can then use an ONLY IF trigger (in the Functions:Variables Thing) to see the value of the other IFTTT variable to decide whether or not to close the door.

So you could make a Stringify flow with the IFTTT Thing that triggers when the alarm is set (assuming you can look at that in IFTTT). It would set an alarmset variable to true… then ONLY IF the dooropen variable is true, close the door via an IFTTT Thing that goes back to IFTTT.

You would need a second similar flow that uses your other IFTTT input to set the dooropen variable to true. That one could then close the door ONLY IF the alarmset variable is true.

Depending on what kind of door it is and what kind of motor is closing it, you might not want to close it as soon as it opens, since it might close on whoever just opened it.

You will also need to set the variables back to false when the door is closed or the alarm is turned off.

Here is a link to some sample flow setups so you can see how the Only Ifs are set up. Notice that the Things used as Only Ifs connect to the yellow dot on the line coming from the When thing.

Hi Gary,

Thanks for taking the time to answer this question. I believe the Functions:Variables Thing is the key to creating the functionality I'm after. That really opens up a lot of automation possibilities.

Thanks again!
