An example API-middleware/SMS approach to chaining IFTTT recipes conditionally.

• Get the Google App Engine SDK (for golang).
• Clone this repo into your /path/to/go/src directory
• Copy config.go.example to config.go
• Enter your Twilio/IFTTT info into config.go
• Run it! $ goapp serve

The Google OnHub router just got a new IFTTT integration. Google/IFTTT challenged my brother and I to come up with a as many integrations as we could using the OnHub and a huge box of smart-home stuff.

See the video here: https://www.youtube.com/watch?v=JPH74ZHDuCI

With IFTTT you can trigger recipes from the OnHub when a) a device joins the network, or b) when a device leaves the network. We cooked up a lot of basic recipes around that premise. But we were also interested in using the OnHub as a kind of situational monitor to do more complex recipes like:

IF the Nest camera senses motion, AND nobody is on the router network, THEN sound the D-Link siren!

IFTTT doesn’t support this kind of contextual chaining out of the box. But we found you can patch independent recipes together with a little middleware magic. So, the above recipe becomes:

IF kylePhone connects to the OnHub, THEN post request to https://ifttt-glue.appspot.com/onhub/connect/kylePhone

IF kylePhone disconnects to the OnHub, THEN post request to https://ifttt-glue.appspot.com/onhub/disconnect/kylePhone

IF brendanPhone connects to the OnHub, THEN post request to https://ifttt-glue.appspot.com/onhub/connect/brendanPhone

IF brendanPhone disconnects to the OnHub, THEN post request to https://ifttt-glue.appspot.com/onhub/disconnect/brendanPhone

IF Nest detects motion, THEN post request to https://ifttt-glue.appspot.com/nest/motion-detected

IF SMS received with #alarm in body, THEN sound the D-Link siren!

This API will keep track of who's on or off the network, and conditionally send an SMS trigger when nobody is home... to sound the alarm!

I discuss the approach a little more in a blog post here: https://medium.com/sea-salt-ventures/google-onhub-ifttt-81ebc2e60c24.
