Personally, my biggest use of IFTTT before the Amazon echo was released was for voice control of smart things.
Smartthings has an IFTTT channel, and there is also an IFTTT āSMSā channel that is triggered simply by sending a text with a specific hashtag.
So as long as you have an unlimited texting plan on your mobile, you can have voice commands for pretty much anything smartthings can do. This works especially well with a smart watch that can send voice text.
Itās not using natural language, so it can be a little clunky. But if you really need voice control, itās a very nice, totally free way to add that functionality. You donāt need any extra devices.
I am quadriparetic, use a wheelchair with limited hand control, so this was very helpful to me before the Amazon echo became available. I do prefer the echo, because it does use natural language, but the IFTTT voice text message is still useful now when I am out of Echo range, such as in the yard.
I set up IFTTTās text number as a contact called āHouse.ā And I was then able to say āhey, Siri, tell House Hashtag bedroom underscore fan underscore onā and have the fan come on!
For more information on this method, see the following thread. Although the original author is using Siri in the example, the exact same method will work with any voice text Method including hey Google or Cortana.
