Smart plugs are pretty cheap as long as you want them to work with Google or Alexa. HomeKit on the other hand requires more expensive smart plugs. However, with Siri Shortcuts, you can make Kasa smart plugs work with Siri without HomeKit.
To make it work, you’ll need some Kasa Smart Plugs. Once you have them setup in the Kasa iOS app, head over to the iOS Shortcuts app. Create a new shortcut and select the Kasa app. Once the app is selected, you can set it up to turn on or off a device, play a scene, or change the lighting color/brightness if you have a Kasa smart lightbulb. Give your Shortcut a name and then save it.
Now, you can ask Siri to run that shortcut and control your smart devices.
I have this working great to turn on and off some lights and will be setting it up with the Christmas tree this Holiday season.
Kasa smart plugs and Siri Shortcuts are a great combination even if they don’t work with HomeKit.
