Siri Shortcuts support in iOS app
Having IFTTT support is awesome, but IFTTT response times can be slow.
Since iOS 12, apps can natively support Siri Shortcuts. Apps such as the one we use to control our robots can nominate common commands as shortcuts that users can activitate via Siri. This means you could start, pause and stop cleans via Siri voice commands, all without having to set up IFTTT.
You could also get more creative and incorporate these commands into your own shortcuts and combine them with HomeKit commands.
