There’s now a CarPlay app for the Home Assistant Companion app on iOS. This means that it’s possible to control (some) of your devices connected to Home Assistant whilst driving.
I like CarPlay, and have a standalone unit in my car. Most CarPlay apps are designed for either navigation or for listening to audio content whilst driving, but Apple has allowed some other apps more recently. For example, the RingGo parking app is now available in CarPlay; I wish the same could be said for the four other parking apps I have installed.
The Home Assistant app has four tabs: Actions, Areas, Control and Servers. Areas gives you the list of rooms that you have defined, and from there you can access some of your devices. Control gives you a big list of all of the devices that have a function that can be controlled whilst using CarPlay – mainly buttons and switches. Meanwhile the Servers tab is there in case you’re able to log in to more than one Home Assistant instance.
Actions are unique to the Home Assistant Companion app. They link to automations, but have a specific trigger. At the moment, I’m only really using actions to control my Nest thermostat as this is usually the only thing I want to control outside the home. Actions are also used by widgets on iOS, and by the Apple Watch integration. They’re a bit of a faff to set up at present; this video seems to be the best guide to setting them up.
It should be noted that Home Assistant also supports Android Auto, and indeed has done for longer. CarPlay support was new in January but it’s taken me until now to get it set up and remember to take some screenshots.
I’m really happy about this new feature, as being able to safely control my heating whilst driving isn’t something I’ve been able to do before. It makes the time that I’ve spent setting up and tweaking my Home Assistant server worthwhile.
