• If you're inexperienced with smart home products, their functionality, and benefits, the HomeKit ecosystem may appear intimidating and perplexing, but getting started is actually very simple and clear.
• This may sound apparent, but make sure the HomeKit device is turned on, because you won't be able to use any HomeKit gadget without energy (yet anyhow, HomeKit is futuristic, but we're not that far into the future).
• The next popular troubleshooting technique is to switch off the HomeKit device, wait 10-15 seconds, and then turn it back on.
• The issue is sometimes the iPhone, iPad, or Mac running the Home software, rather than the HomeKit gadget itself.
• Simply switch the iPhone or iPad off, wait a few seconds, and then turn it back on, waiting for it to rejoin to the same Wi-Fi network as the HomeKit device before proceeding.
• Because all gadgets rely on the internet, you'll want to double-check that the wi-fi network is up and operating.
• Checking the internet connection from multiple devices is a good way to make sure the wi-fi is working.
• Make sure the iPhone, iPad, or Mac is connected to the internet and connected to the same Wi-Fi network as the HomeKit devices.
• Ensure that the iPhone, iPad, or Mac is signed into iCloud and that the Apple IDs are the same. iCloud is required for HomeKit and the Home app to work.
