Additional Tips

If your unit is running outdated firmware, you'll see an Update option next to the firmware version in the Spark app. For supported models, the update runs over-the-air (OTA). If OTA isn't supported, the app will link to a Help Center article with USB update instructions.
You can also cross-reference your current firmware version with the release notes for your Spark model to determine whether it's up to date.
