Smart Home Mower Guide

Device TYPE

action.devices.types.MOWER Interactions with mowers may include starting, stopping and pausing mowing, docking, checking the current cycle, locating the mower, and adjusting various modes and toggles.

This type indicates that the device gets the mower icon and some synonyms and aliases.

These traits are recommended, if applicable to your device. However, you are free to mix and match from all available traits to best match your existing product functionality.

Sample SYNC Request and Response

This is an example using the device type and traits above. It is intended to give an idea of how to build a SYNC response. If you add or remove traits, this will need to be modified to reflect those changes.
