 The application uses vibration to confirm the action has been requested, as opposed to the 'toast' appears to show the action has been successfully executed. This is enabled by default but may be turned off if you do not desire this behaviour.
 
-The application timeout prevents the HomeAssistant App running on your watch when you have forgotten to close it. It prevents the refreshing of the menu statuses and therefore excessive wear on your battery level. For those users who prefer to keep the application open all the time for continuous use, they can reduce the battery wear by increasing the "poll delay". This inserts a user configurable number of milliseconds between each item's update check, hence reducing the API access activity. This also reduces the responsive of the statuses displayed when HA devices are switched externally, i.e. by another Home Assistant client, then the watch menu display will not update as quickly. Therefore if you only use the HomeAssistant App briefly now and then, keep this setting at the default 0 seconds. NB. There's a minimum of 50 ms in ConnectIQ timers, so anything less and the value here is forced to 0 ms which turns this feature off completely.

 There is a second timeout value for confirmation views. This is intended for use with more sensitive toggles so that the confirmation view is not left open and forgotten and then confirmed accidentally without you noticing. **We cannot advise you this is safe, be careful what you toggle with the watch application!**
