Thanks for posting and thanks for sharing a screenshot of your dashboard! I love the color scheme!
You might be able to have the rule update an attribute on a device with the number of seconds left. Basically, the rule would have to ‘tick’ every second as it counted down and update a device with the number of seconds remaining. Then you could use the Hero Attribute tile for that thing and display the custom attribute which is showing the number of seconds remaining.
I put together a custom driver for another user that allows arbitrary values to be ‘written’ to a device so they could display them in their SharpTools dashboards. In theory, you could use that device as both the trigger for the countdown as well as for displaying the countdown.
One challenge might be the timing of how fast Hubitat is able to push out the updates. The display of the timer value will probably be a second or so behind the actual ticks in the rule… so that may or may not work for your use case.
I have a variety of dashboards for different needs, but I’m really enjoying the new calendar and RSS feed integrations for my wall mounted dashboards. I’ve started making my wall mounted dashboards a bit more ‘sparse’ so I can enjoy the background images while still having quick access to ‘at a glance’ information and quick frequently controlled devices/rules.
For example, on my phone, I have one dashboard I primarily use as a navigation screen - it has some high level information like weather, time, and quick controls for mode/HSM… then the other tiles are dashboard tiles that link to other dashboards for controlling specific things. For example, my ‘security’ items are on one dashboard with PIN protection - eg. locks/garage doors.
Hey Jason - Did you ever end up making this countdown tile? I’ve been thinking about attempting the same thing, only I’m thinking about showing a countdown to show you how long you have until the siren goes off when you’ve triggered the alarm
