My repo for the custom commands I run when I stream. I use the deck board app with OBS.
My Stream Timer
I use My Stream Timer by James Montemagno. I do not own an Elgato Stream Deck to configure it to launch on my streams. So I created an app extension that launches and initiates My Stream Timer. Download My Stream Timer through this link.
I use Deckboard for managing my stream deck. You can find the download link here.
After installing My Stream Timer and the extension from here.
Below I show an example of how I configured it to launch My Stream Timer with Top of the Hour countdown argument.
You can then launch from your mobile app and it pops up like seen below
