Not exactly.

Describe the solution you'd like
I am looking to integrate my PagerDuty schedule with HomeAssistant. I stumbled on this project and it looks like you're most of the way there. Ideally, I'd like to be able to create an HA sensor based on whether I'm on call or not and I'd like to be able to trigger an event when I'm paged. I'd use these to trigger reminders when I leave home w/o my laptop or would turn on my bedroom lights when I'm sleeping to get my attention. The automation would live in HA's world, but it would be nice if I could flow the events out of this project. MQTT or webhooks would make this pretty straightforward on the other side (and it would benefit people using other home automation software).

Additional context
Nothing against your beautiful UI, but this feature could be purely headless.
