Combine Waste Collection Dates with Personal Duty Calendar

[Tockra]

Hi everyone,

I’m using the Home Assistant add-on to import waste collection dates, and it works well for getting the official pickup schedule. However, I also have a separate calendar where I mark the days when I’m personally responsible for taking out the bins:

I’d like to combine both calendars into a single sensor that only notifies me when there is a waste collection and I am responsible for it. Has anyone done something similar or can suggest the best way to achieve this in Home Assistant?

Thanks in advance for any help!
