Identification of timers on different devices.

How much time was left on my kitchen HomePod bake timer. I happened to have my phone in my pocket, my watch on my wrist and airpods in my ears. I asked Siri out loud, in my airpods I heard there were no active timers. This despite my homepod lighting up. I had to take out my airpods before my homepod would tell me the timer status. I don’t know if watch or phone were overriding the answer from HomePod. How do I get timers shared or active timer status on all my devices?
