That's true, so sounds like a nice compromise that also follows the official pattern in a way.

That actually sounds like a good implementation. What are technical aspects of using websockets in the background? Or is it just due to battery?

Not the biggest deal-breaker, so polled is good enough for me since it is a low priority channel for me anyways.

Oh yeah totally agree with you. Got a Google Coral stick the other day after waiting for OK prices and it's a really nice game changer if you have cameras around the house. Managed to get notifications when my cats are nearby, all through Home Assistant.
