    What is the polling interval of this thing?

      Hi Rob
      I’ve just done a test this morning on the device by first taking a reading in the living room and then placing it the freezer. In the Aqara app, in order to update the data you simply drag down on the home screen, and when I did that, the temperature updated instantly every time I ‘dragged down’, and in the test I did (with it in the freezer) i refreshed multiple times and each time the data was renewed and I could see a difference in the data. Even better, in the Home app, the temperature display changes in (almost) real time, so I don’t have to do any refresh action of any kind – so taking it out of the freezer, I could see the temperature reading increase as it happened. I hope that answers your question.

    Is it safe to say that it pushes the measured values when a peak/drop occures?

      Yes, it does seem to show the change in value on the Home app, without any intervention or refresh. However, I don’t think you can currently get notifications as such for these kinds of readings to your phone via the Home app. You can set up an automation to push a message to your phone via the Aqara app though. They have various options as to what you want to be notified of, like if a temperature goes above or below a threshold or the same for humidity. There’s currently no automation for atmospheric pressure though.

    Not necessairy in my case, i’m using it in my bathroom via Homebridge. When humidity >70% turn on ventilation. So it is of great value that it updates these values with peak/drop so that it ‘immediatly’ turns on when I turn on the shower. Thanks so far.
