I like the Aqara hub and the temperature sensors. I use it to automate a smart outlet to turn on a fan to ventilate my AV cabinet. It works great!
Curious though. The built-in speaker for that Aqara hub. It looks like it has a built-in alarm that works in Aqara, but puts an alarm tile in the HomeKit to turn it on and off. Can I trigger that alarm based on a non-Aqara event (in my case a non-Aqara door sensor exposed to the HomeKit)?
