I've been wanting to use multiple raspberry pi zero w with sensory hats to feed data to a central home monitoring system. Would be a fun project.
It is! Especially if you want to write the code yourself. It's an interesting design problem if you start to consider cases where the PI may be offline (mobile on a battery in my case). Do you lose that data? Store and forward? In memory or to a local data store? It's a fun rainy-weekend project.
Word of caution - HATs can be a rather inaccurate in their temperature monitoring. The Pi gets warm. I had done my work using a PTC thermistor that was distanced from the Pi itself. I've got a friend using a HAT and it's been very off (up to 10C above ambient!). A Pi Zero may not give off as much heat as, say a Pi4 though. YMMV.
