Have you looked at open source smart vivarium projects? Several seem to have good front-end.

This may seem weird, but the reason I first started to explore air quality and sensors was to build a smart vivarium for a reptile.

I didn't go through with that project but it was a waking call for me. Animals need so much environment control to thrive and humans are animals.

So instead I focused on adding sensors and filters to my own home. Nothing fancy so far, just a mix of product that work with google home and smart sockets.
