I'm glad that we built our own (thanks again Naaz! ❤️ )
For people without the time or inclination to build their own, this could be a good solution.
I think I still prefer the hand-made one because its an opportunity to learn hardware/IoT skills.
And in addition to streaming the data in real time (which the product version doesn't have),
we can include other sensors like light and temperature in a hand-made one.
