Why no All in one testing?

[lrlivingston]

Why doesn't the reef community have a all in one testing gadget? Just your main elements. I have a saltwater pool and they have this thing that sits in the overflow and tests daily 5 different chemicals and temp and sends it to an app. Seems odd Hanna doesn't make an all in one.

I imagine your pool generally needs less precise readings than a reef tank does.
