It does what it promises. Unfortunately, if you put it on a pi, it is relatively close to the processor and I don't know to what extent it affects temperature measurements. It works once, of course, it is a bit expensive for what it does in my opinion. But I recommend it for anyone who wants to play with python, javascript, and any other application for dashboards. I played with shiny server and plotly. I opened a port, set up a DDNS, and I can see the measurements from the internet.
