Great pieces of kit.
Perfect for keeping track of the temperature and humidity in our comms cabinet, and the notifications work perfectly for warning us when things go out of range.
I had a look at the API, which is extensive, but realised that the app and web console did everything we needed without having to write a single line of code (I had expected to write my own notification logic).
It'd be great if you had an EU distributor to simplify the process of buying and shipping from the US (and having to deal with import duties).
