I have an original Bloomsky (Sky 1) from when they were doing the introduction of the unit. My first unit lasted 60 days (Feb.-Apr. 2016). They sent me a new unit after returning the first one to them at no cost. That unit is still running, BUT, the temp/humdity sensors work when they want to, and mostly they are incorrect. I use the camera to check the weather at home with the App. I would question their long-term reliability based on my experience.
As for setting one up. It is pretty straight forward.
