Costs credits to use your sensor – Ember by Cercacor Review

Your sensor comes with a number of "free measurements" but afterwards it costs up to 3 credits (1 credit is 1 dollar) to read all of the data. The device itself is already pricey. Charging an extra few dollars to be able to get all the data your sensor can read is a predatory price model that's really not customer friendly.
