With this release, the free usage limits are changed. Each new account is in free trial mode by default. Every account is provided with 5000 free measurement data sample points. These points can be used to evaluate the service in full.
The limit for only single sensor is removed for the free usage. Also the upload rate of 15 minutes is gone and the maximum of 1 minute upload rate can be used. Once the free quota has been consumed, the service will not accept any new sensor data until valid subscription to the service exists.
