Bugfix: Added the link on the login page to change a forgotten password

By submitting your email address in the password forgotten form, you receive an email to reset your password.

Export time format is in UTC date/time

We got some questions about the export option about the date/time field used in the export. All our exports make use of the UTC date/time. We added information to the Data Export form to explain the use of UTC date formats.

Release notes v43

February 14, 2018

Added option for submitting alarms

We are delighted to introduce our option for alarming. The backend software for submitting alarms generated by our Complex Event Processor is developed. This enables our users to define alarms. Alarm rules can be defined from the Alarms top menu on exceeding device/sensor values with an mathematic operator. Users are notified about alarms by email. In the upcoming releases we will format the notification emails and enable notification by SMS.

Bugfix: Data export within Internet Explorer fixed

Data exported from Windows with Internet Explorer resulted in an error message. This is fixed.

Showing data labels on GPS map 

On the GPS map te last measured value is shown above the GPS sensor symbol, this allows for a fast overview of all measured values from a GPS map. Only one data label is shown, in upcoming releases we will update this to show all labels.

Added "Email Yookr Support" option in account menu

Also in the near future this allows us to alarm based on multiple correlated events.

Introduction of the Yookr Default Data Format 

Definition of the default Yookr data format to be used internally between the different services we use and also with systems providing data to Yookr. This data format makes is easy for data providers and partner to integrate with Yookr.

API input filtering for malicieus code

All API input fields are checked for malicieus code and all malicieus code will be filtered out. Although our product is setup in a way that it is not vulnerable for malicieus code via the API, we added another layer of security to exclude possible future hacking possibilities. 

Changed some forms to comply with the updated security measures

With the change of the security model we introduced, some additional measures needed to be taken. For example Profiled editing needed to be improved.

Bugfix: Property editing of a graph widget with only 1 sensor

Editing the properties of a graph with only one sensor ended up in displaying no values at all. The graph widget code is rewritten to solve this issue.

Bugfix: Sometimes graph values display lots of decimals because of rounding issues

Some graphs display lots of digits in stead of a rounded number. This is fixed by limiting the values to 2 digits.

Bugfix: Fixed refresh issue with graph widget
