The latest App in the App-Store allows to measure date and time units (seconds, minuts, …). This App helps to simplify post processing with OUT-Apps by delivering measured values that are easy to determine in test cases. Or just play with this App as an IN-App if there is no read IN-device connected to your Lufft I-BOX.
The timegen IN-App is provided for free. More info and the download can be found here.
