Hello

First, it would be helpfull if the Display would be shutdown after some time to lower the energy consumption.
with about 4Hours at Bettery I won´t say that is Mobile. It should at least work a Day without charge. Because the most Time out it only have to measure and write to SDCard without looking someone too it.

Second, It would be good if it could automaticaly synch the Data when it gets an Internet Connection.

Third, It sghould not delete the SDCard data after sychronizing. But should write all measuements to the Card in a fifo manner.

fourth local access to Card via W-Lan or USB, to copy the Data to a local DB or CSV File via Script.

Thanks,
