Hi,
I tried to play around with the openhivescale_v4.8.ino and then I want to compile it.
During this process I got the following error messages:

This is in file _time.ino in line 305 (void GetNTPConfigureRTC(IPAddress& timeServerIP) {)

Could you please tell an absolute arduino beginner, where and how I can define the variable IPAdress?

Maybe, I have the wrong version of the Time lib (I use Time-1.5.0)

Thank you

Michael

Hi,
I have observed that the measured weight oscillates up and down.
After changing the battery I tested the system first without any weight and then with about 27 kg.
The scale measured the following data:

So my questions are:
Is there a problem with my system?
Is the possible solution to measure twice or three times and take the mean?

All tips are welcome.

Thank you

Michael

Hi,
is it possible to read (and add it to the url) voltage of the batteries?

Thank you

Michael
