Boot up issues related to ethernet connection #51

Closed rebekahlolsen closed 10 years ago

Unless the raspberry pi has an ethernet connection plugged in, the bootup will not continue to the visualization start. I thought the plugs talked to the zwave chip in the raspberry pi, but apparently it is still set to communicate over internet.

@Anton04 Could this have to do with your script that tries to get the latest code from GitHub?

I am still having a hard time navigating this github system. I get emails with your responses but I don't know what they are responses to. Anyway. I think this is the biggest issue still. I saw the other changes, and they are great. Thank you so much for adding the real time measurements by color. This will be super helpful. I will try to update a kit that I have at home to see if it will update the code from github with the new changes. I will also see if this works over wi-fi or if I have to hard wire it.

This seams to be working now right?

So the Z-wave thing stores values and their time stamps. It you boot without ethernet the clock on the RPI will not be set correctly and there fore we could be in the situation that we have stored metervalues that are in the future this makes the z-wave software go bananas. I disabled the time update on the raspberry pi. Also since we have a read only card all stored values in the Zwave will be the same on each boot. This error caused some kits to freeze depending on what the latest time was that was stored in them in the last network connection.
