in the graph in sunny explorer

3 users have this problem - all having same config (smatool 0.11 ubuntu -

i've test smatool one time, but don't try more on this experience, because my 
inverter's display siappear partially, the graph of current day was erased too, 
(data was not cleared, and sunnybeam BT, have a good display)

I think this is due to setting inverter date/time
maybe we have to remove this in sma.in file

I have the same problem on my 5000TL, except the data does not reappear, the 
day's data has been cleared.

It only happened once now I look, the inverter was writing the times at 
xx:xx:44 and now it writes xx:xx:00 since the script made it 'stuff up'

I resynced my whole mysql db and now all the times are xx:xx:00 and no longer 
xx:xx:44

just had the same issue popping up. the data is still in memory, the display 
does not display any values anymore, except total power produced.
configuration : ubuntu 11.04 , SMA 5000TL
setting the date messed up the display unit on the box, although the values are 
still in the device.

is there a way to get the display back up?

Yes, I have found a solution.

On my first sync with a Database the Time offset on the inverter was changed.

After logging in with SunnyExplorer I changed the time offset back to what it 
was on and now it's been working perfectly ever since.

I think it changed it to GMT and I had to change it back to GMT +8, It does NOT 
affect any readings or times from the device like you would assume.

I have to confirm, on subsequent smatool runs, it does not clear the display 
anymore.
While I did nothing with sunny explorer, just waited to get new data in the 
display, and reran smatool a few times. since the first run, now the display is 
fine again. 

maybe its an issue when it the first run.

side effect of initialisation.

well I been running the smatool for some days now, and my display gets cleared, 
especially when I poll infrequently, as in every 3-4 hours. then the display 
goes blank again.

so basically it still breaks the data to the display unit
 trying to login with sunnyexplorer and see if resetting the time offset is a solution

small update, after using sunnyexplorer and then smatool again, the display 
returned, and has been ok since. 
even the previous data returned on the display.
Although I noticed in sunnyexplorer a discrepancy in one of the day graphs 
three days ago, where a block of data is missing ( interpolated as a perfect 
slope down, a straight between two points).

so it seems that on init something in the ordering, date is changed, but 
rectified with sunnyexplorer, can this be the problem on an empty database, 
where it does a select range beyond the buffer?

there are still some bugs in sunny explorer (1.2.7) The slope you see in the 
graph (straight line between 2 points) is one of them.
You can delete the local data (cache) in sunny explorer to force SE to reread 
the data from the inverter (sometimes a restart of SE is needed)
