Thank you I had forgot about that link. Been without internet for awhile.  I  hope I can remember what all it took to get this going on the raspberry pi 1. it was nice since it worked off the 12volt battery system and I could just connect via wifi to it.

Well Tom,
I can't remember on the Raspberry pi if I had to do something extra. Elder age I guess. Anyway when I try to execute the dailylog in either powersystem/bin or powersystem/tools I get an modbus error of Illegal_data_address? I seems to remember this and see on this thread that I had bad paths before but I have checked this time and all programs except this one are running. Any ideas?

update tristartRam is working just fine.

In powersystem.h, did you set the paths for the log files and the html files before you compiled the programs (make)?

And I thought retirement was going to give me more time to play. LOL  Anyway I feel stupid again. Paths were fine I had a typo on my first executable line in cron. That made nothing work. All back up on the raspberry again. This time I am going to make a back-up of the SD card just in case this happens again. Wonderful job on this again. I really do use it when I am boondocking. And in two week I go for a two week stay so just in time. What I like the best is I can tell by the charts what times I start charging in the morning. It helps me understand early on if I will need the generator or not for the day.

Tom,
I knew there was one thing I had to change that is in powersystemstatus.c

line 217
fprintf(htmlfile,"<tr><td><img src=\"vvarray.png\"></td><td><img src=\"viarray.png\"></td>");

changed to:
fprintf(htmlfile,"<tr><td><img src=\"panelmeters/varray.png\"></td><td><img src=\"panelmeters/iarray.png\"></td>");
