</span><u><span style="COLOR: blue; FONT-SIZE: 10pt"><a href="http://powermonitoring.zzl.org/">http://powermonitoring.zzl.org/</a></span></u></font><span style="COLOR: black; FONT-SIZE: 10pt"><br><br><font face="Calibri">Its all working well apart from the daily updates which run at midnight each night (local time) and pull the KwH produced today and the Time online today from the inverter. The bottom graph from the webpage is the one im talking about. <br>
<br>My rrd database is setup as follows:- <br>--start N <br>-s 86400 <br>DS:KWH_Today:GAUGE:86500:U:U <br>DS:INV_Online:GAUGE:86500:U:U <br>RRA:AVERAGE:0.5:1:365 <br><br>Then im updating as follows at 23:59 local time (GMT +10):- <br>
rrdtool update Xantrex_Daily_Totals.rrd N:somenumber:somenumber <br><br>From what I have found In the forums I need to replace the N with something else for the timestamp to ensure that its put in for the correct day however am unsure what to put in. <br>
<br>Any help would be appreciated. <br><br>Cheers <br>Brett</font></span></p>
