I am trying to show a summary of total current power consumption using the SUM functionality. But I don’t get it working. The TotalPower item is never initialized (always shows “- W” although all power values in gPower group are available)
In items file I did:
Group:Number:SUM TotalPower “Gesamtleistung [%.1f W]” (gPower)
In sitemap file:
Text item=TotalPower {
Frame {
… }
}
You have to add your power items to the TotalPower group. Making TotalPower a member of gPower only makes it a peer to your power items so there is nothing for it to sum.
