Grid meter: energy reverse vs total energy reverse

[nunojpg]

I have a custom grid meter that sends data to dbus on /Ac/Energy/Forward and Reverse.
Currently forward is always 0 so let’s focus on Reverse.
I get the expected and correct values in “Total Energy Reverse”.
But the field “Energy Reverse” is showing the symmetric change (negative) of “Total Energy Reserve”.
“Energy Reverse” is not available in the csv or xlsx exports.
What is it, and why is it negative?

VRM is receiving “deltas per configured reporting interval” from the gx.

These are the reverse/forward fields:

The Totals are the actual forever forward incremental counters of that device.

@dognose

deltas per configured reporting interval

I now tested that this is related to the time-period selected (Today, 7 days, etc).
I still think it is weird that it is negative as it is not a negative forward, but a positive reverse.

Yes, that’s a “side-effect”. Summing up all the deltas of 7 days will be the amount forwarded/reversed in that 7 days.

(This is also where the system graph concludes the hourly bars from. Think it has been choosen negative for mathematical reasons there, to be “in line” with the momentary grid power)
