Hey all!
I'm looking for ideas of the "best" way to group energy consumption so that, on my Energy Dashboard, I have like "Lighting", "Appliances", etc rather than each specific device consumption.
Some things that occured me were:
carmine estuary
Personally I use labels for this
soft dome
OK so I just realised that Groups are way better than what they used to be.
If I simply create a Sensor Group and add the Energy Entities I want, that's it. All done.

Yep, I just cba to change over. The summation groups are nice
soft dome
Indeed

If any of those entities ever reset their value you're gonna have a bad time. There's no good way to combine total_increasing sensors... but it can be done in very limited situations.
sand rapids
yeah not clear. Summing power is 👌
soft dome
yeah that, I'm summing W
all I need is a quick overlook of how much energy I'm using on lighting and such
if I ever need the details I'll just look at each entity one per one
soft dome
well that certainly didn't go as planned
I don't get that 71.79 though
worst case it should be 14.46 no?
soft dome
OK so I reckon this thing is doing a sum of each individual measurement
What am I missing here!?
My entity stats seem to be correct but the energy dashboard is going crazy

You sound a bit confused and I'm guessing you are mixing up power (W) /energy (Wh) in some way. They don't mean the same thing and cannot be used interchangeably.
Please give exact details on what entities you created, what they were sourced from, and be specific about the state and attributes of each source, and any customizations you have done.

OK so they're all Shelly modules and I'm using the Energy entity (kWh).
Using the UI I've created a Group Helper - Sensor, added all the required modules "*_energy" entity (again, in kWh) and set it Type = sum
soft dome
yeah sorry my bad, it was a typo!
I mean _energy
you can see on all screenshots, everything is in energy (kWh)
sand rapids
ok, as I said above, summing energy entities has a lot of pitfalls
if any of the entities reset to 0, it will break the sum, and probably cause a huge consumption spike
soft dome
yeah and I get that (and probably will end up giving up going on this route and do some sort of template instead) but for me the weird thing is if you look at the helper entity stats it looks fine
But when you look at the same interval on the Energy dashboard it's all over the palce
Simple math seems to imply the Dashboard is summing each individual statistic value:
sand rapids
afaik those numbers are change values.
so your statistics believes it is increasing by 14.4 with each datapoint
that's how it's supposed to work, but you have bad data
Make a plot with a statistics graph card and you will see the same thing.

I have to say I'm super confused by now @sand rapids
If I "have bad data" what am I supposed to do then?
And how?
sand rapids
The best advice I can give is just don't try to sum energy sensors.
