Home Assistant Energy Dashboard - Redux

[Tovrin]

I've been having issues with the Home Assistant Energy Dashboard as I was getting some strange figures that made no sense (usage seems to be heavily inflated over the Fronius inverter I replaced .... like DOUBLE). When I checked the configuration, some things have changed from when I originally set them up in Home Assistant:

• The "accumulated" friendly names seem to have been renamed "total" instead for the inverter and plant ... except for the individual batteries, which have remain "accumulated". The actual entity names seem to have remained the same. I don't understand why this friendly name change occurred, but it makes finding the correct entity in the dropdowns.
• The "Signen Plant" entity for battery discharge/charge and PV generation no longer appear. They are under PV inverter though. I hope that these suffice.
• I can't seem to find the dashboard setup documentation anymore. Can someone point me in the right direction for this please?

Anyway, this is my configuration. Can someone confirm that these are correct?

| Electricity Grid
| -- Grid consumption
| ---- Sigen Plant Total Imported Energy = sensor.sigen_plant_accumulated_grid_import_energy
| -- Return to grid
| ---- Sigen Plant Total Exported Energy = sensor.sigen_plant_accumulated_grid_export_energy

| Solar Panels
| -- Solar production
| -- Sigen Inverter Total Charge Energy = sensor.sigen_inverter_total_charge_energy

| Home Battery Storage
| -- Battery systems
| ---- Sigen Inverter Total Discharge Energy = sensor.sigen_inverter_total_discharge_energy
| ---- Sigen Inverter Total PV Energy = sensor.sigen_inverter_accumulated_pv_energy

And then I have a bunch of monitoring devices to try and figure out where my energy consumption is going.

Just to reiterate, then friendly name changes are nothing I've done. I assume they occured in subsequent updates of the integration.

Confirmation of the configuration would go a long way to try and figure out the weird strange (inflated) I'm getting.

@Tovrin Michael,

All the accumulated sensors got replaced when the integration was updated to utilise the SIG modbus definitions v2.7 a few months ago.
Prior to this update the integration was having to use calculated sensors (based upon readings from other actual SIG sensors) to provide these accumulated readings, with modbus v2.7 this added actual modbus registers to natively provide these readings.
I believe that the only accumulated sensors remaining now are the 'sigen_inverter_pv#_accumulated_energy' sensors.

The sensors your using in the Electricity and Solar Panel sections of the dashboard (above) are correct, the Battery ones are also technically correct / one possible set of sensors to use. The other options are to use the

a) 'Sigen Plant Daily Battery Discharge Energy' and 'Sigen Plant Daily Battery Ccharge Energy' or;

b) 'Sigen Plant Total Battery Discharge Energy' and 'Sigen Plant Total Battery Ccharge Energy'

.... using 'Plant' (instead of the individual inverter) in the hope of ever being able to afford to add add a second Sigenstor stack of ESS into the Gateway ;-)

$64,000 question... hence just suggesting some steps that could be done to try and work out where the issue is. :-)

Question mark if the mySigen app uses modbus to obtain this data or if it uses some 'Native API' of its own...?

Hence suggestion if MC4 plugs can (safely) be moved between trackers to see if data is reported on PV4 via modbus (but not PV3). If this did work, it would and previously youd used the QModBus app to directly query the PV3 mobus registers (thereby confirming it is/isn't the integration) then you'd know its something with the Sig itself (as there's no option to turn off registers just enable/disable modbus access).

[Tovrin]

Hmmm ... I've installed QModBus, but the UI makes no sense to me. I've figured out how to connect via TCP, but the "modbus request" part is impenetrable.

[Roving-Ronin]

You need to get the Modbus Definitions v2.7 PDF (posted elsewhere on this repo) and find the modbus register number and information (as below):

IP you should know, ID is going to be either 1 or 2 for the EC and 247 for the plant.

[Tovrin]

Many thanks (especially for your patience).

OK! Not necessarily progress, but a bit more understanding.

• PV1 and PV2 are predictably responding with the correct results (as per the entity in HA)
• PV3 is bringing back 0. This gels with what HA is recieving.
• PV4 is bringing back 65535. Not sure if that just means if the battery is not in that location or what.

As for physically moving plugs, that's well outside my wheelhouse. I'm sure the installer would have issues with me doing that.

I'm wondering if this is enough for Sigen Support to figure out what's going on?

[TypQxQ]

I'm only using PV1 and PV3 on my EC15 and PV3 is working fine for me.
Upload logs for debug when you have problems.

[Tovrin]

I take it you have only 2 batteries then?

[TypQxQ]

If you refer to my earlier image, then, I have 4 batteries.
My inverter has 3 PV (Photovoltaic, Solar Panel) inputs but I only use 2 (1 and 3).
The PV inputs have nothing to do with the batteries.
Do you possibly have another inverter connected that inputs as a "3d Party Inverter" for one string?

[Tovrin]

I have 1 inverter and 3 batteries and a gateway.

The Sigenery integration reports 1 inverter, 3 Inverter PVs (which I assumed to be the batteries) and the Sigenery Plant.

I think I understand what your getting at now. So the Inverter PVs are not the batteries, but the PV strings?

[TypQxQ]

Yes

[Tovrin]

Ok ... two things

1. Oops. So much for assumptions.

2. I guess that means I'm no closer to figuring out what those weird figures I'm getting are and why I seem to have inflated usage figures. Sadly, I don't have any of my device/energy history anymore, because I just deleted the plant and recreated it again.

sigh

Edit: Ahhh ... not as bad as I thought. Backups! (So I only lose 12 hours. phew!)

[Tovrin]

Incidentally, is there a way to see the individual battery stats?
