what is totalloadpower

[santiagozky]

Hello, First of all, thank you for this. it's been very helpful!

Im having trouble understanding what the sensor totalloadpower is. looking at the SAJ portal it seem to indicate the power being drawn by my home (from getPlantMeterEnergyPreviewInfo ) but in HA this seems to be reporting only the self consumed load. e.g. If Im loading 1kw from the grid and 1kw from my panels, I was expecting totalloadpower to report 2kw, but it just reports 1kw.

Is this a bug or or Im just not understanding it's purpose. Which sensor contains the total load being drawn by my home?

Hi @santiagozky, good question. I do not own a H1 of SEC module and cannot really tell you to be honest.

Maybe @Confushion , @faanskit @robshot can answer this question?

[RobbieDemaegdt]

I will write it down to check it out tomorrow.

[RobbieDemaegdt]

@santiagozky I'm looking at my totalloadpower and that is the total grid power + total solar power. So I'm currently having 446W of solar power with 552W of the grid and my total load power is 998W. I don't know why on your side it doesn't show the 2kW but that is indeed what it should show and how it's working on my setup.

[santiagozky]

thank you for clarification very much. It then seems to be something on my side.

[santiagozky]

hello again! I was debugging this and it took me a while (Im new to HASS and Python). I think my setup might be different from yours, because in my case it seems the totalLoadPower is coming in a different column in getPlantMeterChartData.

Checking my requests and comparing to my graph in https://fop.saj-electric.com/saj, I see that totalLoadPower matches the second column, not the third. the columns I get are:

0- PV power 1- load power 2- self consumption 3- export power 4- import power

which matches the order in my UI :

Looking at the code it seems those don't match to the code expectations. That's why I was am only seeing the self consumed as if it was the total. Im assuming other people get different columns? (maybe battery?)

I dont have an H1, I have a R5 (rebranded as Greenheiss) with a sec module.

[RobbieDemaegdt]

I have the same order as you in my web interface, so I don't think that order affects how we receive the data. I'm not sure why the data is not in the same order, I would suspect that the rebrand doens't matter either.

Currently I'm very busy but I might look into rewriting a part of the code to also support the realtime info. Don't expect the changes soon probably even only next year.

[santiagozky]

I dont think the rebrand is the issue either. I access the SAJ branded portal (the rebranded portal is http://inversores-style.greenheiss.com which just has a different color). I changed the code locally to feed from column 1 instead of 2 and now I get the right readings. I could open a PR, but if Im the only one with this issue I suppose there is something more in play.

[RobbieDemaegdt]

Do you have a battery system? Else somebody is creating a new integration which could be working for you but there is no battery support for now. https://github.com/djansen1987/SAJeSolar/discussions/45#

[santiagozky]

I dont have a Battery. for the time being Im happy leaving things as they are. I have a private fork just adjusting the columns as I receive them and it works well so far. but would be nice if it was clarified if there is a difference in data between battery and non-battery systems to better improve this.

[RobbieDemaegdt]

normally there is no differences as I have a battery setup but other people that are helping here which don't have this and it's also working.

[santiagozky]

Just to be clear. this is what I changed locally in sensor.py after inspecting the contents of https://fop.saj-electric.com/saj/monitor/site/getPlantMeterChartData

I do not have an answer to this, but looking into the plantChart2.js code, I take note of the following different titles:

var titleArray = [PV_POWER,LOAD_POWER,SELF_POWER,SELL_POWER,BUY_POWER]
var titleArray = [PV_POWER,LOAD_POWER,SELF_POWER,SELL_POWER,BUY_POWER,BAT_POWER,"SOC"}
var titleArray = [PV_PRODUCTION,CONSUMPTION,SELF_ENERGY,EXPORT_ENERGY,IMPORT_ENERGY]

The behavior seems to differ depending on what is sent as input in chartDateType in the /getPlantDetailChart2 endpoint. E.g.

if(chartType=="2"){//发电功率/发电量
if(chartType=="3"){//发电效率

• 发电功率/发电量 translates to "generating power/power generation"
• 发电效率 translates to "power generation efficiency"

So, it appears as if the request may differ for different systems. I think the way forward is to capture (in Chrome) how the request looks for @santiagozky compared to other systems.

In particular, the /getPlantDetailChart2 is what needs to be traced and compared, I think.

I think the key to this is hidden in the respons parameter pvType:

Again, the clues are in the plantChart2.js code:

if (data.pvType == 12) {
  for ( var k = 0; k < dataCountList.length; k++) {

} else if (data.pvType == 4) {
  for ( var k = 0; k < dataCountList.length; k++) {

if (data.pvType == 3) {
  for ( var k = 0; k < pvDataNameArr.length; k++) {
    if ((k >= 4 && k <= 12) || (k >= 16 && k <= 24)
      || (k >= 28 && k <= 36)) {

} else if (data.pvType == 4) {
  for ( var k = 0; k < pvDataNameArr.length; k++) {
    if ((k >= 5 && k <= 12) || (k >= 17 && k <= 24)
      || (k >= 29 && k <= 36)) {

So, by looking at the pvType parameter from a few different system, this is an easy fix.

HTH/Marcus

[santiagozky]

the input chartDateType is 1 for "day" since it's graph is different than "month" and "year" which are graph bars. if you switch from today to month you'll see a second request with chartDateType.

Honestly, it seems to me like this is a bug, but appears only if you don't use the h1 sensor.

If you defined the H1 sensor the totalLoadPower is taken from sensor.py line 1100:

                    if 'totalLoadPower' in energy["storeDevicePower"]:
                        if energy["storeDevicePower"]['totalLoadPower'] is not None:
                            self._state = float(energy["storeDevicePower"]['totalLoadPower'])

It seems that if you have a battery, that data comes from the storeDevicePower object.

If you use the saj_sec sensor, it comes from line 1165:

                if self._type == 'totalGridPower':
                    if 'dataCountList' in energy:
                        if energy["getPlantMeterChartData"]['dataCountList'][4][-1] is not None:
                            self._state = float(energy["getPlantMeterChartData"]['dataCountList'][3][-1])
                if self._type == 'totalLoadPower':
                    if 'dataCountList' in energy:
                        if energy["getPlantMeterChartData"]['dataCountList'][4][-1] is not None:
                            self._state = float(energy["getPlantMeterChartData"]['dataCountList'][2][-1])
                if self._type == 'totalPvgenPower':
                    if 'dataCountList' in energy:
                        if energy["getPlantMeterChartData"]['dataCountList'][4][-1] is not None:
                            self._state = float(energy["getPlantMeterChartData"]['dataCountList'][4][-1])

this comes from request to /getPlantMeterChartData. You mentioned /getPlantDetailChart2 but that seems to be for the photovoltaic generation only (the "home" tab), not energy monitoring ("load monitoring" tab).

Looking at /getPlantMeterChartData, when using chartDateType=1. it has a dataCountList object with columns for this titles [PV_POWER,LOAD_POWER,SELF_POWER,SELL_POWER,BUY_POWER]; (line 347 of plantMeterChart.js).

But again, looking at the code above, it expects

• totalGridPower in ['dataCountList'][3] (but should be 4)
• totalLoadPower in ['dataCountList'][2] (but shoud be 1)
• totalPvgenPower in ['dataCountList'][4] (but should be 0)

@faanskit do you use h1 or saj_sec sensor?

[faanskit]

the input chartDateType is 1 for "day" since it's graph is different than "month" and "year" which are graph bars. if you switch from today to month you'll see a second request with chartDateType.

Ok, makes sense.

@faanskit do you use h1 or saj_sec sensor?

Neither, I only have a R5 system without SEC.

Honestly, it seems to me like this is a bug, but appears only if you don't use the h1 sensor.

Bug or feature. What I try to [help you] figure out is if there is a condition that can be used to report differently for different systems. From the discussion, both appear to be correct - but depending on configuration (what system and modules you have)

It appears as if this integration considers H1 and SEC as mutually exclusive. I would assume you can have a SEC installed also for a H1 system. vol.Optional(CONF_SENSORS, default="None"): cv.string, What happens if you configure both? My assumption is that one will be overwritten, which can be the source of this bug/feature.

What happens if you change order of them in your configuration.yaml?

I think the root cause it that H1 is considered to be a module, when in fact it is a Hybrid Inverter. Sure, since H1 has a battery it has additional measurement points than e.g. the R5 series.

The SEC however should be considered an optional module, that works both with R5 and H1 systems.

I do not have a solution, and honestly I don't even have the relevant systems. But I gladly bounce ideas.
