Added to GitHub. Also thanks @Kosmik for the template sensors and Solarman inverter definitions

Slip · May 13, 2023

@Kosmik I was busy working through the Solarman sensor mappings https://github.com/slipx06/sunsynk-power-flow-card/wiki/Sensor-Mappings and noticed that it does not have a sensor Grid External Total Power. You might want to add it to your pull request as it is not the same as 169 - Total Grid Power that Solarman uses

External ct1 is the equivalent. External ct1 - internal ct1 gives the non-essential.

I have a custom calculation for essential as well as there isntba dedicated sensore. For that I created a helper.

The revised cards from 1.20 altered my calculations a bit.

This is my card, for the version just prior to your latest. It does show a negative on the inverter when charging from grid.

It might work for your setup but you may need to sum External CT L1 Power (170) and External CT L2 Power (171) to get Total External Power = 172
Internal CT L1 Power (167) + Internal CT L2 Power (168) should equal Total Grid Power (169)

So you should use 172-169 for nonessential.

Yeah basically take both external internal cts into account ( 4 in total , 2 ex 2 in ). But one can create straight helpers to sum each of those to get the same outputs. There is likely the same codes available ( registers ) , just they aren't exposed in the solarman integration. When I got a gap I'll do a proper cross check. I think one issue was that one was a reverse negative so couldn't apply like for like. Otherwise can do another pr to the solarman integration team for missing ones like I did for the battery and frequancy.

Hotfuzz · May 13, 2023

I just got solar installed this past week. Does the novelty of checking HA and looking at this ever get old?

Slip · May 13, 2023

@Hotfuzz I like that Solar forecast card. Can you share details please

Found it https://community.home-assistant.io/t/solcast-global-solar-power-forecast-integration/334681/173

v1.4.4
Updates

Adds sensor for battery current
Adjustments to battery layout to accommodate battery current

Sparkz0629 · May 15, 2023

Im using the kellerza addon to get my stats from my sunsynk.
However, i cant seem to find an entry for the inverter current. (inverter_out_164)

These are the only Inverter sensors i have access to.

Any advise?

Don't see a total but these are the individual sensors. 166 jumps to Generator stuff.

164	L1 Inverter output current L1	R		0.01A	int Signed int
165	L2 Inverter output current L2	R		0.01A	int Signed int

also 154 is L1 specific, 155 is L2 and 156 is Total Voltage.

154	L1-N inverter output voltage L1-N	R	0.1V
155	L2-N inverter output voltage L2-N	R	0.1V
156	L1-L2 inverter output voltage L1-L2	R	0.1V

*Disclaimer* This is from the sunsynk modbus doc ( appears similar for Deye as well, tested on mine )

Not sure if this might help, but I created a template sensor

YAML:

sensor:
  - platform: template
    sensors:
       ss_inverter_current:
          friendly_name: "Inverter Current"
          value_template: "{{ (states('sensor.ss_inverter_power') |float(0) / states('sensor.ss_inverter_voltage') |float(0) ) | round(0)}}"
          unit_of_measurement: 'A'
          device_class: current

Can I be a pain and say let us be able to remove the "gridlines" in the battery box? I'd rather they float like the other figures personally.

This was a big help.

Added the custom sensor file to the addon, with the fetch of those values and all sorted.

thanks a mil

Was considering this route, but eventually decided to go the custom sensor route to pull the value directly from the inverter so less math for my HASS to do. Thanks for taking the time to respond

No worries.

Mind sharing the custom sensor ? Would like to compare the 2 ?

Kosmik · May 15, 2023

Hmmm, what if you shifted the SOC out of the "box" to a larger bolder font like the Daily Stuff under the battery? Not sure what others thoughts are on that? TBH I have a gauge under mine to highlight the SOC.

Certainly.

I only used L1 as L2 returned zero consistently.

Python:

from sunsynk import AMPS, CELSIUS, KWH, VOLT, WATT
from sunsynk.rwsensors import NumberRWSensor, SelectRWSensor, TimeRWSensor
from sunsynk.sensors import (
    MathSensor,
    Sensor,
    SensorDefinitions,
    TempSensor,
)

SENSORS = SensorDefinitions()

SENSORS += Sensor(164, "Inverter Current", AMPS, -0.1)

@Slip how can I make it bigger? I'd love for it to consume an entire panel all by itself as a quick view of what's going on.
