My Sunsynk 8Kw & data collection setup

[CorneSchutte]

Martinisonline, I have been using use the ESPHome solution with the SunSynk 8.8kW inverter since about 10 Feb (just after my Inverter was installed), and updates are pretty immediate. Life graphs such as Inverter Power update every 2-3 s here - so I guess it is a function of when the inverter sends an update on the bus? Other data such as Battery SOC updates much slower, so I think it only sends it when the value changes?

In terms of setting write updates, it is normally also instantaneous here, but I sometimes observe  a slight lag (0,5s?), when I for example toggle the grid option for a time period, but it is not something one does so interactively that it bothers one.

I am surprised by the ESPHome device's performance (ESP32) - I have 81! entities defined on it, with absolutely no issue so far - it is running 24/7 unless I reboot/recompile to refine the ESPHome code. I had just done last night the very nice power flow that emulates the SunSynk screen -see attached screen, and had to add a few missing sensors that was not defined in the ESPHome setup.

Excellent. Like a lot the format style.

my Inverter is a Deye 5K and I'm using a solution based in a raspberry Pi with USB-RS-485 adapter and with a Solark Modbus HA integration. It is working for about 1 year flawless, with a refresh rate of about every 5 seconds.

Now I'm thinking to start to sell the surplus energy to the provider but want to do some automations to change some parameters automatically in the Inverter, specifically the battery charge rate according to time of the day and PV production.

The integration I have, doesn't have the "write" functionality, is read only.

I'm thinking to update the system and start to use this ESP32 approach to gain the "write" possibility. I have some ESP32 devices around and I did before some very simple projects with ESPHome. I've read the thread and the examples provided, but still is a bit confusing how the ESPHome intregration works and how it writes into the inverter registers.

Had a look on the version shared by Klatremis, but the registers are completely different from the Deye 5Kw equipment.

Can you share more details about your solution? ESPHome code...?

Thank you.

"My" ESPHome code, which is a combination of others work before me.

But I believe the Deye registers are completely different?

Here is the Github by @Klatremisfor the ESPhome for the 12K DEYE inverter whose Modbus registers are totally different to the Sunsynk 8kw & 5kw inverters.

Not sure which DEYE/Sunynk models Modbus registers are compatible, maybe something to do for someone with some spare time to work out

Many thanks CorneSchutte and Sc00bs for your replies.

In a short analysis, looks like your code (CorneShutte) matches my Deye 5Kw registers.

Received today the TTL-RS485 adapter, so later today is time for bricolage

One question:

How is it managed the registers that contain two words? for example the Total Grid Buy Power (KWh) contains two registers (78 for low word and 80 for high word) according to the Modbus doc. I understand that the final value is a combination of these two values, right?

Is this being managed by the ESPHome code somehow?

[CorneSchutte]

Martinisonline - the ESPHome code (as originally written by sjlouw and refined by jacauc, with the update mod by slipx), only has the following for Grid Import Total (Buy) and it works fine for me:

 - platform: modbus_controller          # 78 Grid Import Total (Buy)
   modbus_controller_id: sunsynk_esphome
   name: "SS Grid Import Total (Buy)"
   id: sunsynk_esphome_grid_import_total_buy
   register_type: holding
   address: 78
   unit_of_measurement: "kWh"
   accuracy_decimals: 0
   device_class: energy
   state_class: total_increasing
   filters: #GOOD
    - lambda: |-
           x = x / -1;
           if (x > 32767) return (0 - x + 65535) /1;
           else return (0 - x) /1;

Thus this ESPHome implementation therefore does not use the 80 register as far as I can tell? See if it works for you?

For me, the code I inherited from jacauc etc worked immediately - the challenge was to identify the correct 2 wires in the Ethernet cable to connect to the TTL-RS485, but once I had done that, it simply just worked. I had recently tidied it up and put the ESP32 and TTL-RS485 in a nice case with some ventilation slots and have had no issues. 

[martinisonline]

CorneSchutte, what I'm thinking is:

The registers have a 16bit length, which means they can handle values from 0 up to 65535. On this specific register, one unit represents 0.1KWh so the maximum value the register can record is 6.553,5 KWh. So, when this value is reached, the register goes to 0 and the "high word" or the register 80 increments.

Saying this, it will work fine until it reaches the 6,55 MWh. After that it will reset to 0 if we don't take into account the register number 80!

Maybe I'm wrong, but this is my understanding

"My" ESPHome code, which is a combination of others work before me.

But I believe the Deye registers are completely different?

I was playing with some text sensors to get the timezone to display as 02:00 as opposed to 200 etc. You can try them if it helps

 

text_sensor:
  - platform: template
    name: "Program1_test"
    lambda: |-
        int minutes, hours;
        if (id(sunsynk_esphome_setting_timezone1).state) {
        minutes = static_cast<int>(id(sunsynk_esphome_setting_timezone1).state) % 100;
        hours = static_cast<int>(id(sunsynk_esphome_setting_timezone1).state) / 100;
        } else {
          minutes = 0;
          hours = 0;
        }
        char formatted_time[6];
        snprintf(formatted_time, sizeof(formatted_time), "%02d:%02d", hours, minutes);
        return esphome::optional<std::string>(formatted_time);
  - platform: template
    name: "Program2_test"
    lambda: |-
        int minutes, hours;
        if (id(sunsynk_esphome_setting_timezone2).state) {
        minutes = static_cast<int>(id(sunsynk_esphome_setting_timezone2).state) % 100;
        hours = static_cast<int>(id(sunsynk_esphome_setting_timezone2).state) / 100;
        } else {
          minutes = 0;
          hours = 0;
        }
        char formatted_time[6];

Thought I would also contribute with something small. Not as impressive as what some of the others here but a contribution nonetheless.

The GUI for Sunsynk System Mode, or lack thereof, has really been annoying me, so I put this together. It needed to be easy to read to quickly understand what's going on, and also easy for the wife to change if needed.

It requires the lovelace-layout-card to work. For my purposes, it's also a separate view.

Hi 

Did you make any further modifications to you dashboard? I did try to add it but I get the error below and I dod have all the mushroom card installed and also the loveloace-layout-card, can you share the code if you did?

The above project is exactly what I was hoping to find - does anyone have it working on a D1 Mini?

Hello,

I notice a similar behavior and the issue was the way the variables were defined. There are some power values that are SIGNED, and other are UNSIGNED. Make sure the signed (the ones that can be positive or negative) are properly defined as SIGNED (value_type: S_WORD).

Does anyone have a list of all data types for all registers? The Sunsynk word document leaves a lot for the imagination 

[Sc00bs]

Hi @jacauc

There are the two Modbus register files that I have

sunsynk_modbus which looks like an extraction from a manual as it looks like it starts at 2.6

I also have a Chinese document that I translated with Google Translate. I think that it is v117 of  the document which was released in 2021 so there may actually be a v118 out by now but haven't seen it as yet.

 

sunsynk_modbus.pdf Modbus118 Translated-compressed.pdf

[Sc00bs]

This is the original Chinese file, I think it is actually a DEYE document

Modbus储能-组串-微逆宁波德业V118 (1).pdf

[jacauc]

Thanks @Sc00bs. I've seen those before but unfortunately it's not very clear to decipher the data types and whether signed/unsigned.

How about a small dot that changes colour

 

Hi @slipx

Thanks for the great job you've done with this card!

I took it one step further and made the battery icon and lightning bolt smart.

When the battery is charging the lightning bolt appears. The bars in the battery changes based on the current SoC of the battery.

I achieved this by overlaying three battery icons and only showing the relevant one (same way as you did with the status indicator).

[McAllstar]

Just a question for anyone who has solar-assistant integrated into home assistant via MQTT.

How many entities do you have? I think i may be missing a few

did you enable allow setting changes on the solar assistant config page for MQTT?

 

I guess what i'm asking is how to you get the prog1 time settings like the ones below 

I don't have that option, I only seem to have this option below which says Capacity point

@jacauc I sent an email to DEYE asking if they had a newer Modbus document and received a response from them saying that the V118 document is the latest version

I think i kinda figured it out.

You need to create a new view by editing one of your dashboards and then select the + icon

then i you need to select the 3 dots in the top right and select "Edit in YAML"

then i think you need to past this part of his code. After that then you can select "add card" and use the rest of his code. you need to modify the entities according to your entity names. That's where my problem comes in I'm using solar-assistant and my entity names don't match his and I'm missing the timer and prod entities.

I've made some updates to the card to include dynamic animations. It will now animate power flow based on defined conditions i.e. positive/negative battery power, zero power etc.  I didn't want to have circles moving all over the place so not all paths are animated but you can modify to suite your needs. Note the moving circle is hidden if power is 0. Here is the link to the GitHub repo

What program do you use to edit the SVG? I've been using Inkscape, and it works quite well. The one disadvantage is that it adds a lot of unnecessary code needed by the program.

I would suggest showing the absolute values of the readings since the direction of the dot shows the direction of current flow and makes the negative sign in the readings redundant.
