Sig Energy System Integration

Third party integrations

So,

i had tried some of the provided settings and created a custom one:

My SigenApp gives me:
Daily total: 18,69 kWh
Charging: 8,82 kWh
Discharging: 5,2 kWh

and this is the information in HA using the modbus integration:

i have tried it for the last 2 days. i am stock.
I don’t know what is missing, i just getting this:

Maybe somebody would be able to assist me?
THank you.

We’d need more information about what you’ve done.

  • How are you running HA? HAOS, Docker, etc?
  • Did you install the modbus_sigenergy.yaml from here?
  • Did you follow the instructions on folders?
  • Did you restart? Did you create the dashboard described here?
  • What exactly is the problem? I can see you have one metric on a dashboard you created. Is it accurate? Does the history look about right?

sadly not yet in contact with the installer seeing if the mod bus is okay

Hi there,

There is a known issue with double counting and this might be your issue. The solution is to not poll the modbus so often (which is why the energy value is being double counted). The author has updated the code to reflect this but I accept that it might not be readily accessible. Here’s the discussion thread on it. There’s also a summary here.

Responding to you looks like it may have also helped me. I’ve been having random shutdown’s without any notification. It appears I’m not the only one and it may be associated with firmware updates.

Hope this resolves your problem.

my “Set Sigen Independent phase power control” was set to disable and the result was:
I had 3000W to the grid and I wanted to use a single phase device with 2000W.
With setting Set Sigen Independent phase power control to disable the 3000W was splittet into 3x 1000W per phase (A, B & C).
So I used 2000W on a single phase (B) has was in result: 2000W to the grid via Phase A and C and 1000W from the grid on Phase B.
Result: 1000W from grid to be paid

with Set Sigen Independent phase power control “enable” the Sigen stor was providing the 2000W i was going to use on a single phase (Phase B) and the remaining 1000W was splittet to the rest of the phases (A and C) and pushed into the grid. So the function seems to be important to avoid usage from the grid.
Result: the 2000W device was using the full capacity available and only the reminaing power was pushed to the grid.

That is very important if you have a “Phase-accurate counter” in German known as a “phasengenauer Zähler”.

@HomerHH Thank you very much, so it enables the battery plant output to balance the phases’ power. This is indeed crucial if you want to reduce grid consumption and Maximize self-consumption, which is my primary goal and the stor’s settings. So I’ll keep it on “Enabled”

At the moment i’m facing some miner problems with the “Sigen Daily Grid Energy import”.
Every night it is set to 0kwh but hours later is is bumping up to some “random” values. Today it is jumped at 5:40 in the night to approx 5,5 kwh. But there was enough energy in the Battery.
Someone else are facing the same issue?

Hi Tim,

A: HAOS
B: yes
C: yes
D: yes

But I have just started all over with a new HAOS setup.

Might be best to rewrite your question with all the information in one place. Describing the problem and your setup well in one post makes it easier to help you. Include error messages and logs as appropriate.

Hello! Just got a Pointguard system provisioned today, and had the installer toggle Modbus on. I figured out its IP from my router’s UI, and got everything set up in HA from the TypQxQ GH repo, which did produce a ton of new Sensor and Helpers, but it doesn’t seem like they’re getting data. I scanned the IP with nmap and I don’t see port 502 (or anything else) open? I do have their myPointguard app set up on my phone and it is getting data (not sure if the app talks directly to the hub over the LAN or they both go back to Sig’s servers). Is it possible they’ve changed to using another port, not 502?

94

Just setup a new inverter. I have noticed that the ModBus TCP server only runs on the WiFi IP address, and not the LAN IP. I have both connected, and both reply to pings.

nmap <wifi-ip> -p 502
502/tcp open mbap

nmap <wired-ip> -p 502
502/tcp closed mbap

Currently trying to get SigEnergy to confirm if its their problem and whether they can fix it!
