Sunsynk + Home Assistant

With Solar Assistant you do get the energy dashboard. Any chance you'd be looking to sell one of your Pis?

I am using Solar Assistant and sunsync and when I saw your HA screenshot it looks the same. So my question is did you ever get your Solar Prediction to closer match the actual - Mine looks the same - The peak and shape is good, but about 2 hours too early. Was thinking of tweaking the angles to maybe try delay the shape?

No i didn't - but to be fair i didn't try to get them matched..
 
Help!! My HA has stopped seeing my solarman - it is not updating any sensors. Any ideas?
 
Were can I get a step by step guide on how to connect Sunsynk inverter to Home Assistant using the Kellerza addon?

I installed the sunsynk addon, aswell as Node Red. Then connected the inverter using the adaptor as per instruction.

So what now? How do I display the readings etc?

Are you new to HA, or only the SunSynk integration?
 
New to HA.

But I managed to impprt my sonoff devices, other smart devices, etc.

So is it more a thing of learning HA?

I thought it would be easy to at least view the sunsynk sensor readings somewhere in HA, without starting the complex stuff like building routines etc?
 
What does this integration give me more than the existing sunsynk app?

Do you have the SunSynk or Solarman dongle?

The new Sunsynk dongle. As far as I know this one cannoct be integrated with HA.

Thats why I went the Kellerza route. But the instructions srop at importing the Sunsynk and Nodered addon and linking the Pi with inverter with the rs485 connection.

Is their a step by step guide for what to do after that to view the sensor data?

Once you have the add-on working then it shows up as a Device and shows all related entities (sensors) underneath that.

If you want to add it to your energy dashboard you need to do some leg work to combine PV1 and PV2.

I’ll try find some time today to give you all the settings I have.

So my Sunsynk Add-on looks like this...

It goes without saying you need MQTT setup already for any of this to work and I highly recommend using the /dev/serial path directly to your FTDI cable because the USB port addresses tend to change upon reboots in Linux.

Once that is all working it will show up as a Device via MQTT.

And under that will be all the sensors specified above.

Now the only real problem with the Sunsynk is that it has no output which combines PV1 and PV2 and therefore you need to make one and so the below lives under my sensors.yaml file.

Code: 
  - platform: template
    sensors:
      pv_power:
        friendly_name: 'Solar Energy'
        value_template: "{{ (states('sensor.pv1_power')|float + states('sensor.pv2_power')|float) }}"
        unit_of_measurement: "W"

Which then creates a sensor.pv_power entity and you can now go plug that into the Energy Dashboard along with all the other sensors for grid input/output and battery charge/discharge.

It seems I have a lot of homework this weekend. :)

Mine does not show up as a device. I have not set up MQTT . Let me try this first later today. do I just add MQTT integration via setup/add integration, or what must be done thereafter to map/communicate with the inverter?

Thanks

Yeah you can just setup the built-in HA integration and then feed the Inverter add-on the username and password.

@SauRoNZA can you share a pic of the physical setup ? Curious to see how it looks.

I have the solar assistant running on a Pi, at the inverter and my current handiwork makes the entire setup (which is a thing of beauty) look like crap.

I need to install an enclosure to 'hide' the pi .

TIA

I get the error below. Does this mean something is wrong with my wiring/connection? Or is there some setting that is incorrect? Any assistance is much appreciated.
