First Timer - SunSynk via RS485 to USB

[RenierBoshoff]

So just to recap, it started with the some glitch on my side of things. With me learning and sorting through to much information.

Rather I will now post my progress below as I get along.

Setup = 8kW SunSynk > RS485 to USB converter > Raspberry Pi 3B with HA OS
Running KelleZA's MQTT based SunSynk addon and displaying it with the SunSynk Power Flow Card.

Current stuff I need to figure out:

1. Fix UPS essential side load displaying Grid Power+Inverter Power at the moment
2. Get Shelly & Sonoff devices to function on HA an set up some sort of Smart control
3. Help 3 Customer Friends to do the same

Cheers!

Hi. Are you running the latest version of HACS 2.0.1 ?

Hi. Are you running the latest version of HACS 2.0.1 ?

Hi!

Yes I am running the latest version.
After a reboot and some fiddling with DNS server settings I got it loaded.

Now I am at the next step, trying to get this Wave USB to RS485 Industrial Converter [https://www.robotics.org.za/W17286]
to collect the direct RS485 inverter data and display it on your Flow card...

I feel like I have no idea what I am doing even after watching a lot of videos, and reading up on the settings.

Do I need to paste this somewhere: https://github.com/slipx06/Sunsynk-Home-Assistant-Dash/blob/main/Dashboard.yaml

By the way, this is the physical connections:

Inverter RS485 Port > RS485 to USB converter (the WaveShare one) > USB port of Raspberry.

This afternoon the magic happened.
I think I got lost in the the multitude of options and methods.

But I finally got it working:

Next step will be to fix the Essential Load Reading which now shows the Grid side reading.
Obviously the Essential Loads on the Flow Card must match the UPS load on the Inverter flow diagram.

I will search around till I find it. Seems that there was a discussion about the 8kW SunSynk and that value not displaying the correct data.
Perhaps remap the Modbus address to the sensor.... hahaha as if I would know how to do that!

Cheers till later..

Updated this one to load_power

[RenierBoshoff]

Mmmmm looks like it calculates the same way as the other?

Card: essential_power: sensor.ss_load_power

[slipx06]

That value is coming from the register 178. You can try asking for help on https://powerforum.co.za/

[RenierBoshoff]

Are we looking at the correct Modbus addresses for the Load output?

[RenierBoshoff]

That value is coming from the register 178. You can try asking for help on https://powerforum.co.za/

Looks like this is Load Side total power according to the Modbus register.
I will definitely look on powerforum.

Thank you for your kind assistance! Will post results...
