@cp2023 thank-you so much for forking the great work originally done by Gary. I have so many automations that rely on SOC and PV. Mine is now working after deploying your updated NR and also needed to redo most of the configuration, but entities are 95% there, will iron out the rest soon hopefully. Ultimately, I need to connect directly as it seems Sunsynk want to keep giving us breaking changes. Thanks again.

Hi there thanks so much for this.

Im not great with node red but I think i Have done all the new steps just confused with sndata and sunsynksn_flow?

Sorry also confused with the Yaml file when you say needs to be in the right order? How do I know what the right order is?

Is the service down again? Getting a 500, this was after I had it working yesterday with the gdwaterworth fork

Needed to reinstall since HA seemed to be corrupt.

Getting the below, is Sunsynk changing things again @cp2023

Looks like they have changed the authentication again, I updated to match the website request and now get: {"code":115,"msg":"Invalid login interface request!","data":null,"success":false}

Was hoping to wake up and see that it was working but alas ☹️

Looks like the whole SunSynk API is down? Authentication no longer succeeding across the board. Any official announcements?

The API is working. There were more changes to the token and authentication processes.

The crew for the SolarSynkv3 add-on implemented an update yesterday. That solution is currently working for sunsynk and other generic pv.inteless dongle setups.

All of these solutions are all still so fundamentally flawed relying on the cloud for data access.

I need to start moving my friends and family over to direct local connections.

Saw the problems earlier.

I suspected this was going to be coming for a while. I think addons like mine caused problems for them and this is their way to remove them

Sunsynk as a brand with their Crap support is running their brand into the ground

In my opinion it is worth the effort to go direct, I only rely on this for the event notifications like faults etc. the rest is via a direct RS485 pull.

Shortcut if you ever consider the move and what I did was I kept the config and just mapped the corresponding sensors in the config to the direct sensors instead of the consolidated node-red source then you don't need to redo any cards and automation's as the sensors stays the same just the data source is replaced.

The event notifications was a nice to have but I can life without it in HA.

@-cK- is there a guide anywhere for this? i actually bought an RS485 converter a while back but have never got round to setting it up. looks like now might be the time to do it!

I have to agree on this or if you have to use : 

GitHub - martinville/solarsynkv3: Integrate your Sunsynk account with Home Assistant for real-time solar energy monitoring. Track power generation, battery storage, and grid usage while enabling smart automations and custom alerts. Optimize energy efficiency, reduce costs, and stay in control with seamless remote access and intuitive dashboards.

They took it to where I wanted to, but didnt have the time to invest 

If I ever got sunsynk again I would go direct.

I created something that was needed at the time, but there are far better solutions now

Even Solar as a one in all solution I now realise I can live without

In a rental. Have access to a small solar install that basically powers lights.

Geyser/Stove etc are all on Gas.

Keep a 5kw battery pack for work stuff. I can run 3 days on it.

Cost was minimal. If I have longish power downs I just charge up the battery pack with the genny.

What we realised is if we can cook / shower / work and have lights the rest is ~meh~

i copied the fix from solarsynkv3 and applied it to my fork (https://github.com/cpether/Home-Assistant---E-Linter-Logger---Sunsynk), so this should be working again if anyone wants it.

Getting some info now thank you.

Is there a issue with changing settings with the updated version or do I have a setup issue somewhere?

I take it you want to setup the kellerza addon? Think I used this videos on Scoobs youtube channel:

Note your inverter's modbus is usually set to 0 but needs to be set to 1 and if you have to change this in my experience this will trip the inverter just give it a few minutes to clear the alarm.

This has been working great thank you - you're right, it was just auth, the rest stayed as-is. I honestly don't mind the cloud reliance as long as it's reliable (it actually has been for the last few months after their infrastructure move) and it doesn't change (like it did in this case). My understanding is that the revised auth process was to improve security - which is fine but only if we know in advance it's coming.

hi

what's better to use this node-red integration or the "Sunsynk v3 addon" implementation with a dual inverter setup?

thanks

Been looking at how to do this whole thing better

Forked off the Sunsynkv3

Looking at pulling all the data into MQTT under HA then setting up a config file to create some auto entities via MQTT with the required info.

Problem is my Sunsynk is no more so I cant get data

Can someone share their plant to mine under [email protected]

So Far :

I have been working on the next iteration of Solar Monitoring

High level it will Consist of the following addons:

1. Scraper that gets the solar information and populates it in MQQT

   I have allready completed a bare bones of this one running under : https://github.com/gdwaterworth/sunsynkmqqt

   I forked SunsynkV3 and changed it 90% to do what I want

   Only prerequisite is the MQQT addon

   

   

2. Processor which then take the MQQT data and creates topics in MQQT that will then be processed as MQQT discovery and create entities in Home Assistant

   TBD

3. A MQQT listener that will look at changes coming from topics in HA and then set those topics back on the inverter

   TBD

I have chosen this route to be modular so in the future I can add in modules that talk to various inverters and you just implement the modules needed.

@Gary Waterworth Shout if you want access to a couple of different site variations. You should still have my email address.

I have access to a 50kw HV 3 phase, dual LV 3 phase and a LV single phase.
