For anyone interested in how they can monitor battery statistics from their Pylons directly, I've created the following Node-RED flows for this. I'm very new to Node-RED, so any constructive feedback is welcomed:

You need to change the device/ unit ID on the inverter to 1

Hi all,

It's been almost a year since I started using these NR flows, and had no issues to date. However, this week I had my installer update my Sunsynk firmware, and now the flows are no longer working. 

These are the errors I am getting. Any idea where to start troubleshooting, or what might have changed in the more recent inverter firmware?:

Awesome, that did it. Thank you.

For future posterity, it is the "Modbus SN" setting in the advanced menu. Will require a restart of the inverter to take effect,

Yes, it works. The only issue I ran into was that I wasn't aware of the diffirence between DIN and Samite. The P1 being DIN, and my DB being Samite, it was a bit of an issue getting it to fit, but there are adapters available foer this.

Hey Saliegh.
 
My recomendation would be to install HA OS: https://www.home-assistant.io/installation/generic-x86-64

Once done, install the Node Red add-on from the included add-on store.
Then you can start with the flows in this thread.
 
I also recomend the Everything Smart Home channel on Youtube. Loads of useful guides for HA on there: https://www.youtube.com/c/EverythingSmartHome/featured

Managed to get it working via MQTT.
Changed the Assemble config to the following

 
Added a timestamp inject that injects every 24 hours.  Date/ Time Formatter uses a pallete called moment
 

 

flows (9).json

Ok, something's gone wrong, and maybe you guys can help me figure it out. The above values stopped working at midnight last night. My guess is it has something to do woth the last_reset? Maybe I need to be passing it a value at midnight to update it as having re-initialized?

I think you could do it on Home Assistant using the Riemann sum integral  https://www.home-assistant.io/integrations/integration

I have updated the flows to include the PV2 Panels and generate a total power figure if you want to check it out and perhaps upload it to your github as well as my Solar Dashboard (always under construction). Perhaps we could start a project with everybody involved, would be cool to enable Bloubuls original flows with the reading/writing of the load shedding options 
flows (4).json Solar Dashboard-1621923466176.json

I've used @jacauc's examples, and added solar nodes to it, as well as changed/removed the calculated nodes for those who have both essential and non-essential loads on their inverters. For anyone who is interested: https://github.com/juanhaywood/sunsynk-modbus-nodered-flows

Yes JuanH, I agree 100%, buy that  @Bloubul7 a Bells 🙂 , I definitely couldn't have done it without all his hard work

Be aware that it will change some of the names of the tables in your influxdb, so dashboards may be affected. Let me know if you need help transferring data from the old tables to the lowercase tables.

Forgot to mention 🙂

Thought I'd share my current flows for anyone interested.
Removed all Solar Readings (nodes) as I do not have PV (yet) Split the data output into a separate flow to simplify changes Set msg values for each of the nodes so they can be reused later Cycle through each reading one by one to avoid parallel requests to modbus - seems to work a slight bit better. Format MQTT topics using the home assistant MQTT discovery protocol, to allow HA to pick up the entities automatically https://www.home-assistant.io/docs/mqtt/discovery/ Feel free to comment - I'm not exactly a node-red or MQTT expert, but this seems to work for now.
