Growatt SPF 6000 ES Plus Local Data Logger for Home Assistant

Configuration
1

Hello everyone, I am looking for something that works with my Growatt SPF 6000 ES, locally. I don’t mind getting rid of the Shine Wifi stick. The Open Inverter Gateway doesn’t support SPF yet and even the Solax Modbus integration.

I had something earlier when I used to use SRNE (SRNE inverter integration help ) and it worked perfectly. I hope I can get something similar to it.

I have a Waveshare RS485 to ethernet converter I got earlier that’s at home. I am getting a new router (G.iNet Flint 2) and ethernet adaptor so I can bypass my Starlink router to use the new router.

I plan to explore getting the Modbus data over TCP and into my HA setup, similar to what’s here. Hardware, diagrams and code would be helpful in my journey. Thanks so much.

search for “grott” in the posts and/or github

I installed Grott using the Grott Home Assistant Custom Component in September but I ended up having this issue of not getting the full data I am supposed to get from the Grott MQTT dump.

I think it could be because Grott doesn’t fully support the SPF 6000 ES Plus yet. This issue on the repo is yet to be sorted. Grott 3.0.0 not working fully for the SPF type yet (still WIP in most popular solutions on HA).

Also, Grott having to wait on the 1-minute update frequency of the Shine Wifi stick. It would be much better to get rid of it. I used to get <5 seconds update interval on the SRNE then.

I cannot really bake cake of that 2nd issue and not sure if it is limited to the add-on… I have a container running fine but admittedly with a different type.
And wrt to the 1st one, if the integration needs to pick up on data-elements, this is them to sort it out but your screenshots donot show if the data ends up in MQTT before they hit HA…each step requires code inverter>grott>mqtt>ha

This is the Grott stable add on

This is the data from the Grott Home Assistant Custom Component (grott) I get in the end.

I actually just followed the steps listed on the readme step by step. I would prefer something that works without relying on external dependencies.

From what I see two options:

  1. the data is not transferred to MQTT > issue with Grott
  2. the data is in MQTT but sensors are not created from MQTT > you can manually add them

Check the data in MQTT first
