Thought I'd share my journey of integrating data from the SolarCloudSystem/EG4 API directly into Home Assistant using custom sensors and scripts. This approach bypasses alternative solutions that rely on LuxPower or Solar Assistant, providing a direct connection to the web API ( e.g...

Reposting from https://diysolarforum.com/threads/eg4-rest-api.98576/post-1381231 ok so the first attempt at custom integration has started... https://github.com/twistedroutes/eg4_inverter_ha using the api from https://github.com/twistedroutes/eg4_inverter_api I haven't written the readme...

You can use monitor.eg4 as an API. Here's an example I wrote https://github.com/garjarbinks/eg4mon

Let me know what your logs show! Also, I just finished the first version of the API: https://pypi.org/project/eg4-inverter-api/0.1.1/

TY

I know how to do the writes but I'm hesitating until it's been used for reads for a while. My main issue is that I have only seen the API responses for the 12000xp and would need to see a few other models to ensure I'm writing the right things. Then I also have to find the source for the value...

Sounds like you have the right settings... I assume you're using the correct port. For me, battery had to be set to 0 or 1. Maybe throw in some images to confirm the orange cable is in the right place, dip is correct etc?

Here's my python API/SDK https://pypi.org/project/eg4-inverter-api/0.1.1/ I'd you need an insomnia collection or an openAPI spec, I've got those too. I posted some highlights of the discover process in another thread. I'm new to eg4 and only have exposure to a single 12000xp that has no grid...

I am working on adding this to my ESP32 "Weather Display" along with my Generator data from genmon:

Sometimes there's a timing issue and you have to "wait" or force run it again. Try a refresh of the configuration files from the developer section (not a restart). I'm just re-writing the API as a python package today, and will then figure out how to create an HA Integration that you can just...

middle row for EG4... nearly there... I've found a few slight improvements to the auth which I'll update in my script when I get time.

For s***s and giggles I have been playing around with adding data from my EG4 web monitor to my ESP32 based weather monitor. This uses the approach I posted elsewhere in this form to get data from monitor.eg4... via REST(like) and display on the screen. Q: Would be interested to hear what...

Would be interested to hear what CRITICAL info they would want to see on such a display. It's probably less than this, but maybe not. I am also considering adding a dedicated EG4 screen for additional details.

No problem

You can do the same with just NAT, DNAT specifically. I have a rule in my router that traffic FROM my network TO 10.10.10.1 should be translated to 192.168.x.y (x.y is the singles IP address)

Ok, I just added parameter read and write. Will test and upload later today

@mondurr https://pypi.org/project/eg4-inverter-api/0.1.1/ I'm working on a HA integration to use this.

ok so the first attempt at custom integration has started... https://github.com/twistedroutes/eg4_inverter_ha I've got to write up some tests, validate the data scaling (e.g. where EG4 provide 5100 to represent 51.00 V), likely create a few virtual sensors (a sensor made from other sensors...

that's a great idea actually, as I am only using one pair of terminals on the 12000XP right now!

Do you get a "login.json" created?

Hi everyone, I’m setting up 4x EG4 Wall Mount Indoor 280Ah Batteries with an EG4 12000XP inverter and would love some feedback on my design before finalizing it. I want to ensure that I have safe, balanced, and efficient power distribution while also selecting the best busbar and overcurrent...

eg4-inverter-api (Python) I may take a look at incorporating LOCAL mode at some point, but that's a lot of modbus to decode. lxp-bridge is no longer maintained, so I'm thinking this cloud approach to the API may be the way for now, but I'll keep a view to adding a local mode in the future. I...
