Anyone experience with connecting a Growatt solar-inverter?

That’s a good idea. I’ll investigate.

Hi. I tried a usb extender but it didn’t work.

Yeah, that’s not going to work, as my ISP has me on CGNAT.

And yes they do support a fixed IP solution, but first of all, that cost more than Nabu Casa and second, my internet is paid for by the company i work for, and i am not able to get them to sponsor the fixed IP, and since they are the costumer at my ISP, i am not able to get a fixed IP, as i am not technically the costumer.

I had heard about this solution, but was aware that it would probably not work for me, sadly.

Hi

@hmadsen, with duckdns you don’t need a static IP address from your ISP as far as I know. I’m not sure what CGNAT is however i don’t think it will make a difference. I don’t have a static IP and I followed the setup and i’ve been running it for 6 months now with lots of ISP IP changes and it still works. Thanks Brett

But you do need a public IP. With CGNAT you have a private IP usually in the 10.0.0.0/8 range. Your provider runs a NAT firewall behind one single public IP. This she’s not work with any solution except a VPN your a server which had a public IP.
Mobile internet usually has CGNAT I use thuis in my mobile home with home assistant. I use the addon
SSH tunnel and forwarding to create a tunnel to my home server and connect trough there. If you know someone with a server and a public IP this will work…

Hi

Exactly, the WAN IP my router gets is 100.92.xx.xxx so clearly CGNAT.

The only solution that seems to work with CGNAT is Nabu Casa and while i actually would want to support them, i have to say, the price it cost, for me is not worth it.

I have to pay 78 USD per year (The 65 USD yearly fee is not available as i am in the EU region)

Not that it matters, 65 USD is also to much. Out of the integrations i have in HA, about 50% of them have their own app, that i can access that system via, and it is mainly “Control IHC light” and a few other small things i would gain, and as said, that’ just not worth that kind of money.

If they were 30 USD a year, maybe i would do it, but at more than double of that, it’s just too expensive.

Just to bring this back to the inverter;

Is this integration possible whilst having the inverter banned from communicating to the outside world? As in; is the integration data locally sourced, or is it pulling it through an online API?

Hi @trixxr what are you referring to here?
If you’re referring to the https://solar-assistant.io/ thread that’s being discussed then yes, you can completely isolate your system from the internet and the Growatt servers.

If you’re referring to the Growatt Integration for HomeAssistant then no, the way the integration works is by pulling the information directly from the Growatt Servers after it is pushed from your inverter.
This is exactly the same way that the ShinePhone app works on your phone, we just reverse engineered the API calls to make them from a python client instead of a mobile device.

Hey,
Did you ever get a chance to look into accessing the smart meter data that’s available, when using the SDMxxx?

Thanks. :slight_smile:

I have a Growatt re-branded inverter that uses server.pvbutler.com instead. Can it be added to the dropdown? Thanks.

Good morning,
I’ve just installed the HA Growatt intergration after having solar installed today.
However it only seems to have 6 entities, just wanted to check if this is correct?
gw

I have nothing relating to the batteries at all.

There has been issues with the growatt servers in the past couple days unfortunately.

The reported issue is: Growatt_server integration not working in · Issue #80950 · home-assistant/core · GitHub

Thanks @Tuxinator94
Had a look through the issues and seems my SPA3000 inverter is not supported at present, that’s why i’ve only got 6 entities.

Hi All, just for those of you waiting on an update on things.
There is a fix/hack available for Growatt_server integration not working in · Issue #80950 · home-assistant/core · GitHub if you want to take a look and get things working in the meantime until the official fix is released, this comment specifically details what to hack to make it work: Growatt_server integration not working in · Issue #80950 · home-assistant/core · GitHub

@DaveUK83 - RE The SPA3000 inverter, I was planning on sitting down this week and consolidating all of the tickets that are outstanding and creating a new forum post with them all, but the complete drop-out in functionality had to take precedence.
I’ll be collating the list soon and publishing it for everyone to vote on what should take priority for implementation. That said, there are some systems that have been in the queue for a long time and I made promises a long time ago to fully implement, so I will be prioritising those above all others.

Hi All,

This is a massive cross-post on all the Growatt tickets so apologies for it’s generic format. I’ve collated all of the open issues and prioritised them here: Growatt Integration - Prioritised List of Features for Implementation/Fixing

I will be working through them in order and updating that post as well as the affected tickets. Using that method I can be sure to correctly track everything associated with the integration.

Watch this space!

Sorry for the late reply, but thanks a lot!

I’ve been very hesitant to invest in infrastructure pieces that originates from areas of… geopolitical concern :smiley: But it does indeed seem like Solar-assistant could solve this issue.

I fundamentally really just hate needing to poll an internet service, to get access to information that is created locally. It very much goes against the appeal of HA for me!

But again, thanks a bunch for the lead!

Have a look here then :slight_smile:

I agree, and with the very poor performance of growatt servers it would be even better to be able to rid oneself of the dependency of them.

If only the " Raspberry Pi Zero 2 W" was not eternally sold out, i would certainly buy one and the solar assistant and be done with the sillyness that is Growatt servers.

I have several automations that rely on the Growatt sensors, for example some that will turn on certain things if i produce enough solar myself, but with a 5 minute update interval, and the posibility that they will tinker or have their servers be crap, and me having energy intensive equipment sucking grid power, because Growatt does not update my sensor, it would be very desireable to have 1 second update interval, from my own internal source.

OT, but just as a workaround, you can use EM clamps like the one from Shelly to see the amount produced.

Sure, but i want to have a figure that is “Produced, minus used”

If my solar panels make 1000 watts, and i use 1000 watt, there is no surplus solar and my automations should not run any of the “Only when there is surplus of X Watts”.
