Support for hybrid inverters such as the Sunny Tripower Smart Energy

[andrejditz]

I have a Sunny Tripower Smart Energy 10.0 and it looks like this type of inverter is not supported.
It is a hybrid inverter with a DC connection to a battery.

I got the following error in the Homebridge log:
The discovered inverter is not a solar inverter! Please create a bug report with as much detail as possible.

Please inform me if you need more information.

Oh, interesting! This is a hybrid inverter AFAICT: solar & battery all in one? This one, right? https://www.sma.de/en/products/hybrid-inverters/sunny-tripower-smart-energy

Can you share your log output? 🙏

I get the exact error message when I hardcode my IP as recommended in version 1.1.1. It worked well with inserting it in 1.0.2. I think that has to do with querying the register codes which is new since 1.1.0.

@Scream4Life Yes, but you have 2 separate inverters, not a hybrid one. Different problem, same symptom!

[andrejditz]

@wimleers yes that is the inverter i have in use.

@Scream4Life Yes, but you have 2 separate inverters, not a hybrid one. Different problem, same symptom!

Yes, but when I hardcode the IP in the index.js it finds only the PV inverter and gives the message above. That’s why your current version does not work for my right now 😞

Yes. I am aware, as I wrote at #5 (comment). Please stay tuned as I figure this out. I'm doing all this in my spare time! Blame SMA for A) making their devices work so inconsistently, B) not providing any documentation 😞

Thanks for your offer to schedule a remote session, I will take you up on your offer! 😊

[wimleers]

@andrejditz Thanks, that looks like what I suspected! f5db4fd only looks at the device class. You're getting unknown, so it's neither a solar nor a battery inverter. That's great news!

Expect an update in the coming days.

Don‘t worry. I‘m thankful for every minute you‘ve spent with this. The solution is already great and I‘m sure it‘s getting even better over time. Next week I‘m off for holiday. Let me know when you‘ve time for a session afterwards.

[wimleers]

I literally can't find any documentation detailing all of the device classes … 😬 The closest I found was https://files.sma.de/downloads/ClusterController_MODBUS-TI-en-18.pdf, which lists:

Device class:
8000 = All devices
8001 = PV inverter
8002 = Wind power inverter
8007 = Battery inverter
8033 = Load
8064 = Sensor technology general
8065 = Energy meter
8128 = Communication products

So … I'll do a 1.1.2 release that hardcodes the knowledge of these classes and then adds better logging output so that @andrejditz can report back what he sees, so that I can then do another release that fixes it for him 🤪

[sbf-]

I literally can't find any documentation detailing all of the device classes

Here they are

8000=DevClss0\0\All Devices
8001=DevClss1\0\Solar Inverters
8002=DevClss2\0\Wind Turbine Inverter
8007=DevClss7\0\Battery Inverter
8008=DevClss8\0\Charging station
8009=DevClss9\0\Hybrid Inverter
8033=DevClss33\0\Load
8064=DevClss64\0\Sensor System in General
8065=DevClss65\0\Electricity meter
8066=DevClss66\0\Gas meter
8067=DevClss67\0\Generic meter
8096=DevClss96\0\Tracker
8128=DevClss128\0\Communication products

Except for 8009, there all coming from official SMA sources.
8009 was found by running SBFspot on a plant with a Hybrid Inverter

Done: d7ff8ef

Shipped in https://github.com/wimleers/homebridge-sma-home-manager/releases/tag/1.1.2 — @andrejditz , please update to this version and report back what you're seeing in the log. That will give us the answers we need 😊

[wimleers]

@sbf- HAH! I just shipped the logic that would have given me that same number. 😆 Well, let's hope that @andrejditz confirms it's 8009 then! 🤞

It's interesting that you even have charging station, gas meter, generic meter and so on in there. Where did you find those?! 😳

P.S.: are you the sbf of https://github.com/SBFspot/SBFspot? 😮 You really seem to be 😅 If so: pleasure to meet you, and quite the honor to have you contributing here! 😊
P.P.S.: I've actually been looking into stopping to use ModBus altogether and instead use Speedwire to read the data, that seems to be A) more reliable, B) more future-proof, C) how SMA devices actually exchange data between themselves. Unfortunately I've been unsuccessful at finding official documentation for this, and have only found partial implementations by others. If anybody is likely to know how to do this (or where to find docs for it), it's you, so … any chance you can point me in the right direction? 🤞
