Support for SUN-M80G3-EU-Q0

Hi, I'm running the Dummycloud with a Deye SUN-M80G3-EU-Q0 with Firmware MW3_16U_5406_2.32-D1 and I receive a lot of data packets that contain bullshit after being parsed. Most of the time, I receive multiple packets in row and often the first one contains reasonable data and the latter bullshit. But this is not always the case.

Here are some example logs:

Can you make any sense of it?

Oh interesting. I was wondering if it would work with the new SUN-Mxx inverters or if they've changed something about the protocol. Turns out it's the latter. I was kinda expecting it to be this was though after having seen the Deye SUN-12K packets and those being entirely different as well.

The data you're receiving isn't garbage. The parser just doesn't know how to make sense of it.

What is interesting is this:

LSW5BLE_MW17_5406_RELAY_270_1.00-SH

Is your SUN-M80 one with the NA relay integrated? Afaik there were some units that required the external SUN-MI-RELAY-01 and others that come with it inside it. If so, this kinda looks a bit like as if the internal relay module to the cloud still pretends to be an external one or something like that.

There are a few ToDos here.

First of all, you should check if the data is actually correct and not just plausible. For that, either compare with what you see in the solarman cloud or check what you can read via modbus.

Then, if the hypothesis is correct, someone unfortunately would have to use the solarman cloud and see if they can see any data from that relay module. If yes, they'd then have to sample the data there while also doing a package capture so that one can make sense of the package structure by comparing values in it with known data at a given point in time.

If the data you see in the first packets is actually correct and there's nothing relevant in the relay packets, it might be enough to figure out a way to detect that they are relay packets and discard them. Looking at the kaitai struct I wrote for the packets again, maybe it's as easy as this field being a 03? https://github.com/Hypfer/deye-microinverter-cloud-free/blob/e35914b2d1f08cc1431ccd628f65427f390acc90/assets/deye_sun600.ksy#L43-L44 Can't verify that with the string representation in the log you posted though

Thanks for your answer, @Hypher. It's a bit annyoing that I can only test it during the day. I hope, I can try something out soon.

The relay is external.

First of all, you should check if the data is actually correct and not just plausible. For that, either compare with what you see in the solarman cloud or check what you can read via modbus.

For me the content of the first packet looks quite correct.

The only difference is the total production, but here the one from dummycloud looks more reasonable.

The values also match with those in the web UI.

For debugging, I'd recommend adding some code here that either logs as hex or writes to a file so that you can share one of the packets that fail to parse properly https://github.com/Hypfer/deye-microinverter-cloud-free/blob/e35914b2d1f08cc1431ccd628f65427f390acc90/dummycloud/src/DummyCloud.js#L31

I'm sorry, it looks like I had removed that line by accident for the second packet in my first post. Here is one group of packets with HEX and JSON:

For me, the easiest way for now is to just discard those packets, that don't have a valid date, after parsing. But that might not be the proper solution that you have in mind...

Hm. Those data packets that get parsed correct-ish looking have what I called payload_magic in the kaitai struct set to 129 as opposee to the expected 1. Maybe that should be read as 0b10000001 and 0b00000001 respectively and that bit is a flag?

It looks like it's data from a prior point in time. But why would the inverter send that to the cloud?

Wild guess but maybe to combat that there are holes in their graphs if there was a short internet outage and therefore the logger now keeps n to n-10 packets and always sends them on each report interval?

Thanks a lot. Tomorrow, I'm not at home during the day. I'm gonna try it on Friday.

Please try b29b255

Looks good.

But, is it normal that the timestamps in inverter_meta.current_time doesn't correspond to the actual current time but to the time of the previous round?

If you take the first packet from the log you've posted

[2024-04-10T15:43:10.935Z] [TRACE] 2024-04-10T15:43:10.935Z Data 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

and decode that, you'll find that the date contained is 18 04 0a 0f 26 07 which is 24, 4, 10, 15, 38, 7 in decimal meaning 2024-04-10 15:38:07

So yeah, that's actually what the logger reports. I'd suspect that the timestamp is the start of the 5 minute sampling period over which the data is averaged.

Yes, I had no doubt that the parser is correct, I was just wondering if that's the normal behavior of these inverters.

Or the inverter has no internal wall clock at all and just stores and passes the last timestamp received from the cloud (which leads to the same effect in the end).

Sure that is possible, but what would be the point of doing that?

Of doing what? Having no internal wall clock or storing and passing the last timestamp?
