If I can provide more info, I'd be happy to help. Awesome project!

[heeplr]

I briefly looked at the data and found battery charge percent (byte offset 35) and battery temperature (73).
I will try to find the remaining values in the next days.

If you are interested, I'd prepare a PR to support the differing message structure.

Is it obvious from the dump, how we could differ the different protocol versions/device models other than the name string?

[heeplr]

I've roughly adapted my fork to work with Solarbank Pro 2 devices (maybe other Solarbanks, too).
It's in rough state but works-for-me (tm).

Leaving this up for folks from search engines. Please feel free to close.

EDIT: link fork

thanks for this fork. Would you say it works good? Any changes so far? I want to try and integrate into Homeassistant.

P.s.: Unknown1 should be the Light Led on/off from the solix?

yes, it works reliably to monitor but there's room for a lot more reverse engineering.

P.s.: Unknown1 should be the Light Led on/off from the solix?

I'm not sure. I didn't touch the LED setting and "unknown1" goes from 0 to 1 and 2 during the day. If I had to guess i'd say it's

• "battery discharging" = 1 (battery_power < 0)
• "battery unused" = 0 (battery_power == 0) and
• "battery charging" = 2 (battery_power > 0)

(but I'm not sure)

If you find out, it'd be awesome if you could share your findings here or over there (just enabled issues there).

[LeagueRaINi]

is there any discord thats putting an effort into reversing this? the structure of the messages seems simple but i'd need more logs of different devices or dump the firmware to continue in any meaningful way

here is how the messages seem to be structured:

FF 09    | message prefix
XX XX    | message length (including prefix)
XX XX XX | same across all messages i receive (`03 01 0f`)
XX XX    | `84 05` on my telemetry packets and `04 09` on the other i haven't figured out yet
XX       | seems to increment on my telemetry ones 13, 23, 33, it's just a1 on said other message ^

then we get to the data

XX     | data type (A1, A2, A3 ...)
XX     | data length
XX ... | data
  - first byte in the data (if the data length is above 2) seems to indicate what value type the data is

here are some examples

A2 | SolarBank Serial
11 | Data length
00 | Unk // 00 = string?
XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX | Serial string

A3 | Solarbank Battery Percentage
02 | Data length
01 | Unk // 01 = u8?
64 | Percentage

AA | Solarbank Temperature
02 | Data length
01 | Unk // 01 = u8?
1d | Temperature

C0 | Smart Meter Serial
11 | Length
00 | Unk // 00 = string?
XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX | Serial string

in my case the telemetry is so big its send over 3 messages and is over 500 bytes long, there is A LOT of data in there, going to try and get more types figured out when the sun is out and i'm actually producing something

// hope what i info dumped here makes at least a bit of sense its quite late here ^^

i mostly figured out how the telemetry packets work but my its semi useless to me cause connecting to my solarbank via bluetooth messes up the connection to ankers services and breaks the app till i manually reconnect it so for me there is no point in spending more time on this but i shouldve posted more than enough info for anyone with a bit of experience to work with and write a proper framework

[thomluther]

i mostly figured out how the telemetry packets work but my its semi useless to me cause connecting to my solarbank via bluetooth messes up the connection to ankers services and breaks the app till i manually reconnect it

So you are saying that the BT interface cannot be used in parallel from a BT client and the App?
Then it probably does not make much sense to invest too much time into it unless there is no other interface for the device.
The difficulties I see in the BT interface:

• Connection Range
• Each device type need to be reverse engineered by an owner who has local BT access to the device
• No parallel usage with the App as you mentioned

I recognized the same. WiFi disconnects when Bluetooth is enabled. Afterwards, the app shows the Solarbank as offline. I think this can be solved once the command for properly disconnecting is reverse engineered as the app usage doesn’t react like this. E.g. if you are going out of range with the anker app via Bluetooth connected, then the anker is not showing as offline and messing up the connection.

Maybe there is a command to set the solix also in parallel mode?

[mboisson]

I mean, if we can get all of the information and commands through BT directly into HA, then who cares about the Anker app ? I would much rather have the information in HA than in Anker. It is still worth it in my opinion, and I can contribute and test, but I know very little about BT protocol and the code base.

[sd8rdb]

Well. Looking to the data which comes via Bluetooth, it much less which is in the cloud. As an example, there is no info about what is coming from PV1 to PV4.

That's all in there this project and the forks just don't collect the complete blob

And that is the big pain with the BT interface. You need very detailed reverse engineering by experts willing to debug hex data and compare them with their device values in parallel to get an idea of what they mean. This is just for monitoring...
And for each device type or new device generations that add new features, the process must be redone by experts owning such a device...
This is not trivial, since it is already complicated through the cloud Rest Api, which may deliver just state codes for various conditions that just Anker knows how they have to be interpreted...
Decoding such state codes from hex values will not give you any clue what the byte stands for, or if it is just a significant part of a larger value.

figuring out correlations between data isn't rly something that requires expert knowledge of reverse engineering and if parsed properly this should work on almost every anker device but that's not what this project does hence why it's only working for a small subset of devices and may break with new firmware update

[heeplr]

And that is the big pain with the BT interface. You need very detailed reverse engineering by experts willing to debug hex data [...]

That's pretty much the case for monitoring aswell (and I guess also for WIFI?)
It can be done by

And for each device type or new device generations that add new features, the process must be redone by experts owning such a device...

Owners could just dump data + screenshot the app and upload it to experts who reverse engineer it.

This is not trivial, since it is already complicated through the cloud Rest Api,

The downside here is (i guess the reason for this very project), that you need a working internet connection.
