Support for Ethernet Logger LSE-3

[oetiker]

I am using a Sofar Hybrid Box (SOFAR HYD 20KTL-3PH) with a LSE-3 logger and get no responses when trying to use the thing with the ha-solarman code. Neither with the code here nor with the original from StephanJoubert.

Reading through @StephanJouberts repo I found this issue which seems to indicate that the LSE-3 device needs different encapsulation ...

Anyone working on this ? Or is there some secret to get my setup to communicate with ha-solarman which I just neglected until now?

[davidrapan]

Hi @oetiker!

I can try to implement suggested changes but as I don't have the device it will be like shooting in the dark.

Are you willing to try it afterwards and help solve potential bugs and so?

Have fun!

Hi David

yes sure, I would be totally willing to test and help out :)

cheers tobi

[davidrapan]

Ok, I'll let you know whenever there is anything to try out.

But as the code of those suggested changes is apart from the pysolarmanv5 it won't be as straight forward implementation as I initially thought so I can't make promises it will work as great as when it goes through the mentioned python library. But I'll do what I can to make it work. 😉

Have fun!

[davidrapan]

Does the Ethernet Stick Logger also responds to the discovery packet? Probably not, right?

[Vollpanto]

I have both sticks. The Ethernet Adapter also response to the discovery packet.

[lcavalli]

Indeed it seems so. I currently use an integration based on pure modbus protocol, but I'm testing your integration and the config flow correctly presents the logger IP address, port and also serial number.

[davidrapan]

Okay, thanks guys. I'm currently investigating possible approaches to the implementation.

[davidrapan]

Guys, can anyone test feat: Experimental testing of ethernet stick and show me the debug log? Thanks!

For enabling this there is a new configuration toggle (Solarman protocol passthrough mode) which must be in on position.

[lcavalli]

@davidrapan, It is not lack of interest, I'm currently not at home. I will be able to test it when I will come back! Thank you for spending time on this issue.

[davidrapan]

And then for anyone who is going to try it there is this row in the api.py file (on line 34):

modbus_frame = v5_frame[10:]

Try to tweak number 10. It says how much it should cut from the response from the start and treat the rest as an modbus frame. So try for example maybe also 20 and 2...

But it really depends on what the code is gonna do.

[oetiker]

@davidrapan I will be glad to test, but I have not read the code to deeply and I am involved in way to many projects atm ...

• how do I get the current version of the code ? can I just update ?

• do I just toggle the new config setting in the config screen ?

[davidrapan]

Hi @oetiker,

how do I get the current version of the code ? can I just update ?

You would have to manually download the code in zip and replace it in the HA as this changes are not part of any release.

do I just toggle the new config setting in the config screen ?

Yes.

[lcavalli]

how do I get the current version of the code ? can I just update ?

You would have to manually download the code in zip and replace it in the HA as this changes are not part of any release.

You can also select master in version combo box in HACS. Download again if already installed.

[davidrapan]

You can also select master in version combo box in HACS. Download again if already installed.

I know that you "can" do that but it won't switch to it. It reselects automatically to the release version and thus it never worked for me.

And I think it was also stated that they gonna remove that feature all together though.

[davidrapan]

It's now part of the 24.08.08 pre-release.

[davidrapan]

I was hoping someone would at least give it a try before the planned 08/14/24 release, but I guess I'm out of luck, huh? 😆

[lcavalli]

@davidrapan I'm not at home! Will try as soon as I will be back for sure.

[davidrapan]

@lcavalli, I know you said that! 😆 I did not mean to pressure anyone with that post! 😆

[proggaras]

Great work. Will this also work, when I connect directly to my Deye inverter over RS485?

Detail: HomeAssistant connects over a "Waveshare RS485 to Ethernet Converter" to my Deye SUN-25K-SG01HP3-EU-AM

[davidrapan]

Hi @proggaras, this is what https://github.com/kellerza/sunsynk or modbus tcp is for, I guess. 😉

This integration specializes on using Solarman protocol only.

@davidrapan yey, I finally got to test ... unfortunately it does not work yet,. but there is debug data. this is with the released version .17

[davidrapan]

Hey @githubDante, can you take a look at our experiment?

Edit: Nevermind I maybe got it, will see... 😆

[lcavalli]

Back at home. I tried the new feature and as already reported it doesn't still work. The reported error is the same as already logged above (crc error). To further analyse the issue I installed tcpdump on Home Assistant Operating System and dumped a session from a different integration based on bare modbus (I would like to replace due to some inconsistencies in reported values). This is the starting working request to read the serial number on ZCS Azzurro inverter (addess 0x0445, length 7). Request:

Reply (obfuscated):

CRC seems not to be used as part of the protocol, since it is modbus TCP, not RTU.

[davidrapan]

Oh I didn't know that tcp does not have the crc, my bad.

But i mean the response is there so if we just cut it like this [6:] and add crc that it has to work.... 😆

Edit: I just tried it and it did worked! 😆

[davidrapan]

Guys try it from this commits: feat: Experimental testing of ethernet stick + fix: Experimental testing of ethernet stick typo

[githubDante]

Hi,

@lcavalli do you have the pcap file from tcpdump ?

@davidrapan if the ethernet logger operates in MODBUS TCP mode you can use a shortcut by passing a prepared request directly to the _send_receive_v5_frame function and await the result from it. The following is a simple example

from umodbus.client.tcp import parse_response_adu, read_holding_registers, read_input_registers, read_discrete_inputs, etc.   # you can map these to function codes should you wish 
...
tcp_req = read_holding_registers(<slave id>, <starting address>, <quantity>)  # choose the appropriate function 
# feed the tcp_req directly to _send_receive_v5_frame and process the result as follows ...
resp_adu = await super()._send_receive_v5_frame(tcp_req)
inverter_data = parse_response_adu(resp_adu, tcp_req)
# no other intervention should be needed the data can be returned directly 

• An example with data provided by @lcavalli (with slightly modified Transaction identifier)

>>> req = read_holding_registers(1, 0x0445, 7)
>>> req
b',\x9a\x00\x00\x00\x06\x01\x03\x04E\x00\x07'
>>> req.hex()
'2c9a00000006010304450007'
>>> resp_b = bytes.fromhex('2c 9a 00 00 00 11 01 03 0e 5a 4d 32 45 53 30 30 30 30 30 30 30 30 30')
>>> resp = parse_response_adu(resp_b, req)
>>> resp
[23117, 12869, 21296, 12336, 12336, 12336, 12336]
>>> b''.join([struct.pack('>H', x) for x in resp])
b'ZM2ES000000000'

[lcavalli]

It works now! Experienced a short disconnection but sensors are now available. Thanks!

@githubDante yes, I have a pcap dump but it contains sensitive data, I suppose, like the serial number of the inverter used for solarman cloud registration.

[davidrapan]

It works now! Experienced a short disconnection but sensors are now available. Thanks!

😆 😆 😆

I'm literally laughing my ass off! 😆 But I'm glad it worked!

Can you enable debug and do some logging for me?

@githubDante Thanks for your fast reply! You da best! But turns out umodbus.client.tcp is not really needed and pysolarmanv5 (+ really small tweak) is capable of reading the data. 🎉 But I'll try it both ways, though.

[davidrapan]

I wonder if is the start of the reply a5 17 00 10 45 the same every single time? So it can be used to detect it's the ethernet stick logger, hm.

[davidrapan]

Great! Can you also test it with changes made here?: feat: Add some constraints for ethernet sticks

Can you guys believe it that adding support for those sticks only needed around 16 rows of code? 😆

[PV-Joe]

I was watching the development and think you are doing a great job here. Glad to see that Solarman is getting some love and is being continued. ☀️

[lcavalli]

I would like to test your last commit but after a series of periodic disconnection this night the inverted become offline and I cannot connect anymore.

The inverter is offline also on the official app.

Is is possible that the query rate was too high? Will try to reset the unit.

[davidrapan]

It should not be possible to shut it down like that though. But you can increase it in the definition profile with update_interval.

Please could you try to catch in debug log why it disconnects periodically? 😉

[oetiker]

I copied with the api.py from main and yey it does work ... it does seem that not all queries succeed though ... I guess some timeouts are not yet as they should be

[davidrapan]

Well for me to even have a chance to do something about it I'm gonna need to see the debug logs, haha. 😆

And you tried it also with the last commit?

[oetiker]

Well for me to even have a chance to do something about it I'm gonna need to see the debug logs, haha. 😆

And you tried it also with the last commit?

yes with the version from 9h ago ... will investigate the timeouts

[davidrapan]

What profiles are you using guys anyway?

It should not be possible to shut it down like that though. But you can increase it in the definition profile with update_interval.

Please could you try to catch in debug log why it disconnects periodically? 😉

Inverter still offline with the integration disabled. As soon as it will be online again I will try to investigate the disconnection issue. Good to know that the rate can be configured in definition file.

sofar_tlx-g3.yaml (wr) and sofar_g3hyd.yaml (hwr)

the connectivity problems seem to have 'system' ...

[davidrapan]

Enable debug logging and try to catch that disconnect. 😉

Anyway the wireless version can be bombarded even every second and it works great and I would thought that ethernet one should be even better in that regard but who knows maybe not.

[lcavalli]

What profiles are you using guys anyway?

I'm using this profile, although my inverter is single phase only: zcs_azzurro-hyd-zss-hp.yaml

BTW, the logger is still unable to communicate with the inverter (LAN led is on, COM led is off, SER led is blinking@1hz). Now I disconnected the logger from the inverter, will reconnect tomorrow.

I really hope everything will be alright in there! Even to say I find it hard to believe that simple data requesting (more so when the device was talking with us successfully) could somehow break anything... Well that being said I still hope it really did not, huh!

What 'bout you @oetiker, everything good?

[davidrapan]

Can you guys also try this version?: feat: Ethernet Logger through umodbus.client.tcp

Link to api.py: https://github.com/davidrapan/ha-solarman/blob/dev/custom_components/solarman/api.py

It's according @githubDante suggestions.

Don't forget to also produce debug log and post it here so we can look. 😉

Edit: Also added little upgrade: feat: Add register writing for Ethernet Logger

Hi, inverter is back online. I'm checking the disconnection problem, this is the log portion of interest:

I modified the inverter profile to query every 20 seconds. At the beginning everything is working, until 15:32:33.815, when the data logger stops answering. After 5 attempts the integration aborts and close the connection. After several retries the data logger restart its normal behavior and replies are correctly processed. I don't know if it is a sort of protection of the data logger with respect the query rate (now 20 seconds, but 7 independent queries are performed together in sequence).

Edit: The cycle of the disconnection is every 15 minutes.

[davidrapan]

Yeah well it could be really anything... but as I already stated I would guess that the ethernet version could be little bit more resilient that the wireless. :-/

Anyway try it with the changes I was talking one post above. It could change this for the better. (If it will work though as I can't be sure if I did not forget anything I'm just blind guessing cause I don't have the device) 😉

Edit: The cycle of the disconnection is every 15 minutes.

Really strange. Can you see also any changes in the regular behavior with the same period?

[lcavalli]

Anyway try it with the changes I was talking one post above. It could change this to the better. (If it will work though as I can't be sure if I did not forget anything I'm just blind guessing cause I don't have the device) 😉

Could you please make a pre-release? The update is easier with HACS 2.0 (cannot download master anymore).

[davidrapan]

Haha the changes are in different branch.. I mean you can just swap the content of the api.py. I also gave you there link to the file.

I mean I could try to do that pre-releas but I think ^^ will be bit faster. :-P

[lcavalli]

Yep, will do manually, no problem. dev branch?

[davidrapan]

Yes. https://github.com/davidrapan/ha-solarman/blob/dev/custom_components/solarman/api.py
