⚡ Solarman Stick Logger by David Rapan

Wait… what? How can I possible check that?

davidrapan · March 20, 2025, 9:39am

Hi @Mathieu7, disconnecting in HA doesn’t really say anything about the connection itself. It will also disconnect when there is an error, etc.

davidrapan · March 20, 2025, 9:43am

You’ll probably have to take a chance and possibly return it.

Just want to mention that I managed to get the David’s version of solarman stick logger working on my ESI series Sofar Hybrid Inverter.

Bluesun BSE12KH3: Function code 131 instead of 3

bug

### Description Hey @davidrapan, I'm not sure if I should turn to pysolarmanv5… project in this case, but since I'm using this integration, I'll try here first. I have a Bluesun BSE12KH3 inverter paired with a Solarman's LSW5-BLE stick logger. I have been trying to wrap my head around this whole process for a couple of days now, starting from a complete newb standpoint. Following your guide/understanding to some extent how pysolarmanv5 works, I tried to follow the steps using the afore_hybrid.yaml as recommended. The local IP is correct (have no problem accessing it through web) as well as the serial number. No matter whan I did, I was always unable to setup any devices/entities, the integration just keeps trying to reload with a "function code 131 instead of 3". ![Image](https://github.com/user-attachments/assets/b4639408-3717-409d-84d3-3e5761983634) ### Reproduction Steps What I then did is try the register scan with a following example for "PV1 Voltage" register and this was the result: When decoding the received frames (using pysolarmanv5's decoder from utils), I mostly get a failed CRC and the data always comes out to be the same. (0500 or 018302c0f1). Occassionally I manage to get function code 131 decoded as well, but it didn't happen in this two examples. **EDIT** (Function code: 131 while decoding a holding register response): Is this related? ![Image](https://github.com/user-attachments/assets/9e648d7d-8832-4e46-931e-972cd0669815) If I understand correctly, should "Data" be the requested value in this case? ### Log ``` Scanning input registers DEBUG:pysolarmanv5.pysolarmanv5:[353xxxxxxx] SENT: a5 17 00 10 45 8f 00 xx xx xx d2 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 04 02 2b 00 01 40 7a b1 15 DEBUG:pysolarmanv5.pysolarmanv5:[353xxxxxxx] RECD: a5 10 00 10 15 8f 76 xx xx xx d2 02 01 a1 5e 5b 32 82 1a 00 00 5f 3d 6e 35 05 00 70 15 Finished scanning input registers Scanning holding registers DEBUG:pysolarmanv5.pysolarmanv5:[353xxxxxxx] SENT: a5 17 00 10 45 90 00 xx xx xx d2 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 03 02 2b 00 01 f5 ba a6 15 DEBUG:pysolarmanv5.pysolarmanv5:[353xxxxxxx] RECD: a5 13 00 10 15 90 77 xx xx xx d2 02 01 a1 5e 5b 32 82 1a 00 00 5f 3d 6e 35 01 83 02 c0 f1 a7 15 Finished scanning holding registers ``` ### Version 25.02.14 ### Home Assistant Core Version 2025.3.0 ### Home Assistant Operating System Version 14.2

Dear David,

Although I am not having my hands on my HA green yet, I am preparing to get my Deye SUN12 integrated in HA and of course your library seems the best match, especially as I do have an LSE-3 logger
As I have the current problem that the LSE is NOT delivering battery information (number of connected batteries, serial numbers etc.) into Deye cloud (which is just insane imho, because the LSW-3 is delivering this information to the cloudservice) I wanted to ask the following: does for your integration the LSE-3 (Ethernet logger) read and provide battery information for HA? Best, Seb

angusc · April 2, 2025, 6:19am

Hi guys,

Firstly thank you to @davidrapan for this great integration, i have been using it for long time perfectly with my SP3000 Inverter. But for the last few days it has stopped working and all sensors are not available. This morning i tried to delete the Inverter and then restarted HA and re installed the integration, but still not working. Is it anything to do with the clock time change on Sunday night…?

davidrapan · April 2, 2025, 5:18pm

does for your integration the LSE-3 (Ethernet logger) read and provide battery information for HA?

Hi @lucullus, yes it should work w/ Ethernet Logger too.

davidrapan · April 2, 2025, 5:24pm

Is it anything to do with the clock time change on Sunday night…?

Hi @angusc, I don’t think it’s related. First, try to make sure that the HA is still able to establish a connection to the inverter IP, for example using the ping command. And what does the debug log show?

angusc · April 2, 2025, 5:54pm

Ping is good to the connector. But i notice the Solarman app is not getting data either. The connector is online but the Inverter shows off line.

davidrapan · April 3, 2025, 7:56pm

And what does the debug log show?

Francesco78 · April 3, 2025, 11:26pm

Good evening David,
I installed a new machine with home assistant and your integration a couple of days ago. The version of home assistant is 2025.4.0 and the version of your integration is 25.03.18.
Every thirty minutes the Logger disconnects from the wifi and I have to turn off home assistant for a minute to reconnect the logger to the wifi. I tried not to turn off home assistant for an hour and it does not connect. the configuration is deye_hybryd.yaml

What could it be?
I set update_interval to 15 in the yaml file in all the values that were 5.

With the other integration of Stefhan it has worked since December 2024, but yours is much further ahead.

Twin_Decks · April 4, 2025, 1:08pm

Hello, I’m excited to get this going ( I want to heat my pool when battery is charged…) but I’m having a bit of difficulty understanding what to do with an error on initialisation. I’d be very grateful for any suggestions.

I have. Sofar ME3000sp with WiFi stick. My serial number is 806789129, so I’m not sure if this means V4. I don’t know of any firmware upgrades…

Here is my error code and logs.

Restart Home Assistant and start log debug for send link txt.

lucullus · April 16, 2025, 10:46am

Hey,

first of all: thx to @David Rapan for your work! Installed like a charm on my HA green and everythign went well with the inverter SN. However, after 4 days I had not data from the Deye anymore in the Dashboard → error msg that the wrong SN is inserted and that the inserted (inverter) SN does not correspond with the SN the system gets. Then I had to change the SN from the inverter SN to the logger (LSW3) SN and since then it is working again.
Nonetheless I wonder how this change could happen? Any explanation for it? Best, S.

Francesco78 · April 16, 2025, 5:43pm

The sensor: inverter_dc_temperature every day worn data ( -100°)

I have solution for this problem ?

hi, i have a 20kw zcs hybrid inverter pair with 20kw/h weco battery. I was wondering if with this integration is possible to control the charde and discharge time based on electricity tariff, also if is possible to set the battery discharge %.
The zcs inverter should be a rebrand of sofar inverter and i am using a classic solarman wifi stick.
Thanks for the fantastic work!

Hi. In the integration there are only sensor entities, is it possible to make some activations via the remote control option?

I am trying to automate the prosses by disabling or enabling solar sell and or changing the system work mode from “zero export to CT’ and Selling first, is it possible

Of possible I would like to use all fictions in. Remote control
