Communication issue SUNSYNK-12K-SG04LP3 using Waveshare RS485 to PoE (B)

Open jeybee74 opened this issue 10 months ago • 15 comments

Hi, Thanks for a great integration 💯 ! I installed it yesterday and made it work using the same settings as shown in the Getting Started - Adapers & Wiring section for the SS 25k HV inverter.

When I moved the Waveshare POE device over to a permanent position I noticed that the data was not read every 5sek as I was expecting and now I feel I have tried everything. I now think that I probably had communication issues all along.

I have tried both serial-tcp with waveshare protocol set to none, and tcp with waveshare device protocol set to Modbus TCP-RTU. With excact same results. I have also tried 3 cables for RS485 and 2 LAN cables + tried without PoE and local power to waveshare device.

Does anyone else had same issues with this Waveshare RS485 to PoE (B) device, and found a fix?

RS485 is connected using the red cat6 cable

jeybee74 avatar Mar 02 '25 13:03 jeybee74

You have to use the same port as the battery. Not the ModeBUS port. You will need a splitter, see the guide on how to make one. Note that this is NOT just an ethernet splitter.

More infos about this splitter can be found here: https://solar-assistant.io/help/deye/2_in_1_bms_port

Thank you for the suggestion :) to connect to the BMS port,

However, I get the same issue, with the connection to the BMS port, pinout is the same, pin 1-3 for RS485.

Looks like the splitter only needs to be used on smaller inverters that is missing this ModeBUS port?

jeybee74 avatar Mar 10 '25 13:03 jeybee74

Not 100% sure, but as I understand this splitter is just used for those models that have this CAN and RS485 port combined.

proggaras avatar Mar 10 '25 15:03 proggaras

Not 100% sure, but as I understand this splitter is just used for those models that have this CAN and RS485 port combined.

I did not recieve any data when I tried the BMS port. So I guess I am using the correct port. Some wrong setting somewhere is probably the issue I guess..

So either you unplugged the RS485 cable after the addon started up, or the waveshare acts up in some way.

You could try:

  • adding only 1/2 sensors (no groups!!)
  • making the schedules muuuuuch less aggressive. See the solarman example in the docs as guidance.

Once either of the above is working, gradually increase things (more sensors, more frequent reads) until it is working as you expect.

If it's a device issue, you can also try playing with these settings: (but almost doubt it will make a difference, since that first read of all sensors was ok)

Thanks Johann,

I have tried updating the Waveshare rs485 to poe device to the latest firmware, still no improvements, I mean the integration is ok, I get data but still a lot of timeouts, seems to be about 3600 in a 24h period.

I have tried quite a few settings both for READ_ALLOW_GAP and READ_SENSORS_BATCH_SIZE, but it is the same issue with timeouts. I have also tried READ every 30seconds, still the same.

I just testet to read all sensors to see if it was any difference, here are the new log: ... | | battery_equalization_days, inverter_l3_voltage, battery_restart_voltage, | | | day_gen_energy, prog6_charge, inverter_l3_current, beep, prog5_capacity, | | | generator_max_operating_time, grid_peak_shaving, total_grid_export, drm4_code, | | | grid_give_power_to_relay_status, prog_wednesday_enabled, inverter_frequency, | | | drm6_code, grid_peak_shaving_power, battery_float_voltage, drm7_code, | | | prog3_mode, pv2_voltage | +-----+----------------------------------------------------------------------------------+ 16:49:16 WARNING us_version_grounding_fault: Unknown register value 0 16:49:16 WARNING allow_remote: Unknown register value 0 16:49:18 WARNING us_version_grounding_fault: Unknown register value 0 16:49:18 WARNING allow_remote: Unknown register value 0 16:49:27 WARNING us_version_grounding_fault: Unknown register value 0 16:49:27 WARNING allow_remote: Unknown register value 0 16:49:47 WARNING us_version_grounding_fault: Unknown register value 0 16:49:47 WARNING allow_remote: Unknown register value 0 16:50:26 WARNING us_version_grounding_fault: Unknown register value 0 16:50:26 WARNING allow_remote: Unknown register value 0 16:50:26 ERROR OSError in callback read_ss12k: timeout reading 1 registers from 544; timeout reading 1 registers from 552 poll_need_to_read Traceback (most recent call last): File "/usr/local/lib/python3.12/site-packages/ha_addon_sunsynk_multi/timer_callback.py", line 81, in wrap_callback await cb_call File "/usr/local/lib/python3.12/site-packages/ha_addon_sunsynk_multi/sensor_callback.py", line 110, in callback_sensor await ist.read_sensors( File "/usr/local/lib/python3.12/site-packages/ha_addon_sunsynk_multi/a_inverter.py", line 55, in read_sensors await self.inv.read_sensors(sensors) File "/usr/local/lib/python3.12/site-packages/sunsynk/sunsynk.py", line 134, in read_sensors raise IOError("; ".join(errs)) OSError: timeout reading 1 registers from 544; timeout reading 1 registers from 552 poll_need_to_read 16:50:37 WARNING us_version_grounding_fault: Unknown register value 0 16:50:37 WARNING allow_remote: Unknown register value 0 16:50:48 WARNING us_version_grounding_fault: Unknown register value 0 16:50:48 WARNING allow_remote: Unknown register value 0 16:50:56 WARNING us_version_grounding_fault: Unknown register value 0 16:50:56 WARNING allow_remote: Unknown register value 0 16:50:58 WARNING us_version_grounding_fault: Unknown register value 0 16:50:58 WARNING allow_remote: Unknown register value 0 16:51:07 WARNING us_version_grounding_fault: Unknown register value 0 16:51:07 WARNING allow_remote: Unknown register value 0 16:51:18 WARNING us_version_grounding_fault: Unknown register value 0 16:51:18 WARNING allow_remote: Unknown register value 0 16:51:26 WARNING us_version_grounding_fault: Unknown register value 0 16:51:26 WARNING allow_remote: Unknown register value 0 16:51:28 WARNING us_version_grounding_fault: Unknown register value 0 16:51:28 WARNING allow_remote: Unknown register value 0 16:51:37 WARNING us_version_grounding_fault: Unknown register value 0 16:51:37 WARNING allow_remote: Unknown register value 0 16:51:45 WARNING us_version_grounding_fault: Unknown register value 0 16:51:45 WARNING allow_remote: Unknown register value 0 16:51:47 WARNING us_version_grounding_fault: Unknown register value 0 16:51:47 WARNING allow_remote: Unknown register value 0 16:51:57 WARNING us_version_grounding_fault: Unknown register value 0 16:51:57 WARNING allow_remote: Unknown register value 0 16:52:05 WARNING us_version_grounding_fault: Unknown register value 0 16:52:05 WARNING allow_remote: Unknown register value 0 16:52:07 WARNING us_version_grounding_fault: Unknown register value 0 16:52:07 WARNING allow_remote: Unknown register value 0

Does this make any sence?

I could ask for a firmware update for the Sunsynk inverter also, but I don't know if that have been a problem in the past..?

I have ordered a new waveshare device, version (C) from another supplier along with a couple of rs485 to USB, so I will test some more in a week or two. I will post my results here when I hopefully get this fixed :)

Hi guys,

Here is an update of my timeout issues!

I have now bought a Waveshare USB-to-RS485 device and tested it, all timeout issues are gone (at least for the first 45min of testing). Seems ok now! I use this config:

Image

I have tried these 3: Waveshare RS485 TO ETH (B) Waveshare RS485 TO POE ETH (B) Waveshare RS485 TO ETH (C) and I get the same timeout issues on all of them.. I'll try to test with just a few devices on my LAN as well just to be sure.

jeybee74 avatar Apr 01 '25 15:04 jeybee74

I made my own Wifi/LAN RS485 gateway device from an ESP32 with LAB and an RS485 breakout module.

https://github.com/kellerza/sunsynk/discussions/324#discussion-7043693

It has been running pretty reliably since August last year.

How often do you collect data, and is your entities updated consistently?

I have now run the waveshare USB-rs485 adapter since last night with READ_EVERY: 5. sometimes the entity is updated every 5sek-ish and sometimes longer, it is not consistent, often it can be over 20, and sometimes 38sek+ for a entity to update. I think the issue with the waveshare ethernet device is just that this type of delay in data is shown as timeout and that it also happens on the USB device but then it is not reported as a timeout..

I am not sure, but maybe a firmware update on the inverter could fix this, or maybe all users experience the same issue but doesn't notice it..?

I also see that the data from the CT is often reported all over the place, like you see in this picture

I am basically not using any electricity from the grid at the moment as there is still plenty of sunlight. So I have set the system up to disable charging or use from the grid when batteries are above 45%.

thanks for your comment.

I have now tried 7, yes SEVEN different USB-RS485 devices. ALL works fine with no timeout issues :) So I guess the cabling from the inverter is fine ;)

I have also tried 3 different Waveshare RS485-ethernet devices; (B), Poe (B) and (C), with different settings, same issue with timeouts on all. But they all work fine and data is coming in to the entities just as good as with the USB-RS485 devices 👍

BUT also with the USB device the data is not updated consistently every 5sek as it should 👎 , sometimes the entities is updated every 5 sek, but sometimes the data is 28sek, or more before the entity is updated (sometimes 1m+), there is no timeouts while this happends via the USB-RS485 devices.

I am beginning to think that the "timeout" issues or whatever is always there, but that it is visible in the logs only when I use the Ethernet devices due to the different communication methods, if this makes sense...?

jeybee74 avatar Apr 08 '25 11:04 jeybee74

Here is an update of my trials with the Waveshare ETH devices.

I have tried a lot of settings and I have found out that this is the settings that works best for me:

Image Marked out the RS485-ETH adapter spesific settings.

remember to set the IP and port to the Waveshare ETH device.

This gives me still a lot of timeouts, but all data is correct in the entities.

jeybee74 avatar May 06 '25 07:05 jeybee74

Issues with timeouts was fixed in the latest update. The integration now shows 0 timeouts with my Waveshare ETH RS-485 device since I updated to edge/dev version 3d60254.

👍👍
