EPEVER Modbus RS-485 Config

Humm, stil nothing.

Im sure the port is 8088, i scan IP and the port is open, and im conected to the wifi box. I still can’t decode any data.

I dont know what to do more.

I get this in home assistant.

Pymodbus: epever: Modbus Error: [Input/Output] No Response received from the remote unit/Unable to decode response
08:47:17 – (ERRO) Modbus

I now disabled the MT50 and using only the Wifi Box. The home assistant message changed but still not recieving data.

Damn. Color me impressed. I’ve been using a Pi with a Python script to send the data over MQTT to my OpenHAB box. This would simplify it and free up a Pi for some other task.

I have same issue with modbus and eBox-TCP-02. No data received.

Works perfectly fine with AdamWelchUk nodered routine via mqqt.

How do you get the ip of the epever?

I have connected my epever charge controller to my HA RPI but don’t get any data with the below configuration.

Must I install any drivers? How do I find out which port my epever is using?

OMG, I got it to work using your settings. Unbelievable. Didn’t have to install any drivers on a clean RPI4 install. Thanks!!!

Hello,
Thank you very much for this post which helped me a lot!
Then I have a functional configuration, which I transmit to you below.
To begin I have an EPEVER XTRA3210N-XDS2.
I have then a machine for modbus with the software “mbusb”.

With a chinese cable and the “CH343” chip I have installed the driver:

I have configured as follows MBUSB

root@modbus:/etc/mbusd# cat mbusd-ttyCH343USB0.conf

#                                           #
#############################################

########## Serial port settings #############

# Serial port device name
device = /dev/ttyCH343USB0

# Serial port speed
speed = 115200

# Serial port mode
mode = 8n1

# RS-485 data direction control type (addc, rts, sysfs_0, sysfs_1)
trx_control = addc

# Sysfs file to use to control data direction
# trx_sysfile =

############# TCP port settings #############

# TCP server address to bind
address = 0.0.0.0

# TCP server port number
port = 502

# Maximum number of simultaneous TCP connections
maxconn = 32

# Connection timeout value in seconds
timeout = 60

######### Request/response settings #########

# Maximum number of request retries
retries = 3

# Pause between requests in milliseconds
pause = 100

# Response wait time in milliseconds
wait = 500

# Reply on Broadcast
replyonbroadcast = no

I then connected it in modbus to Home Assitant

I’m still trying to understand the difference between PV ARRAY LOW and HIGH, that’s why there are high values on the panel

So i have an EPEVER wifi 2.4g RJ45 A connected to my wifi but it doesnt connect to my home assistant i get the error: Connection to (192.168.178.187, 8088) failed: [Errno 111] Connection refused

If some one could help that would be much appreciated.

I just did a full port scan and not a single port was open was i wrong setting it up over the epever pair app?

Could this be that on these newer devices Epever want’s to use their cloud service and that’s why don’t open local ports?

I have UPower-HI series hybrid-inverter and hopefully I get “EPEVER-WIFI-2.4G-DB9-B” (this connects to DB9 connector) on next week and I can check if there is open ports to connect it to HA.

BTW, they ship newer USB cable with UPower-HI adn looks like it use CH343 chip nowadays.

Today I scanned open ports of my EPEVER-WIFI-2.4G-DB9-B and only port what was open was 65010/tcp. But when I connected WiFi dongle to Epever Cloud (with EPEVER Pair app) then all port was closed, actually whole SSID went missing.

So 65010/tcp is for EPEVER Pair in local mode, but no idea what kind of service/api is that…

Epever has changed registers for the UPower-Hi series from UPower. I found perl script from German FHEM forum https://forum.fhem.de/index.php?topic=111967.0 and downloaded it.

I don’t know perl but looks like there is new registers for UPower-Hi, like for PV, I assume this “i13641” is register for PV Array Voltage :thinking:

          "i13641" =>  {       'reading' => 'PVInputVolt',
								  'expr' => '$val=($val/100)." V"',
                       },
          "i13642" =>  {       'reading' => 'PVInputCurrent',
								  'expr' => '$val=($val/100)." A"',
                       },
          "i13643" =>  {       'reading' => 'PVInputPower',
								  'expr' => '$val=($val/100)." W"',
                                   'len' => '2',
                                'unpack' => 'l>', 							  
                       },
          "i13655" =>  {       'reading' => 'PVTotalCargePower',
								  'expr' => '$val=($val/100)." kWh"',
                                   'len' => '2',
                                'unpack' => 'l>', 							  
                       },

Any ideas how easy is to convert to python? Whole perl script can be found here.

What Type of Temp. Sensor does the Tracer-AN use?

hi @timnis, we are in the same boat…

I expected the ebox-wifi-01 to connect with the UPower-HI but I had a bad surprise as the RJ45 port is not meant for that. Some store told me it is possible to connect the ebox-wifi-01 on the RS485 with limitations, I tried to follow the RS485 interface pin scheme described on the UPower-HI manual and build an adapter but sadly it did not work.

I am not planning to buy “EPEVER-WIFI-2.4G-DB9-B" until I am 100% sure it will work with Home Assistant.

Epever is a very famous brand, it is hard to believe there is no integration built for Home Assistant.

Please keep me posted if you find a solution.

By the way, I found a new dongle on the official website “EPEVER WiFi Adapter 2.4G RJ45 C” no idea if this works with the UPower-HI, but I guess not :stuck_out_tongue_winking_eye:

hi @marcao88

Yes there is rs485 rj-45 port on UPpower Hi, but like I have it’s connected to BMS-LINK.

If you have ebox-wifi-01, make the cable and connect it to DB9 connector, should be easy and pinouts are in the manuals. That way you should able to connect like in this thread.

I have feel that Epever try to get all new inverters connected to their cloud services (like other manufactures also) and from there I assume in future they offer API (in Epever Cloud service, there is already some mentions on the API). That way it works in normal conditions. But if after few years cloud service stop working or you have unreliable/no internet connection then it is problematic.

I finally ditched “EPEVER-WIFI-2.4G-DB9-B" and I have old rpi2b connected via usb-rs485 cable to inverter (which was delivered with inverter). Basically config same as in post #67 by dylan, but with different registers values. This has been worked for me few weeks now without problems and I also control from HA when UPower Hi charge battery from grid (and when consuming it).

Check this for newer register values https://community.home-assistant.io/t/epever-upower-hi-modbus-setting-if-you-need/483184. And from this perl script you will find more register values (from German FHEM forum)

Please forgive me for asking for help but I could not manage to get it done and you are my last hope.
I made the cable but it did not work, my ebox-wifi-01 remains dead. :sob:
This is what I prepared:

I am using this adapter:
adapter2

And having this cable order, that is not working:
adapter3

This is what I found on the official manual:
I am not sure what to do with pin 1,2 and 6. Even 4 and 5 are confusing to me as in the adapter it had a GND door that I am not using.

The link below refers to the ebox wifi manual, that contains more fancy Definitions for the pins…

Thank you for your support. :slight_smile:

cal wifi connectivity adapter

Hi,

Ebox-wifi-01 works on 5vdc and below is Pinout from UPower (older version) RS485 port.

So, I assume you need to connect following pins

Rj45 - db9
1 - 9 (5vdc)
7 - 5 (gnd)
5 - 7 (A)
3 - 8 (B)

Thank you! It was very helpful, for me to understand it, but this is what worked por the UPOWER HI RTU, I hope more people will benefit from this finding:

RJ45 - DB9
1-9 (5V)
3-8 (B-)
5-7 (A+)
7-4 (gnd)
8-5 (gnd)

Good. According pinouts there is two GND’s, but maybe only one is connected.

Anyway, nicely done :+1:
