No data from EPEVER

[kalle3510]

Does the EPEVER MPPT XTRA4415N also work with your solution?
Errorcode 2 time flash, no data from EPEVER.
When I look with the oszilloscope, data reaches Wemos.
Unfortunately I am not familiar, how the data should look like. :-(

[softwarecrash]

Have you checked the epever have ID 1?

[kalle3510]

Can you please provide fotos of your wiring?

[kalle3510]

Of course, thanks for your request.

[softwarecrash]

thank you, can you post the esp-ip/livejson data please

[kalle3510]

I am at the end of my knowledge?
Perhaps you may help me how to post the esp-ip/livejson data.
You are not talking about the WebSerial information, see picture.

[softwarecrash]

Just Type in your Browser http://your.esp.ip/livejson

[kalle3510]

I did, and that was all what is shown on the screen
{"DEVICE_NAME":"EPEver2MQTT"}

[kalle3510]

Today I added a 850mA 5V power supply and removed the two supply wires from EPEVER. Unfortunately no change.

[softwarecrash]

ah i think i found it, the epever have a bit different modbus or register adresses. we need the actual datasheet for it

[kalle3510]

is this part of the user manual?
EPEVER Laderegler XTRA4415N-SMS-EL-V1.3.pdf

[softwarecrash]

no, it looks like this
https://github.com/softwarecrash/EPEver2MQTT/blob/main/Protocol/ControllerProtocolV2.3.pdf

[kalle3510]

I will contact the epever support

[kalle3510]

I found this one online: https://github.com/B48D81EFCC/esphome-epever-xtra-n-series

[kalle3510]

I received an answer from EPEVER, does this help?
A or BSeriesControllerProtocolv2.6.pdf

[softwarecrash]

yes, but this is a known old protocol sheet.
let me check later that i make you a version without the static request and added some debug

[kalle3510]

Old protocol, ok. That would be great, thank you in advance. Von: Rocky ***@***.***> Gesendet: Dienstag, 5.

Hello.
I had the similar issue. I my case all hardware is the same except I use ESP01 instead of D1 mini. My MPPT is XTRA4415N-XDS2.
The issue was resolved after checked and corrected wiring between MAX485 and ESP modules.
DE an RE leads used to enable read/write should be connected to Gpio0 on ESP module.
I have checked provided photos wiring , they looks correct according to wiring provided in Wiki, however, when I checked D1 mini board pinout reference it become clear that Wiki may provide wrong scheme for D1 mini board connection.
As mentioned above DE & RE should be connected to Gpio0 and it works for me (ESP01 module)
For D1 mini board Gpio0 corresponds to pin labeled D3. In Wiki we use D1 which is Gpio5.
I see there are different binaries provided for ESP01 and D1 mini boards and I guess differences are in GPIO assignment.
Possible mistake could also happen during GPIO configuration before compile to binary.

Great thanks for this project. I works fine for my XTRA4415N-XDS2.

Follow.the wireing Guide, binarys have different assigment for each ESP Model.
When it Doenst Work, Check Power supply and Set device to ID1 or replace the max485

[kalle3510]

a) Follow the wireing Guide =>done, was also checked before

b) binarys have different assigment for each ESP Model. => used the one suitable form y D1

c) When it Doenst Work, Check Power supply => also tried external supply

d) and Set device to ID1 => checked again, I did

e) or replace the max485 => was done, no change

 I measured the following signals on
Channel 1 TX; Channel 2 D1

Channel 1 RX; Channel 2 D1

Why ist the receive signal RX not synced with D1?

[softwarecrash]

the image for ESP01 have GPIO0 for DE-RE reason is limited pinout
the image for Wemos D1 Mini (and most ohter similar PCB) have have GPIO5 for DE-RE

the signal measurement is from wich side? rs485 or the ttl side?
the measured signal looks like the blue have a short to yelow, so when it send something the yelow will dropped

what say the webserial console?

sometimes users reported a defective rs485 port on the device, have you checked it with pc connection or something else?

[kalle3510]

I am using D1 Mini, so GPIO5 is correct

signal measaurement is at the D1 Mini=> D1 RX TX

blue short to yellow, I also do not understand the voltage drop, but VDD is stable
what about the RX signal (yellow) before DE/RE signal (blue)

The consol tells me no connection.
Also 2 time flashing of the LED.

Yes the EPEVER is working fine. I am using a EPEVER Wifi Adapter 2.4G RJ45 D, but I want to replace it by your device.

[softwarecrash]

What say the webserial? I remember i make it Output the reason Code when fail

The rs485 IS powered over what? 5v or 3v3?

[kalle3510]

WEB serieal: [1] 2 Read Statistical Data Failed

I have tested both: 485 powere from EPEVer with 5V, or from additional supply over WEMO with 5V

[softwarecrash]

well that helps now!
there is a communication issue in the statistic data section, its super fuzzy to find whats exactly wrong without the device that answer with this "wrong" data
let me check it.

what for a device you have?
can you join the discord channel? it needs a bunch of firmwares to find out what data is wrong
