Failed to prepare configuration #5

Closed PiotrRowinski closed 1 year ago

PiotrRowinski commented 1 year ago

Hi!

I'm not able to prepare the configuration when trying to include foxess_t_series.h:

INFO Reading configuration /config/esphome/esp32-foxess.yaml... INFO Generating C++ source... INFO Compiling app... Processing esp32-foxess (board: esp32dev; framework: arduino; platform: platformio/espressif32 @ 3.5.0)

Any ideas?

Thanks in advance!

Are you sure you didn't change anything, like renaming the component? Just try using the Github files without changing anything.

PiotrRowinski commented 1 year ago

I repeated all the steps again using the files directly from GitHub and leaving the same names and now I'm able to prepare the configuration and include foxess_t_series.h without any errors- thanks!

But unfortunately, all the values of the sensors are in an unknown state :(

Everything is connected as shown on the Hardware Setup diagram and the output of the buck converter is 5V. Logs from the ESP32 with additional UART debugging:

What model inverter do you have? Those serial messages look nothing like what a Foxess T-Series would transmit.

PiotrRowinski commented 1 year ago

It is a Foxess T5 PV Grid-tied inverter - https://static.fox-ess.pro/upload/T_G2_PL_f9fb5ece7a.pdf. Maybe some additional rs-485 configuration is required on the inverter side?

BTW would You be able to share examples of expected serial messages?

This is what a typical output looks like: 7E 7E 02 63 23 ED AC 00 E8 00 00 17 E8 00 00 09 5B 00 55 13 87 07 F1 09 53 00 55 13 87 07 EA 09 63 00 55 13 87 07 F8 14 DA 00 60 00 00 0E 7F 00 1B 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2C 00 2C 00 2C 00 82 00 00 55 5A 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 03 50 78 00 10 00 00 00 00 00 1A 00 00 00 00 00 00 00 00 00 00 02 21 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 00 02 00 00 00 00 03 E7 FF 64 17 EA 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FF FF 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 3F E5 00 00 00 00 00 00 00 00 00 00 00 00 C6 63 E7 E7

It always starts with 7E 7E and ends with E7 E7. Most of the Info is in the beginning of the message. In the middle there are a lot of zeros. Total length is either 165 or 245 bytes, depending on the firmware installed on the inverter.

After changing the CT/Meter setting (from Disable to Comm), I started getting similar serial messages (with 7E 7E at the beginning), and everything is working fine now!

Thanks for your support!
