Firmware 2022 801 can´t read nor write - controller in reboot-loop

[klusou]

Hi, I have the 1200w 48v Modell with display. it seems like newer firmware doesn´t send any status codes. The "Esp-Soyosource-Controller" also doesn´t get values but the "rs485" shows in the display and I can send a target Power. So I think the Hardware is okay but because there are no values - this firmware crashes. Is there anyone out there with a solution ?

Whats about this "displayport" Didn´t find any description to it.

Kind Regards

This project does work for silent inverters too in general. What do you mean by "this firmware crashs"?

[syssi]

Do you use MQTT or the native api? Could you provide some logs of the crash?

Okay Im getting the logs later because Im at work. Testet both - mqtt und Homeassistant mode in mqtt mode its a login - logout reboot -login loop in Homeassistant mode it send 3 times something to serial that starts with 24 ...., then sets some defaults - waits till some timeout - would say 5 to 10 sec. then reboot - loop I used the example yaml with and without display, because I don´t know what that display port thing stands for - The Soyosource with display or some device with an Serial Port for a Display ...

[syssi]

I've pushed reduced YAML configuration examples:

https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/blob/main/esp32-limiter-example.yaml https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/blob/main/esp8266-limiter-example.yaml

Please flash one of these examples and provide the logs / crashs later the day. I will try to get an idea what's going on.

Hi, I flashed my 2 boards with esp32 and esp8266 (D1 mini) and that settings; Both stopped to reboot. The ESP32 didn´t work with either the RS485 boards (SOYOSOURCE shows no RS485 in Display) and power-demand value has no effect. The logs from ESP32 are:

The "old" D1 mini (8266) worked - RS485 in display of SOYOSOURCE and also with both RS485 Boards and power-demand value is working. Maybe the Pinout is not all the same... Kind Regards

To which GPIOs of the ESP32 did you attach the RS485 converter?

https://cdn.shopify.com/s/files/1/1509/1638/files/ESP32_D1-Mini_480x480.png?v=1611046537 I used the same place as with the older d1 mini. Seems to me like GPO01 an GPO03.

[syssi]

That should have worked. Please double check your RS485 converter and please make sure you didn't swap the TX/RX lines accidently. There are many devices that already come dead from the factory.

Does it work now for the ESP8266 and your setup is stable?

[klusou]

Hi, my ESP8266 is stable and solving my Problem. Because this 2 Boards have same Pinout with tx/rx 5v , GND and 3,3v I made 2 Boards with socket for the D1 mini with each of the RS485 Boards. So I can switch the ESP as I like. That's why I'm pretty sure the RS485 are both running because they work with the older one. Maybe Im going to try some other GPIO on the ESP32 - they seem to have a second RX/TX on GPIO16/17

[syssi]

The ESP32 has a GPIO matrix / IO mux so the hardware UARTs can be routed to any pin. Feel free to attach the RS485 converter to any pin.
