Ahoy 
i’m looking for some guys that can help me test my Component for Pytes Battery (E-Box)
The PytesEbox component allows you to pull data from Pytes Batteries into ESPHome.
It uses UART for communication.
Hardware Setup
You can connect to Pytes E-Box using the port labeled Console
Any connections via CAN or RS485 (e.g. to an inverter) are untouched and remain functional.
The console port offers a RS232 interface using a RJ45 connector.
The voltage levels are not TTL-compatible. A RS232 transceive r must be placed between the Batteries and the ESPHome device. MAX3232 -based transceivers have been tested and work well.
If you have multiple batteries you need to connect to the master battery’s console port.
| ESP Pin | Transceiver | RJ45 Pin | Function |
|---|---|---|---|
| GPIO 6 | RX | 3 | TX |
| GND | GND | 4 | Ground |
| GPIO 5 | TX | 6 | RX |
| 3v3 | VCC | NC | Power |
Commands:
| Command | Info | Note |
|---|---|---|
| pwr | Power data show - pwr [index] | |
| pwr N | Power data show - pwr [index] | |
| bat N | Battery data show - bat [pwr][index] | |
| soh N | State of health - soh [addr] | Not ready yet, my FW has no soh  |
