🔧 Troubleshooting

❌ No Data from Batteries

🔴 Symptom: All sensors show “unavailable” or “unknown”

✅ Solutions:

1. ✅ Check physical wiring connections (TX/RX crossed)
2. ✅ Verify RS232-TTL module power (3.3V not 5V)
3. ✅ Confirm baud rate is 115200
4. ✅ Check ESPHome logs for UART errors
5. ✅ Verify Pytes console port is active (some models require activation)

⚠️ Wrong Data or Garbled Output

🔴 Symptom: Sensors show incorrect values or random characters

✅ Solutions:

1. ✅ Double-check TX/RX wiring (may be swapped)
2. ✅ Ensure ground connection between ESP32 and RS232 module
3. ✅ Verify 8N1 UART configuration
4. ✅ Check for loose connections
5. ✅ Try reducing update interval (increase poll_s)

📡 Device Disconnects from WiFi

🔴 Symptom: ESP32 goes offline periodically

✅ Solutions:

1. ✅ Move ESP32 closer to WiFi router
2. ✅ Use stronger WiFi antenna
3. ✅ Set static IP in router
4. ✅ Enable AP fallback mode
5. ✅ Check power supply (use quality 5V 2A adapter)

🔋 Only Bank Sensors Work, Individual Batteries Don’t

🔴 Symptom: Summary sensors update but B1-B6 sensors remain unavailable

✅ Solutions:

1. ✅ Verify num_batteries matches actual battery count
2. ✅ Check that all battery IDs are defined in configuration
3. ✅ Ensure batteries are properly connected in series
4. ✅ Review ESPHome logs for parsing errors

🌡️ High Temperature Readings

🔴 Symptom: Temperature sensors show unusually high values

✅ Solutions:

1. ✅ Check if temperature is in Fahrenheit (default) or Celsius
2. ✅ Verify battery ventilation
3. ✅ Confirm sensor calibration
4. ✅ Check for actual overheating condition

💻 Compilation Errors

🔴 Symptom: ESPHome fails to compile the configuration

✅ Solutions:

1. ✅ Update ESPHome to version 2025.1 or newer
2. ✅ Verify ESP-IDF framework is selected (not Arduino)
3. ✅ Check minimum chip revision setting (3.1)
4. ✅ Ensure all required IDs are defined in sensor templates
5. ✅ Review YAML syntax for errors

How does this software work?

ESPHome component reads the RS232 serial port with configurable frequency (default 30s), parses the battery data and sends it to Home Assistant via the ESPHome API. Home Assistant autodiscovery is built-in, so all sensors will show up automatically.

A signal converter from RS232 to TTL is needed between Pytes serial console port and ESP32 UART pins.

Program creates the following sensors for each battery:

• Bank level: voltage, current, temperature, SoC, status
• Individual batteries (1-6): voltage, current, temperature, SoC, serial#, model, firmware, status, volt_status

Hardware used:

ESP32 board –––––––––––––– tested on ESP32 WROOM 38 pins / ESP32 DevKitC

RS232 to TTL converter —————– tested on MAX3232 module

RJ45 to RS232 DB9(male) cable –––– tested on standard console cable

Simple connection flow:

ESP32 [UART pins GPIO16/17] -> TTL to RS232 converter -> DB09 to RJ45 cable -> Pytes RJ45 console port

Connection with RS232 to TTL converter using RJ45 to RS232 DB9(male) cable - TESTED:

ESP32 Pin: 16 RXD2 ------ RX converter  RX  DB9 Female ------ DB9 Male console cable RJ45 Pin: 3 TXD 
ESP32 Pin: 17 TXD2 ------ TX converter  TX  DB9 Female ------ DB9 Male console cable RJ45 Pin: 6 RXD 
ESP32 PIN:     GND ------ GND converter GND DB9 Female ------ DB9 Male console cable RJ45 Pin: 4 GND 
ESP32 PIN:    3.3V ------ VCC converter     DB9 Female ------ DB9 Male console cable RJ45

UART Configuration:

• Baud Rate: 115200
• Data Bits: 8
• Parity: NONE
• Stop Bits: 1

Important: Both connection types work, but respect the PYTES console port pinout. Main source of issues is incorrect TX/RX connection. If something goes wrong, swap RXD and TXD on one side.

Normal Operation

When ESP32 is powered and configured:

1. Device connects to WiFi
2. Establishes UART communication with Pytes battery
3. Reads serial data at configured interval (default 30s)
4. Automatically creates device and sensors in Home Assistant
5. Updates sensor values continuously

After firmware updates it is recommended to delete previous devices in Home Assistant and let them be recreated at next boot.
