Enhanced Connectivity (OCPP & Modbus): Improved support for OCPP (Open Charge Point Protocol) allows better integration with backend management systems. Modbus TCP/IP updates have also refined communication with home automation systems like Home Assistant.

Drive Green App Integration: Firmware updates enable new features in the Drive Green Next app, such as: vestel wallbox firmware update

Scheduled Charging: Support for off-peak charging to reduce costs.

Device Sharing: The ability to share access to the wallbox with other users.

Web Interface & UI Optimisation: Recent versions improved the WebUI to ensure all maintenance tools and settings fit correctly on the screen, particularly for models with integrated displays. Open the Vestel EVC app

Error Handling: Fixed issues like green LED blinking errors during power optimisation and improved display backlight behaviour. How to Update

OTA (Over-The-Air): Most modern Vestel chargers update automatically via Wi-Fi or Bluetooth through the Drive Green Next app.

Manual Update (USB): For some models, updates can be performed by copying firmware files to a FAT32-formatted USB stick and connecting it directly to the charger's internal display/service port. Vestel Firmware Upgrade - Databeat Knowledge base

Because Vestel manufactures wallboxes for various brands (and under its own name), the firmware update process can vary slightly depending on the exact model and whether it uses the EVB series electronics or older legacy boards. Wallbox reboots and reconnects to OCPP

However, most modern Vestel wallboxes (like the EVC04 Home, EVC11, or white-label units from utility companies) follow one of two paths.

Here is a comprehensive guide on how to update your Vestel Wallbox firmware.

1. Over‑The‑Air (OTA) via Vestel EVC App (Recommended)

1. Open the Vestel EVC app.
2. Select your wallbox from the device list.
3. Go to Settings → Device Info.
4. Tap Check for firmware update.
5. If available, tap Update. The process takes 3–5 minutes.
6. The wallbox will reboot automatically. Do not interrupt power during the update.

Step 3: Navigate to Firmware Update

Tap the settings gear (usually top right or bottom of the device screen). Scroll down to “Firmware Update” or “Device Upgrade.”

11. Testing Scenarios

• [ ] Single remote update success
• [ ] Bulk update (10+ wallboxes)
• [ ] USB update with corrupt file → rejection
• [ ] Power loss during update → recovery mode
• [ ] Downgrade block
• [ ] OCPP timeout → retry logic
• [ ] Invalid signature → reject

Method A: Remote Update (OCPP 1.6J)

Vestel wallboxes support OCPP UpdateFirmware and FirmwareStatusNotification.

Flow:

1. Admin uploads firmware binary (.hex or .bin) to backend server
2. Backend sends UpdateFirmware.req to wallbox with:
   • location (URL to firmware file)
   • retries (e.g., 3)
   • retryInterval (e.g., 60 seconds)
3. Wallbox downloads firmware and reports:
   • FirmwareStatusNotification = Downloading → Downloaded → Installing → Installed
4. Wallbox reboots and reconnects to OCPP
