Hi everyone,

I’m reaching out to report a specific connectivity issue with the **EV Charging Station NS 22kW**.

**The Problem:** The station is unable to connect to a Wi-Fi network if the **SSID is hidden**. As soon as I disable the “Hidden” attribute in my controller and broadcast the SSID, the station connects immediately and works perfectly. Once hidden again, the connection is lost and cannot be re-established.

**My Network Setup:**

- **AP/Controller:** Ubiquiti UniFi.

- **WiFi Profile:** Enhanced IoT Connectivity (minimized restrictions for better compatibility).

- **Security:** WPA2.

- **Frequency:** 2.4 GHz (standard).

**Observations:** It seems the station’s Wi-Fi module or firmware doesn’t properly handle “Passive Scanning” or probe requests required to find hidden networks. Even with high-compatibility settings like “Enhanced IoT” in UniFi, the hidden status remains a dealbreaker.

Given this is a standard Wi-Fi protocol feature, it is quite inconvenient to be forced to broadcast the SSID just for one device.

Has anyone else encountered this? Is there a planned firmware update that addresses the handshake logic for hidden SSIDs?

**Hardware details:**

- Device: Victron EV Charging Station NS 22kW

- Connection: Wi-Fi

Looking forward to any insights or workarounds.
