I have two Ali-Express power monitoring smart plugs using the WL2S WiFi chip. I have flashed both with ESPHome (2025.11.01-dev), using the manufacturer's LN882H_CMD_TOOL (ltchiptool fails).

The devices appear on the home network with the SAME MAC address and they do not accept manual IP assignment.

The MAC access is always: 00:50:C2:5E:10:88, for both devices.

I decided to use the LN882H_CMD_TOOL to read the MAC address: It returns FF:FF:FF:FF:FF:FF

I decided to use the LN882H_CMD_TOOL to burn unique MAC addresses to both chips. Although the tool confirms the correct address, they still appear under the "original" address in the WiFi network, so I can's have both devices on the network at the same time.

It appears LibreTiny and/or ESPHome is not recognizing the MAC address in the chip at all.
