The demand for custom hotspots can be achieved by purchasing value-added services of "Hotspot Customization". There are two situations when modifying the hotspot name: 1. If you haven't placed an order yet, please specify the custom part when placing your order. The custom part must be no longer than 12 characters, including both Chinese and English. Special characters and emoticons are not supported. The hotspot name will be: SL (fixed) – XXXXX (custom part) – XXXX (last 4 digits of the MAC address, automatically generated by the system, no maintenance required), for example, SL-smartlife-3012. For more information, please refer to the document: https://developer.tuya.com/en/docs/iot/customized-hotspot?id=Kafuzks2ue6ur 2. If you have already placed an order and need to modify the hotspot name, the hotspot owner should contact their account manager.
