After the PID is transferred to another IoT account, will the originally bound hotspot still be effective?

No, the hotspot is strongly bound to the IoT account where the PID is located. Once the PID is transferred, the binding relationship between the hotspot and the PID is released. It is recommended to authorize the PID to the relevant parties with the relevant permissions through space authorization. If you need to cancel or change the binding relationship between the hotspot and the PID, please submit a work order to contact Tuya related personnel for processing.
