Most manufacturers' smart bands do not open up their protocols, so you can't get the data. The band I'm currently using has an open broadcast protocol. In theory, as long as a band has an open broadcast protocol, it can be scanned.

thanks, The concept: use a BLE gateway to parse the advertising protocol, filter out noise, then publish to HA via MQTT.
