Yes, you can.
SwitchBot devices can be discovered by any SwitchBot App users nearby (Bluetooth and location permission on the smartphone(s) need to be turned on). Optionally, you can set a password to SwitchBot (the Bot) to prevent unauthorized access. SwitchBot Hub, Hub Plus or Meter can be paired with multiple SwitchBot accounts as well.
Moreover, logging in on multiple devices simultaneously with the same SwitchBot account is also supported.
