Overview
Currently, the Lomi App only allows one account to be connected to your Lomi, or Lomis. This means that you can connect multiple units to one account but you cannot connect multiple accounts to one or more units.
Lomi 2 (Bloom)
If you did attempt this, you simply wouldn't be able to locate your Lomi 2 (Bloom) on the list of available devices.
Lomi 1 (Classic)
If you attempted to manually add your Lomi's serial number to a separate account, an error would note: "serial number already in use".
