The maximum number of phones that can simultaneously control the lights is limited by the number of online devices in the project.
For example, if there are 10 lights actively online, then up to 10 phones can connect and control the lights at the same time. Each phone needs an individual online device to grant access.
Please note the app still occupies the Bluetooth connection even when running in the background. To allow a new phone to connect, completely force quit the app on the first phone to fully release the Bluetooth connection.
Important: Do not perform editing operations like adding, deleting, or modifying lights, scenes, or groups from more than one phone simultaneously. This can lead to data corruption. Only one phone should edit project details at a time.
