To control lights from the AsteraApp, a Bluetooth Bridge (=BTB) is required. It consists of “Bluetooth” for the connection with the App and “Bridge” which means that it transmits commands to the other Astera lights. Both parts include 2-way communication so the lights can send information back to the app.
Until 2020 the AsteraBox was the only Bluetooth Bridge but recently Astera has been building the BTB technology into more and more lights. We still recommend an AsteraBox as it has a longer battery life and is more portable but for smaller setups or if no AsteraBox is available, a BTB-enabled light also works well.
