The client is looking for a battery-operated portable device that manages smart room services.


Engibrains team designed and developed BLE based portable(battery operated) tiny device which controls 8 particular functions of the smart room like brightness level, temperature level, personal assistant, etc. In addition to that, the device is connected with the BLE-based gateway. The mobile application also connected with the gateway as an alternate control point.
