## Description

Blue Switch is a versatile Chrome extension that enables you to control 2, 4, or 8 channel Relay Modules equipped with Bluetooth Low Energy (BLE) directly from your smartphone. Designed as an alternative to the TwoSwitchBle app, it allows connection with multiple modules simultaneously. You can assign clear aliases to each module and relay for easy identification, such as 'Relay 1' or 'Ambient Light'.

Security is a priority with Blue Switch, offering the ability to change the default module password (usually '12345678') to a custom eight-digit password. Ideal for electronic lab projects and home automation, Blue Switch simplifies managing BLE relay modules for various applications.
