Device ID (SW1)
Your application software may use device ID to seek and control the
device, this means you must assign uniquely identifies for same devices
in the same control network, the device ID can be 0 to 255.
Otherwise, your application software may use serial number to seek and control the device in, then
the device ID is not meaning.
After change device ID, turn off and turn on power, the new device ID take effect.
