Schematic

PCB size

57.5mm x 27.3mm

DC Power

Support router and end device modes.
Install E18-MS1PA1, E18-MS1PA2 or E18-MS1-PCB.

Battery Power

Support only end device mode.
Install E18-MS1-PCB only!

Do not turn off sound because it turns U2 forever, which will drain the battery much faster.

Since the device is in sleep mode, it cannot receive commands.
But you have the ability to set the button mode or at the time of the call.

If any commands are in the coordinator's queue, they will be executed after a button is pressed or a call is received.

The mode set by the Zigbee command overwrites the mode set by the button.

Binding

The device supports direct binding of an incoming call to the onOff cluster.

For example, you can turn on the light while a call comes to the intercom, for notification in mute mode.
