This device is designed to control the matrix intercom using Zigbee.
Using zigbee2mqtt you can:
- Receive a notification when the intercom rings. (also support direct bind)
- Mute the sound on the intercom handset.
- Automatically or manually open the door or hang up when the intercom rings.
There are 4 work modes:
Never
- ordinary work mode, use a handset to controlOnce
- one-time open door when intercom ringsAlways
- open door when intercom ringsDrop
- hangs up all intercom rings, right after the start
You can change the operating mode using z2m or by short press the button. (< 1000ms)
After pressing the button, the LED will flash at 4 Hz.
The number of flashes indicates the current operating mode.
You can control sound mode using z2m or by long-press the button. (1000ms < X < 5000ms)
After pressing the button, the LED will flash at 1.5 Hz.
One flash - OFF, two flashes - ON.
In Gerber PCB v1.0 committed on Apr 14, there are some errors in the silkscreen layers:
- 'Line-' and 'Phone-' are reversed.
- '+' and '-' are also reversed.
Just plug by swapping.
The problem of cross-calls to other apartments:
it was revealed that the intercom circuit is closed through the reverse diode of the u2 transistor (thanks to @Alex_AW)
to prevent it, you need to add a diode according to the diagram:
If you want to use the battery version without a handset, do not turn off the sound in z2m, but use an external resistor to emulate the intercom handset, according to the diagram:
Reset to FN by reboot the device 5 times with intervals of less than 10 seconds.
Reset to FN by pressing and holding BTN for 5 seconds.
LED will flash during reset.

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 can 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 device supports the 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.
