## About
|
|
|
|
The ExternalNotification Module will allow you to connect a speaker, LED or other device to notify you when a message has been received from the mesh network.
|
|
|
|
## Configuration
|
|
|
|
<PluginModule name="ext_notification_plugin" rename="ext_notification_module" />
|
|
|
|
These are the settings that can be configured.
|
|
|
|
ext_notification_module_enabled
|
|
Is the module enabled?
|
|
|
|
0 = Disabled (Default)
|
|
1 = Enabled
|
|
|
|
ext_notification_module_active
|
|
Is your external circuit triggered when our GPIO is low or high?
|
|
|
|
0 = Active Low (Default)
|
|
1 = Active High
|
|
|
|
ext_notification_module_alert_message
|
|
Do you want to be notified on an incoming message?
|
|
|
|
0 = Disabled (Default)
|
|
1 = Alert when a text message comes
|
|
|
|
ext_notification_module_alert_bell
|
|
Do you want to be notified on an incoming bell?
|
|
|
|
0 = Disabled (Default)
|
|
1 = Alert when the bell character is received
|
|
|
|
ext_notification_module_output
|
|
What GPIO is your external circuit attached?
|
|
|
|
GPIO of the output. (Default = 13)
|
|
|
|
ext_notification_module_output_ms
|
|
How long do you want us to trigger your external circuit?
|
|
|
|
Amount of time in ms for the alert. Default is 1000.
|
|
|
|
## Usage Notes
|
|
|
|
For basic usage, start with:
|
|
|
|
ext_notification_module_enabled = 1
|
|
|
|
ext_notification_module_alert_message = 1
|
|
|
|
Depending on how your external circuit is configured, you may need to set the active state to true.
|
|
|
|
ext_notification_module_active = 1
|
|
|
|
:::note
|
|
The device must be restarted after the settings have been changed for the module to take effect.

### Alert Types
|
|
|
|
We support being alerted on two events:
|
|
|
|
1. Incoming Text Message
|
|
|
|
2. Incoming Text Message that contains the ASCII bell character. At present, only the Python API can send an ASCII bell character, but more support may be added in the future.
|
|
|
|
#### Bell Character
|
|
|
|
The bell character is ASCII 0x07. Include 0x07 anywhere in the text message and with ext_notification_module_alert_bell enabled, we will issue an external notification.
|
|
|
|
## External Hardware
|
|
|
|
Be mindful of the max current sink and source of the ESP32 GPIO. The easiest devices to interface with would be either an LED or Active Buzzer.
|
|
|
|
Ideas for external hardware:
|
|
|
|
- LED
|
|
- Active Buzzer
|
|
- Flame thrower
|
|
- Strobe Light
|
|
- Siren
|
|
|
|
## Known Problems
|
|
|
|
- This won't directly support a passive (normal) speaker as it does not generate any audio wave forms.
|
|
- This currently only supports the ESP32. Other targets may be possible, I just don't have to test with.
|
|
- This module only monitors text messages. We won't trigger on any other packet types.
