GSM 문자 알림(SMS notifications via GSM-modem)


The sms integration allows having a local execution SMS notification via Gammu. This is ideal when the internet is offline or when the power goes out.

This integration provides the following platforms:

  • Notify

Configuration

To enable those notifications in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sms:
  device: /dev/ttyUSB2

notify:
  - platform: sms
    name: sms_person1
    recipient: PHONE_NUMBER
  - platform: sms
    name: sms_person2
    recipient: PHONE_NUMBER

Configuration Variables

device

(string)(Required)

The gsm modem device.

To use notifications, please see the getting started with automation page.

If the integration is used with the Home Assistant Operating System, then version 3.6 or higher is required.

For installations not running on Home Assistant or Home Assistant Core using Docker, you must install gammu-dev package:

sudo apt-get install libgammu-dev

Before running for the first time, check that the system recognizes the modem by running:

ls -l /dev/*USB*

Note: When running Home Assistant, you need to install the SSH add-on.

Required Hardware

You will need a USB GSM stick modem.

Huawei modems on Raspberry Pi (and similar) devices

For some unknown reason, the rule that converts these modems from storage devices into serial devices does not run automatically. To work around this problem, follow the procedure to create udev rule on a configuration USB stick for the device to switch to serial mode.

  1. Run lsusb, its output looks like this:
bus 000 device 001: ID 1FFF:342a
bus 001 device 005: ID 12d1:15ca   <-------- Huawei is usually 12d1
bus 000 device 002: ID 2354:5352
bus 000 device 002: ID 1232:15ca

Identify the brand for your GSM modem, copy the brand_Id and product_id (In this case brand_id = 12d1 and product_Id = 15ca)

Set this content in file udev\10-gsm-modem.rules in the configuration USB: (Replace brand_Id and product_id for the numbers reported by lsusb)

ACTION=="add" \
, ATTRS{idVendor}=="brand_Id" \
, ATTRS{idProduct}=="product_Id" \
, RUN+="/sbin/usb_modeswitch -X -v brand_Id -p product_Id"

Here is a sample configuration file:

ACTION=="add" \
, ATTRS{idVendor}=="12d1" \
, ATTRS{idProduct}=="15ca" \
, RUN+="/sbin/usb_modeswitch -X -v 12d1 -p 15ca"

Plug the USB stick, reboot the device, run lsusb again. The resulting product id now should be different and the brand id should be the same. And ls -l /dev/*USB* should now report your device.

If the device is still not recognized, remove the parameter -X from the usb_modesiwtch command and reboot again.
