v1.0.0-alpha.0

This alpha release introduces the highly-requested SMS feature and includes significant internal improvements. Please note: this is a pre-release version.

Added

• Initial SMS support: Experimental SMS sending capability via GSM modems.
• New type: sms configuration parameter to enable SMS mode.
• Support for GSM 7-bit alphabet.

Changed

• Major code refactoring: Restructured internal codebase with clear separation between call and SMS logic.
• Improved modem connection handling and error management.

Fixed

• Enhanced AT command response parsing with better timeout handling.
• Improved error handling for SMS-specific modem responses.

Warning

Breaking Changes Coming in stable v1.0.0

• The current configuration.yaml setup will be replaced by a GUI-based configuration flow (#16).
• The action names notify.call and notify.sms will be changed.

Note

SMS Limitations

• Only GSM 7-bit alphabet is supported (basic Latin characters, digits, common symbols).
• This is an experimental feature - track progress and report issues in #17.
• SMS and call configurations can coexist in the same configuration.yaml: simply add both with the same device path.

Configuration Example

notify:
  - name: call
    platform: gsm_call
    device: /dev/serial/by-id/usb-HUAWEI_Technology_HUAWEI_Mobile-if01-port0
  - name: sms
    platform: gsm_call
    type: sms
    device: /dev/serial/by-id/usb-HUAWEI_Technology_HUAWEI_Mobile-if01-port0

Full Changelog: v0.4.3...v1.0.0-alpha.0

v0.4.3

Fixed

• Added proper error handling for Huawei modems.
• Fixed incorrect call statuses: increased the call status polling interval to prevent overwhelming of some modems (like Huawei E1550), which was causing incorrect “NOT ANSWERED” statuses instead of “DECLINED”.

Full Changelog: v0.4.2...v0.4.3

v0.4.2

Changed

• Faster and more robust modem communication. The core AT command handler has been rewritten to use non-blocking, line-based async reading. This eliminates unnecessary delays, improves overall responsiveness, and provides a foundation for features like SMS support, modem state, and signal monitoring (see issues #17 and #4).

Full Changelog: v0.4.1...v0.4.2

v0.4.1

Added

• New dial_timeout_sec parameter to configure dial timeout separately from call duration (#8).
• Support for the upcoming Home Assistant 2025.5.

Changed

• Slightly decreased sleep durations for the GTM382 dialer.

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Added

• Support for GTM382-based modems: Globetrotter HSUPA and compatible (#6).

Changed

Fixed

• Ensure modem connection is properly terminated on exceptions.

---

Добавлено

• Поддержка модемов на базе GTM382: Globetrotter HSUPA и совместимые (#6).

Изменено

• Добавлен таймаут для операций чтения ответа от модема (#7).

v0.3.0

Changes

• New gsm_call_ended event is fired, indicating whether a call was declined or answered.
• Now a phone call hangs up immediately after the callee has answered.
• Call duration is now counted from the moment the called phone starts ringing.
• Now error messages are displayed when making a phone call from the developer tools UI (in other words, exceptions aren't suppressed).

gsm_call_ended automation example

automation:
  - alias: "Disarm the security alarm when a call is declined"
    triggers:
      - trigger: event
        event_type: gsm_call_ended
        event_data:
          phone_number: "79999999999"
          reason: "declined" # declined/answered/not_answered
    actions:
      - action: alarm_control_panel.alarm_disarm
        target:
          entity_id: alarm_control_panel.security
