Line 8,373:

The ATLAS system can be remotely controlled over SMS. The '''SMS Actor''' listens to the cellular modem for incoming text messages and reacts to them in two ways: it reports every received SMS over MQTT, and it recognises a small set of predefined text commands that trigger actions directly on the device — without needing network or MQTT connectivity.

This is useful when a device is unreachable over its normal network path (e.g. no internet, VPN down, misconfigured mobile connection) but still has GSM/SIM coverage. An operator can send a plain SMS to the device's SIM number to remotely reboot it, reset its mobile connection, toggle its digital outputs/relays, or manage SSH/mobile data/VPN.

The SMS Actor does not expose a request/response MQTT command interface for external callers, like other actors (e.g. the eMMC actor). It is event-driven: it reacts to SMS messages arriving on the modem and publishes results to MQTT. There is no <code>.../runtime/in</code>topic for external callers to send it commands over MQTT. Internally, the actor does use an MQTT request/response bridge to the Digital Outputs and Relays actors to carry out the <code>OUT##</code>/<code>RL#</code> commands (see Command execution).
