The RUST Smart Alarm is a deployable electrical entity used to link in-game happenings and alerts directly to a player’s real-life phone via the Rust+ Companion App. Facepunch added electricity components in the Electric Anniversary update on the 7th of December, 2018.
Players may deploy smart alarms on most flat surfaces. When using a Wiring Tool to check for ports, players will find a single Power Out port, as well as a Power In. As the name implies smart alarms are used to alert players via live updates to their phones if they’re being raided.
Requiring 1 power input to function, the premise is fairly simple; once paired (check out our smart device guide), if a device such as an Auto Turret or HBHF Sensor detects non-authorized players within their vicinity, an app message will be sent to the base owner via the Rust+ App letting them know that they’re being raided.
Smart alarms may be found in an assortment of mid-to-high tier crates, as well as drops from a wide range of scientists. Players may also research them directly or invest scrap into the Tier 2 Workbench tech tree.
