Garden Remote Controller (named SMS Control in the app) is an Android application that lets you control and monitor IoT (Internet of Things) devices, things like lights, water pumps, fans, sensors, and alarms, by sending text messages (SMS) from your phone. The key advantage is that no internet connection is needed on either end: it works purely over the cellular SMS network, making it useful for remote locations like gardens, farms, or off-grid installations where Wi-Fi or mobile data may be unreliable. The app presents a grid of toggle switches and action buttons. Tapping a control sends a formatted SMS command to a phone number you configure, a number attached to the IoT device. The IoT device reads the SMS, acts on it, and sends a status reply back. The app receives that reply, parses it, and updates the display to show the current state of each device. It also handles real-time alerts for motion detectors and door sensors, lets you schedule timed actions called alarms, and keeps a full conversation log of commands and responses. You would use this if you are building or managing a DIY home automation or remote monitoring system that operates without an internet connection, and your hardware responds to SMS commands. The app requires Android 7.0 or higher and is built in Java using standard Android development tools. Setup involves cloning the repository, opening it in Android Studio, and running it on a device or emulator, or installing a prebuilt APK from the releases page.
