GSM / IoT Remote Motor Starter

A GSM or IoT remote motor starter is a SIM-based controller that switches a single- or three-phase irrigation pump on and off through any major Indian GSM network (Jio, Airtel, BSNL, Vi). It is functionally equivalent to a Gsm Mobile Pump Starter and the terms are used interchangeably in the Indian market.

Function

The controller monitors supply phase voltages and current draw, and accepts on/off commands through a missed call, SMS or smartphone app. The unit drives the motor's contactor and is wired with current and voltage sensors at the supply side, plus dry-run probes inside the bore casing or pumphouse.

Design and specifications

The starter accommodates 230 V single-phase and 415 V three-phase supply. Standard protections include dry-run cut-off, overload, single-phase prevention, phase-failure detection and over/under-voltage protection. Many models support up to five scheduling timer windows. Retail price for single-phase units is Rs 4,000-6,000.

Operation

After commissioning, the cultivator can start or stop the pump from anywhere with mobile coverage. The unit logs each switching event, fault and supply restoration to the registered mobile number, and many controllers expose a smartphone app for graphical monitoring.

Subsidy and adoption

While not on every state SMAM positive list, GSM starters are supported under various Discom and agriculture energy-efficiency programmes. Indian manufacturers include Nelsotech (P106 three-phase model), Dyulabs (Varun S2), RMG Automation, Indusmate, Accord and GIC India.
