Little GSM
Little GSM starts or stops your borewell or open-well pump from anywhere by SMS, a missed call or the Green Remote app on Android and iPhone. Voltage, load current and motor status come back to your phone, with voice replies in your regional language. It works on a normal SIM, so a basic phone is enough in the field.
Send a text. Your pump starts.

Send my nameplate photo on WhatsAppDoes the Little GSM controller need internet or a smartphone?
No. It works on a normal SIM using SMS and missed calls, so any mobile phone can control it. With a smartphone you can also use the Green Remote app on Android or iPhone.
Which Little GSM model is right for my motor?
Send a photo of your motor nameplate and your starter on WhatsApp, and Green and Green will tell you which model fits.
Will it work with my existing starter?
Yes. It works with DOL, star-delta and single-phase or submersible starter panels. A few very old oil-type starters are not supported, so send us a photo of yours and we will check.
Will it protect my motor if the voltage drops?
Yes. Every model comes with six protections as standard: dry run, phase failure, phase reversal, low voltage, high voltage and overload.
What warranty do I get?
Little GSM controllers come with a 3-year warranty.
Do you install the controller?
Yes. Green and Green engineers install and set it up, and show you the SMS commands and the app on site.
What if something stops working?
Call or WhatsApp us, 7 AM – 8 PM, every day. Near our Udumalpet and Palani offices, a technician reaches your farm within 24 hours. We keep spare parts at both offices.
Is there a price list?
No fixed list. Every quote is made for your farm, so we quote on WhatsApp. Send your motor’s nameplate photo and a photo of the starter panel.
