People search "automatic motor on off system" when they are tired of walking to the switch. They want the motor to start when water is low and stop when the tank is full, or they want to press a button on a phone. Those are related and not identical. A timer can run a motor for a fixed time and still overflow the tank or run it dry. A remote button can start the motor and still need a person to remember to stop it. Level-based on and off needs a level and a switch. Water Gauge publishes both: thresholds and schedules on the home page, a controller that the app can command, and a level manager that supplies the reading.
Manual, scheduled, and level-based
The controller test has a manual step: turn the motor on and off from the app and watch the starter. That is remote control. The same page then asks for a test of automatic control. The home page says you can create schedules and set thresholds for automatic on and off. The app page says you can turn the pump on or off depending on the water level. So the published automatic behaviour is tied to the app and to the level, not to a secret sensor inside the motor winding. If you only install the controller, you have the remote and whatever automatic mode the app shows without a tank reading. If you want the motor to follow the tank, install the sensor and level manager too. That full set is wireless water automation.
The controller uses an AC adapter at the starter. It is not the solar box. Solar is the level manager on the roof or at the field tank. Mixing them up produces a quote for the wrong power supply. Solar monitoring is the reading alone. The pump controller page is the switch.
The starter decides the wiring, not the slogan
Relay connections are described for a submersible motor starter. Other starters follow their own instructions and a compatibility check. An automatic on off system that ignores the existing panel is how motors get wired wrongly. Show the starter to the electrician who already knows it. Borewell owners should read borewell automation. Houses with a simple starter should still say what the starter is when they call.
Dry run and overflow are the two failures on and off is supposed to prevent. Overflow needs the motor to stop when the tank is full. The sensor has to be mounted at a real full level. The notification and the motor command both need a test, which the product pages already require. A time from sensor to contactor is not published. Overflow explains why the overflow pipe should remain.
Hindi search, same machines
The same request shows up as "automatic motor on off" and as "pani ki tanki automation". The hardware does not change. The Hinglish guide uses the same limits: no invented price, no invented range, sensor in the tank, controller at the starter. Homes and farms are the two places this search usually comes from.
Call +91 70004 65454 or open the contact page. No price list is on the site. The office is in Indore, Scheme No 140. See the FAQ and how it works. The app is Android, package com.waterguage.water_guage. Synetal Solutions Pvt Ltd is the company named with the product. An iPhone version is not described, so do not buy on the assumption that every phone in the house can install it.
When you test, separate the three behaviours so you know which one you bought. First, on and off from the phone while you watch the starter. That is manual remote control. Second, a schedule if you asked for time-of-day running, watched once so you know it is not only a picture in the app. Third, a level threshold, watched once while the tank actually approaches the point you set, so the motor stops or starts because of the level and not because someone pressed the button. If the third test has no level on the screen, the level manager is missing or offline. If the first test does nothing, the controller or the starter wiring is the problem. Fixing the solar panel will not move a starter that was never connected. That separation is the whole of an automatic motor on off system as this website describes it.
If you want this in one line for a family member: the phone can start and stop the motor, the roof unit tells the phone how full the tank is, and the motor only follows the tank when both units are installed and the starter connection has been tested. Call +91 70004 65454 with that sentence and your starter type. The reply should name which box you need. It should not be a single unnamed kit with a price copied from another site.
