Is there a company that uses SMS to remotely control valves?

Valves and pumps can be remotely controlled by SMS. Take the remote control of water pump by SMS as an example. When a mobile phone is used to remotely control a water pump or a valve, an AC contactor is needed to indirectly control the working state of the water pump or the valve. The wiring method is as follows:

When in use, put the mobile phone card into the card slot of the mobile phone water pump remote controller, and then connect the water pump, the AC contactor and the mobile phone water pump remote controller; After the connection is completed, another mobile phone sends a short message to the card number of the remote control card slot of the mobile phone water pump, and finally realizes the setting and monitoring of the working state of the water pump.
