There is a good place for your purchasing! I bought a GSM control power switch several days ago.We can control the GSM switch though rings or SMS. It can control water heaters, electric motors, electric doors, lights, rice cookers and other appliances. Whether we are on the road or in the office, it is easy and low-cost to control remote appliances.
At first, install SIM card. Install SIM card before power on. According to local operators and signal level, it usually takes about 1 minute to get into the network. When the SIG lights on the panel flash 4 seconds, it enters the GSM network successfully. And then we can set and control the associated operation.
Secondly, set password. GSM switch initial password is 0000. Password command format is “SN + Four old password + NEW + For new password”. For example, if we want to set passwords to “1234”, then we should edit the message “SN0000NEW1234” and issue to GSM switch. As long as we set successfully, we will receive the message “NEW SN SETOK NEW SN IS 1234 (New password).
Thirdly, set master number. GSM control power switch owners can set up 5 groups of master numbers. The setting format is “SN + ****(password) + SET + master numbers”. Such as the user’s password is 1234, if he tries to set 12366668888 to master number, he must edit the message “SN1234SET12366668888” and sent to GSM switch. A message “12366668888SETOK” will be received when the master number is set up successfully. Only the master number can control the outlet by dialing, when the master number dial number of GSM switch, the switch status will change, and then hang up automatically after one second with no cost produced.
Fourthly, ring to control. We also can control the GSM switch by dialing the number of GSM switch. We may hear “You can not answer the phone call, beep…tone, etc.” That set has been successful. If the switch is connected, it will change to disconnected state after a call. If the original state is off, call can be connected.
