To configure the modem, use the modem settings tab (Main Menu→SMS messages):
Fields characterizing the properties of the modem element in a system:
Status – the state of the cellular network;
- Operator – the state of the cellular network;
- Signal level – the signal level;
PIN code – pin-code of sim-card;
SMS center number – SMS service center number, leave it blank to auto-detect;
List of allowed phone numbers – list of numbers from which SMS commands are allowed. To separate numbers, use a space. Incoming SMS messages from other numbers are not processed. Supports up to 10 phone numbers (100 for VT9xx systems)Warning We highly recommend writing the SMS center number in this field manually. Some SIM cards have problems with auto-detect features.
.
- Request current balance – the number on which the account balance is requested, to see the answer, click on the "OK" button and wait for an answer, which will be shown in the log;
Info USSD is not supported in LTE mode. The USSD query has a specific format, usually starts with an asterisk, for example: *111# or *222*
Do not enter the phone number in this field.
Some operators abandoned the use of USSD and do not support it. - Clear SMS list – clear list of SMS messages.

If these items do not fit your situation, try to restart the monitoring system. Also, check the sending of messages from your mobile phone.
SMS commands
SMS commands are used for remote management by the monitoring system. Using these commands, you can read the system status, the status, and the measured value of individual sensors and a group of sensors, as well as control the relay switches (outlets). The phone numbers from which the remote control will be made must be added to the list of allowed numbers in the modem parameters editing window (Main menu → SMS messages → List of allowed phone numbers).

In response to each SMS command, an SMS response message arrives, in case of an erroneous command, SMS with an error description and an example of the command comes. In one SMS message, there can be only one command for one element.
System, sensor, relays (outlets) status reading commands
Syntax. get [ID] or get [name], where ID is the "ID" number of the element, "name" is the name of the element. The get field is not case sensitive, you can use Get, GET. The name field is case-sensitive and must be enclosed in quotes. Also, the name of the requested sensor must be unique, otherwise, the answer may be incorrect.
Description. The command requests the status of the sensor or relay (sockets) and sends a response SMS to the phone from which the command came, describing the status of the sensor.
get system - get information about the system. The response contains the system device type, firmware version, system state, IP address, etc. Responses look like this:
| Code Block | ||||
|---|---|---|---|---|
| ||||
System: VT335
Firmware: 2.7.4 b570
State: normal
Hostname: monitoring_unit_1
IP: 192.168.0.193 |
get [group name or ID] - get information about the group of sensors. Response contains a description of the group and a brief description of all the modules and sensors in the group. Responses look like this:
| Code Block | ||||
|---|---|---|---|---|
| ||||
Group: test group [3001]
State: normal
Description: here if available
Analog-4[102001] normal 0
Onboard Temperature[201001] normal 30.20 C
Onboard Voltage DC[203001] normal 12.21 V |

If there are many sensors in the group, the answer may be too large. |
get [sensor name or ID] - get information about the sensor. Responses look like this:

Element: Temperature-1 [201003]
State: normal
Value: 27.5 C |
Commands for setting the status of the relay (sockets)
Syntax. set [ID] [state] or set [name] [state], where ID - the "ID" number of the element, "name" is the name of the element, "state" is the state to which you want to switch. The set and state fields are not case-sensitive. The name field is case-sensitive. The state field takes one of the following states: on - enable, off - disable.
Description. The command will switch the relay or socket under the state parameter and send the reply SMS to the phone from which the command came, about the result of the command.
Illustration.
set '302001' on - turn on relay number 302001;
set 'Outlet-1' on - turn on relay Outlet-1;
- set '302002' off - turn off relay number 302002;
set 'Outlet-2' off - turn off relay Outlet-2.
Response. In this case the response message looks like this: The element (element name) was switched on or The element (element name) was switched off.
Relay (Socket) pulse setting commands
Syntax. set [ID] pulse {duration} or set [name] pulse {duration}, where ID is the "ID" number of the element, "name" is the name of the element, duration is the delay time in seconds. The name field is case-sensitive. The value range of the duration field is from 1 to 120. The duration field does not need to be specified, the previously set value is applied.
Description. The command switches the status of the relay (sockets) to the opposite one twice, with the time delay specified as the duration parameter in seconds.
Illustration.
set '302003' pulse 15 - the impulse to the relay number 302003 with a delay of 15 seconds;
set 'Relay-1' pulse 110 - the impulse to the relay named Relay-1 with a delay of 110 seconds;
- set 'Outlet-2' pulse - sending a pulse to an outlet with the name Outlet-2 with a previously set delay.
Response. In this case the response message looks like this: The element (element name) was switched.
Logic control commands (logic)
Syntax. logic [id] [state] {duration}, logic * [state], where ID – the "Logic number" of the logic (the symbol '*' for all logics), state - the state into which the logic goes ("off", "on"), duration - the time of logic shutdown in seconds. All fields are case insensitive.
Description. Commands disable or enable logic. The duration is indicated only when one logic is disabled.
Illustration.
- logic 1 off 10 - disabling logic with the number 1 for 10 seconds;
- logic 1 on - the inclusion of logic with the number 1;
- logic * off - disabling all logic for 24 hours;
- logic * on - including all logic.
Response. In this case the response message looks like this: OK.
