Detailed Description

• ID: tzemt400
• Name: Trane TZEMT400 Z-Wave Thermostat.
• Connection: uart
• Manufacturer: trane

This module allows for monitoring certain elements of a Trane TZEMT400 Z-Wave Thermostat. It was tested with a Trane TZEMT400BB32MAA variant.

    string defaultDev = "/dev/ttyACM0";

    // if an argument was specified, use it as the device instead
    if (argc > 1)
        defaultDev = string(argv[1]);

    // Instantiate a TZEMT400 instance, on device node 13.  You will
    // almost certainly need to change this to reflect your own network.
    // Use the ozwdump example to see what nodes are available.
    upm::TZEMT400 sensor(13);

    // The first thing to do is create options, then lock them when done.
    sensor.optionsCreate();
    sensor.optionsLock();

    // Next, initialize it.
    cout << "Initializing, this may take awhile depending on your ZWave network" << endl;

    sensor.init(defaultDev);
    cout << "Initialization complete" << endl;

    cout << "Querying data..." << endl;
    while (shouldRun) {
        sensor.update();

        // we show both C and F for temperatures
        cout << "Temperature: " << sensor.getTemperature() << " C / " << sensor.getTemperature(true)
             << " F" << endl;

        cout << "Mode: " << sensor.getMode() << endl;

        cout << "Operating State: " << sensor.getOperatingState() << endl;

        cout << "Heating Point: " << sensor.getHeatingPointTemperature() << " C / "

        cout << endl;

Member Function Documentation

float getTemperature

(

bool

fahrenheit = false

)

Return the current measured temperature in Celsius or Fahrenheit.

Parameters

fahrenheit

true to return data in Fahrenheit, false for Celicus. Celsius is the default.

Returns

The temperature in degrees Celsius or Fahrenheit.

Here is the call graph for this function:

string getMode

(

)

Return a string representing the current Mode. This is usually something like "Cool", "Heat", "Auto", etc.

Returns

a string representing the current mode.

Here is the call graph for this function:

string getOperatingState

(

)

Return a string representing the current Operating State. This is usually something like "Idle", or "Cooling".

Returns

a string representing the current operating state.

Here is the call graph for this function:

float getHeatingPointTemperature

(

bool

fahrenheit = false

)

Return the current Heating Point temperature in Celsius or Fahrenheit. This is the temperature at which the thermostat will want to engage Heat.

Parameters

fahrenheit

true to return data in Fahrenheit, false for Celicus. Celsius is the default.

Returns

The Heating Point temperature in degrees Celsius or Fahrenheit.

Here is the call graph for this function:

float getCoolingPointTemperature

(

bool

fahrenheit = false

)

Return the current Cooling Point temperature in Celsius or Fahrenheit. This is the temperature at which the thermostat will want to engage Cooling.

Parameters

fahrenheit

true to return data in Fahrenheit, false for Celicus. Celsius is the default.

Returns

The Cooling Point temperature in degrees Celsius or Fahrenheit.

Here is the call graph for this function:

string getFanMode

(

)

Return a string representing the current Fan Mode. This is usually something like "Auto Low".

Returns

a string representing the Fan Mode.

Here is the call graph for this function:

void update

(

void

)

Query the device and update internal state. Strictly speaking, this is not really neccessary – a device may send this data on it's own at periodic intervals. This method causes OZW to specifically query the device for it's current information. The device may take some time to respond.
