This is the description of the TCP/IP protocol for the Temperature Bricklet. General information and technical specifications for the Temperature Bricklet are summarized in its hardware description.
A general description of the TCP/IP protocol structure can be found here.

Returns the temperature of the sensor. The value has a range of -2500 to 8500 and is given in °C/100, e.g. a value of 4223 means that a temperature of 42.23 °C is measured.
If you want to get the temperature periodically, it is recommended to use the callback CALLBACK_TEMPERATURE and set the period with set_temperature_callback_period.

Sets the I2C mode. Possible modes are:
If you have problems with obvious outliers in the Temperature Bricklet measurements, they may be caused by EMI issues. In this case it may be helpful to lower the I2C speed.
It is however not recommended to lower the I2C speed in applications where a high throughput needs to be achieved.
New in version 2.0.1 (Plugin).

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.
The position can be 'a', 'b', 'c' or 'd'.
The device identifier numbers can be found here.

Response: | no response |
Sets the period in ms with which the CALLBACK_TEMPERATURE callback is triggered periodically. A value of 0 turns the callback off.
CALLBACK_TEMPERATURE is only triggered if the temperature has changed since the last triggering.
The default value is 0.

Returns the period as set by set_temperature_callback_period.
Function ID: | 4 |

Response: | no response |
Sets the thresholds for the CALLBACK_TEMPERATURE_REACHED callback.
The following options are possible:
Option | Description |
---|---|
'x' | Callback is turned off |
'o' | Callback is triggered when the temperature is outside the min and max values |
'i' | Callback is triggered when the temperature is inside the min and max values |
'<' | Callback is triggered when the temperature is smaller than the min value (max is ignored) |
'>' | Callback is triggered when the temperature is greater than the min value (max is ignored) |
The default value is ('x', 0, 0).

Response: | no response |
Sets the period in ms with which the threshold callback
is triggered, if the threshold
keeps being reached.
The default value is 100.

Returns the debounce period as set by set_debounce_period.
Function ID: | 8 |
---|---|
Response: |
|
This callback is triggered periodically with the period that is set by set_temperature_callback_period. The response value is the temperature of the sensor.
CALLBACK_TEMPERATURE is only triggered if the temperature has changed since the last triggering.
Function ID: | 9 |
---|---|
Response: |
|
This callback is triggered when the threshold as set by set_temperature_callback_threshold is reached. The response value is the temperature of the sensor.
If the threshold keeps being reached, the callback is triggered periodically with the period as set by set_debounce_period.
