6.3 Temperature sensor querying

Querying of the temperature sensor is only possible via SMS and querying is not possible via voice commands (DTMF tones).
The temperature reading is available with 1 °C resolution. If no sensor is connected to the TEMP terminals, querying of the
temperature will produce a reply SMS with the message "TEMP NOT VALID".
Querying of the temperature sensor during an active alarm condition produces a reply SMS with the message "TEMP xx C
ALARM"
