SMS Temperature Alert (No Power/Output Change)
6.1. Setting the Temperature Range Parameters
This function sets the temperature parameters for an automatic
SMS temperature alert. When the room/environment
temperature goes out of the programmed range Powertxt® will
send an SMS alert to the master user and any additional users.
Note – When the temperature range has been set successfully
the temperature parameters will be saved in Powertxt®.
These settings are saved in Powertxt® and will remain until the
socket is reset to its factory settings or the settings are changed
by this method again. If the socket loses external power or is
turned off these parameters are still saved.
Please send the following SMS command to set the temperature
values: #170#MinimumTempValue#MaximumTempValue#
e.g. #170#05#20#
When the room/environment temperature goes below 5 degrees
centigrade or above 20 degrees centigrade Powertxt® will send
an SMS alert.
Once the temperature parameters have been set the function
needs to be turned ON/OFF (see points 6.2 & 6.3.).
6.2. SMS Temperature Alert – ON
Please send the following SMS command to turn the SMS
Temperature Alert ON: #170#1#
6.3. SMS Temperature Alert – OFF
Please send the following SMS command to turn the SMS
Temperature Alert OFF: #170#0#
Additional Commands
7.1. Signal Strength
The signal strength scale is 0-33.
Please send the following SMS command to check the SIM
mobile network signal strength: #AM#7#
Note - a reading lower than 10 is a low signal, Powertxt® will
still function with a poor mobile signal however it may affect
the power loss messages depending on how poor the signal
strength is. Unless the signal is very low it shouldn’t affect any
other messages providing mains power is connected. We
recommend you use a SIM with good mobile signal strength
or move Powertxt® to a different area where possible.
