EstateView Software
Powertxt® can be controlled easily by a mobile phone however
for control of multiple Powertxt® units we have developed a
dedicated management software solution called EstateView.
EstateView is an online portal that allows you to control your
equipment just like you would through your mobile phone,

Figure 1
08 09
EstateView makes it much easier to control multiple devices as
you can send the same command to many devices (e.g. setting
up/initialising the devices), power loss alerts all come in to one
central place and from EstateView these alerts can be emailed
out. Note – not all commands for Powertxt® are within
EstateView, just the main control commands. For a free trial of
EstateView please contact your supplier.

Controllin the Power (Output) by Time/Day & Delay
4.1. Setting the Time/Day Parameters
When the time/day has been set successfully the scheduled
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 Powertxt® loses external power or is turned off these
parameters are still saved.
These parameters have to be set first then the function needs to
be turned ON/OFF with a second SMS Command (see points
4.2. & 4.3.).
Please send the following SMS command to set the time/day
control parameters: #129#WorkDay#StartTime#EndTime#
‘WorkDay’ This value lies in the range of ‘0’ to ‘9’, the following
table contains the descriptions of each value.
The ‘StartTime’ and ‘EndTime’ consists of 4 digits (hh:mm) and
works on a 24 hour clock, the ‘StartTime’ and ‘EndTime’ should
be in the same day and the ‘EndTime’ must be later than the
‘StartTime’ during the period.
The power (output) will switch ON at the ‘StartTime’ and switch
OFF at the ‘EndTime’.
eg. #129#5#0730#2130# . Powertxt® will switch power ON at
7.30am and switch power OFF at 9.30pm every Friday.
Value Corresponding Value Corresponding Value Corresponding

18 19
4.2. Controlling the Power (Output) by Time/Day - ON
Once the time/day parameters have been set (see point 4.1) the
function needs to be turned ON.
Please send the following SMS command to turn the control by
time/day function ON: #128#1#
4.3. Controlling the Power (Output) by Time/Day - OFF
Please send the following SMS command to turn the control by
time/day function OFF: #128#0#
4.4. Controlling the Power (Output) by Time Delay – Power
ON
Powertxt® can be set by SMS command so there is a delay in
turning the power (output) ON or OFF.
Note: When the ‘Time Delay’ function is applied the pre-set
‘Time/Day Control’ switching of Powertxt® power (output) will be
over-ridden (e.g. If you send an SMS command to Powertxt® to
turn the power off after 10 minutes and then you send an SMS
command to turn the power off 2 minutes later the ‘time delay’
function will be cancelled as Powertxt® power is now off. This is
also the same if Powertxt® is set to be on between 9am-5pm
Monday to Friday and an SMS command is sent to Powertxt®
to turn it off at 3pm (or by pressing the Power Control button on
the side). To reset these functions they need to be turned on
again by sending #128#1# (see point 4.2.).)
Please send the following SMS command to turn the power
(output) ON after a set number of minutes: #138#1#Minutes#
e.g. #138#1#60#
This will turn the power (output) ON in 60 minutes (1 hour).
Note: Minutes are the parameters to be set and the range is 1-
720. If the minute range is set at 0 the function will be invalid and
the power (output) of Powertxt® will not be changed.
4.5. Controlling the Power (Output) by Time Delay – Power
OFF
Please send the following SMS command to turn the power
(output) OFF after set a number of minutes: #138#0#Minutes#
e.g. #138#0#125#
This will turn the power (output) OFF in 125 minutes (2 hours and
5 minutes).
Controllin the Power (Output) by Temperature
5.1. Setting the Temperature Range Parameters
There are two modes for controlling the power (output) by
temperature, Heating Mode & Cooling Mode. These
parameters have to be set first then you turn the function ON
with another SMS Command (see points 5.2. & 5.3.).
Warning – Do not exceed any voltages as stated in this manual
and only connect to electrically safe and reliable equipment. We
do not recommend you leave a heating/cooling device on for

20 21
long periods unattended.
Note – When the temperature range has been set successfully
the scheduled 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.
Heatin Mode
Heating mode is used when Powertxt® is connected to a
heating device e.g. in winter when the temperature is low and
Powertxt® might be used to turn on a heater to keep the
room/environment warm. When the room/environment
temperature goes below the minimum set value it will turn the
power (output) ON then when the room/environment
temperature reaches the maximum set value it will turn the
power (output) OFF.
Please send the following SMS command to set the temperature
control parameters for heating mode:
#159#0#MinimumTempValue#MaximumTempValue#
e.g. #159#0#10#20#
When the room/environment temperature drops below 10 degrees
centigrade the power (output) will automatically turn ON and when
the room/environment temperature goes above 20 degrees
centigrade the power (output) will automatically turn OFF.
Coolin Mode
Cooling mode is used when Powertxt® is connected to a
cooling device e.g. in summer when the temperature is high and
Powertxt® might be used to turn on an air conditioner to keep
the room/environment cool. When the room/environment
temperature goes above the maximum set value it will turn the
power (output) ON and when the room/environment temperature
reaches the minimum set temperature it will turn the power
(output) OFF.
Please send the following SMS command to set the temperature
control parameters for cooling code:
#159#1#MinimumTempValue#MaximumTempValue#
e.g. #159#1#15#25#
When the room/environment temperature reaches 25 degrees
centigrade the power (output) will automatically turn ON and
when the room/environment temperature drops to 15 degrees
centigrade the power (output) will automatically turn OFF.
5.2. Controlling the Power (Output) by Temperature Range –
ON
Please send the following SMS command to turn the control by
temperature range function ON: #159#1#
5.3. Controlling the Power (Output) by Temperature Range –
OFF
Please send the following SMS command to turn the control by
temperature range function OFF: #159#0#

22 23
SMS Temperature Alert (No Power/Output Chan e)
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.
7.2. Status – General Status
This Powertxt® general status gives you information on the
power, temperature and control functions; Output Status (Power
ON/OFF), Temperature Reading, Temperature Control Function
(ON/OFF), Schedule Control (ON/OFF) and Delay Control
(ON/OFF).
Please send the following SMS command to check the status: #07#

As Powertxt® needs the mobile network
to operate very infrequently messages
can be lost or not delivered
1. The mobile signal strength in the area is
not strong enough for this device to work
2. There is no mains power available in the
area where Powertxt® is located
3. The SIM is not activated or live
4. An incorrect command is being sent
5. The mobile ( SM) network is down in the
area where Powertxt® is located
The command you have entered is not in the
right format or the command does not exist
Solution
1. Check that mains power is available on the required connection
2. Check the device is fully inserted into the mains power socket/supply
1. Check the SIM card is inserted correctly & wipe clean the gold contacts
on the back of the SIM card
2. Check the SIM card is activated and live (making sure no PIN code is
active on the SIM itself)
Note – Occasionally you can get faulty SIM cards, check with your SIM
provider
If Powertxt® has received the message/command then the required action
will have been carried out however the return/reply message may have
been lost or not delivered. In this case please either a) send a status
request command and this will show you the status of Powertxt® and
whether it has actioned your command or b) wait at least 2/3 minutes and
try the command again
1. Try a different mobile network provider or try Powertxt® in a different
location
2. Check that mains power is available on the required connection
3. Check the SIM is activated and live
4. Check the command is correct and try again (refer to the user manual)
5. Check with your operator regarding coverage in that area
