Do you want to turn off a few consumers from home or on the road and do not want to spend much money on it? Then you are right here! The presented “intelligent sockets” are all remotely controllable, but switch automatically if necessary. In addition, they measure temperature data or measure current consumption depending on the equipment. For example, there is something for everyone, starting with the owner of a holiday home, who would like to make his vacation appre- cently frost-free, via the administrator, who has to rescue a crashed server by coldstart, to the needy tourist who wants to simulate his presence at home >
AVM FRITZ! DECT 200
The technical requirements are as varied as their possible fields of application. All assistants need a 230 volt power supply and can only be used in indoor areas.
AVM FRITZ! Powerline 546E
The probably smallest user circle in the test is the switch box FRITZ! DECT 200 by router specialist AVM. It only works with routers (as of OS version 5.50) from own home, in which a DECT base station is installed. The buyer logs them in there quickly and easily configures the radio switches via the router interface (Smart Home).
Belkin WeMo Switch
Up to ten of these sockets can be registered in the router. The established DECT standard, with which cordless telephones communicate with their base, is ideally suited for this: It comes with little transmission power, offers high ranges and is surely encrypted.
GSM-One DRH-301
Since all FRITZ! Routers can also be commanded via the Internet via the FRITZ! App, the radio switch can also be accessed remotely. Automatic switching sequences are programmed by the user via the web interface. First, an ordinary weekday timer, which can be easily adjusted by mouse pointer, is integrated. Presence simulations are defined by the user at random or rhythmically.
In the astronomical position, the FRITZ! DECT 200 switches off / off the external lighting at sunrise and sunset. The data required for the calculation of length and latitude is automatically routed from the Internet. Even Google Calendar can be used as a signal generator with registered "On" or "Off" commands.
Smart: your sensors permanently measure the power consumption of the connected consumers. The web interface graphically displays the current performance graph by clicking, and also calculates the average energy demand and the resulting costs over different time intervals (every ten minutes, daily, monthly and yearly)
This allows current squirters to be quickly unmasked. It is precisely the consumption of devices that operate clocked, such as refrigerators, so precisely. Last but not least, the push service provides the owner with information on current consumption and switching operations via e-mail.
The somewhat more expensive FRITZ! Powerline 546E has the same functions as the small DECT pendant in terms of switching, current measurement and mailing - but otherwise it works differently. So she does not need an FRITZ! Box as an opponent, but acts independently in the home network. That is why the 546E also brings its own web interface, through which it can be set up and operated. The user has access to this if he connects the switch socket to the network via one of the data interfaces (LAN, WLAN and Powerline).
The highlight: It works like a universal translator from one to the other format. As a WLAN bridge, for example, the switch socket receives its data via WLAN and forwards it via one of the two LAN sockets or via Powerline. In the opposite direction, of course, this also works (LAN or Powerline bridge). The FRITZ! Powerline 546E supports the usual standards. In the WLAN it is compatible with the 300 MBit / s fast 802.11n standard and via the power line according to the IEEE P1901 standard with 500 Mbps. The LAN sockets operate at a gross data rate of 100Mbps.
Belkin's wireless switch operates exclusively via WLAN. For the WeMo Switch, the accessory specialist has developed its own app that runs on newer Apple devices.
The setup is done quickly: The iPhoner searches the WeMo Switch among the available hotspots and connects to it. There he enters the network name and the key of his own WLAN. If the WeMo user of the app allows remote access, this can also be done over the Internet. In the app menu, the Apple user can create several switch sockets that work independently. For a better overview, he assigns pictures to the switches and defines their names.
In addition to the manual switching on and off, the app offers only time-controlled switching operations. More sophisticated variants are available only with the optional motion detector or by linking the WeMo switch to the web service ifttt.com. According to the logic "if that, then that" can be around 60 services on the web as triggers.
Also interesting is
The WeMo Switch switches when the user sends an e-mail, the exchange rate of his shares falls or the "Weather Channel" sunset reports. Even the switch itself can act as a trigger. If the switch is connected to a coffee machine, it automatically sends the message to the colleagues via Facebook or Twitter when activated: "Coffee is ready."
This teamwork between switch and web service offers countless switching variants. However ifttt.com - in contrast to the app itself - is only available in English. However, a great service.
MankeTech iSocket 706
In the somewhat clunky DRH-301 of GSM-One is a SIM card reader built, it works thus only over the mobile phone network. The customer must therefore first clarify which of the four mobile radio networks can be received at the location.
Notwithstanding this, GSM-One offers a bundle of switch sockets and blau.de SIM card with ten euro starting credits for four euros extra. The socket is controlled via character strings via SMS. The # 160 # 1 # command turns on the alarm for fast temperature fluctuations. The radio switch always acknowledges the commands with short status messages in English. It registers temperature and load changes and informs the user via SMS.
The DRH-301 is programmable: Depending on the setting, the DRH-301 is switched on or under the set temperature or simply by time control. The user can specify a defined number of minutes or a weekday with the exact times for switching off and on. Changes in the power requirement are also registered: the radio plug will notify if the connected load fails. Thanks to a short battery backup, it even sends an SMS even in the event of a power failure.
In order to allow several users to operate the can, the engineers have implanted two user levels: The master account is allowed to change all programming, whereas family users can only switch off the current at the can.
The iSocket switch sockets also works only over the mobile phone network and therefore needs a SIM card, whereby a prepaid card with some credit is completely sufficient. The iSocket is not quite cheap, with its lush equipment mutates the box however to the mini alarm system and switching center. In addition to the switchable socket, it also has a jack socket on the underside for a further potential-free switching contact.
The iSocket 706 is also ideally equipped for sensors: the built-in temperature sensor warns about frost. The user can also dock additional sensors via an additional jack socket. An optional sensor kit with motion sensor and magnetic contact is available at MankeTech for 50 euros. A microphone is also installed. A holiday home owner might be able to tell if everything is right.
A German-language app for iOS and Android systems makes configuration with the iSocket easier. Actually, however, it is only a translation tool: the commands are sent to the iSocket in the form of cryptic SMS commands. Via the mobile network the box always answers by SMS, however in English. The simple status messages, however, should be understood by everyone.
Since each command is individually sent and acknowledged, some SMS messages and thus costs are combined. With an SMS flat rate for your own mobile phone and the prepaid card inserted into the iSocket, however, the expenses can be covered.
