There are many electronic aids around the house, farm and family.We show devices that make life easier and sometimes even safer.Water detectors like the Luminea XMD-107 are a sensible piece of safety equipment wherever there is a risk of a leak - for example in rooms with washing machines or dishwashers.The Zigbee-compatible adapter consists of a wired sensor and a signaling device that can also be integrated into Amazon Alexa or Apple Homekit environments.It is delivered with a free app, but also works with existing ones such as SmartLife or Tuya.The device reports when the two-year battery capacity is coming to an end.The Luminea XMD-107 is available individually (€14.99), but also as a set of two and three (€28.99 and €42.99 respectively).In order to be in touch with their parents, children, especially those of primary school age, do not need a smartphone right away – the Xplora XGO2 smartwatch for €99, which Tchibo is offering for €89 until the beginning of September, is perfectly adequate.At the push of a button, the kids can call their parents or other predetermined telephone numbers.Even text messaging is possible, and the smart watch includes a 0.3-megapixel webcam and a sensor for counting steps.Thanks to the robust housing and IP67 protection, there is no risk of destroying sensitive electronics.With Tchibo Mobil there is a cheap monthly rate (€4.99).Keeping an eye on your own house via the network - this often fails due to a lack of connection, either to the network or to the power supply.The Hama solar WLAN camera (€149) therefore acts independently: It is powered by its own panel and an integrated battery.The can also be placed somewhere else where it will catch more sunlight than where the camera is located.It either saves the images on an SD card or sends them to a nearby WLAN, from where they can be called up with a smartphone or via Alexa hardware.You can even communicate with the recorded person via microphone and loudspeaker, for example if it is placed at the house entrance.On hot days, not only do we humans need enough liquid, plants should also be watered regularly.To automate this, Eve supplies a controller for the outside water tap.You can access the machine via an app - or you can select a program beforehand, which then automatically takes over the water supply.Up to seven time windows can be set up.The current Eve Aqua is the third revised generation with a new housing and improved valves.It can also be addressed via smart home solutions.The unit price is around €150.One for all, namely all types of floors, that is the motto of the S7 Pro Ultra (approx. €1200) robotic vacuum-mop combo.The top model from the Roborock product series knows exactly where it is thanks to laser environment detection.The Lidar technology (Light Detection and Ranging) comes to his aid here, which also ensures better photos in the Pro iPhones.The cleaning flounder automatically recognizes when it changes from hard floor to be scrubbed to carpet and automatically lifts the wet cleaning unit.This is regularly wrung out in the station so that the S7 actually removes the dirt and not just distributes it.With the smart Vidoora doorbell, you can hear and see immediately who is at the door - without complex installation, just power from a power supply unit.The station costs around €200.It offers an HD camera, a display for the name or icons for the function and a bell button.It sends and receives via WLAN or LAN (€25 extra).It is operated via an app on the smartphone or tablet (Android or iOS), with which the visit can be received.It doesn't matter whether you're at home or on the go.If your smartphone isn't ready: Vidoora can also use Grothe Calima wireless gongs to signal that someone is ringing.Everything you need to know - a look at the most important VDI news articles from the world of technology.Free in your mailbox every Tuesday.
