## What is Smart4house?

Our application is used to display the status of various sensors of the series Smart4house, In this time (Water leak detector, Binary sensor, Temperature sensor and Wifi relay). 

For using this app properly You have to own this Smart4house device!

Water leak detector
Guard against condensation, drips, leaks, and flooding.  Protect against potential mold and damage.  The Smart4House Water Leak Detector alerts you before a disaster happens. 

Binary sensor
The binary sensor provides convenient state monitoring.

Temperature sensor
The S4H-TM-xx temperature sensor is fitted with an internal and external probe and with a 2m long cable. The sensor can be used as a simple temperature probe or as a thermostat with two adjustable temperature limits. Information about temperature is sent from the sensor to the cloud via Wi-Fi and the home AP at 15-min, 30-min, 1-hour, 2-hour or 4-hour intervals. In the thermostat mode, notifications are sent outside of the selected time intervals when the temperature falls below or exceeds the preset limit. Information on the cloud is sent to your smartphone, where you can display it using the Smart4house application as a numeric value or in the form of a diagram. You can use your smartphone to set or change the display mode, message sending intervals or monitored temperature limits. The measuring range of the internal probe is from 0 to +50°C, and the external sensor range is from -30 to +50°C.

Wifi relay
WiFi relay is designed for remote control of one or two independent devices equipped with potential free contacts. The module includes two relay's contact outputs which are controlled through the Smart4house application in your smartphone or tablet. Requirements for the switching on and off for each output are transmitted from your smartphone/ tablet on "Cloud" and through the AP - Access Point and WiFi network 802.11b/g/n subsequently to the relay. The same path is used by the WiFi relay for sending information about implementation of the requirement. WiFi relay is equipped with a pair of relays outputs with switching contacts. The status of relays outputs is indicated by LED diode light. The relay outputs either may be operated in the on/off mode, or the switching pulse can be generate with duration of 1 second. The transmitted information is secured by encryption.
Application area:
Remote control of entrance and garage gates, outdoor lighting control, remote switching of various heating or cooling modes, remote control of pumps
- for iOS8 or later versions of iOS: added Geofence function to Relay device (controlling relay states by geo location)

## Key features
