Quick Setup

egnite Querx can be integrated into existing networks without any configuration effort and supports Zeroconf (mDNS, LLMNR) and DHCP.
WPS simplifies integration into WLAN environments, alternatively, mobile devices can be connected directly to Querx WLAN.

Simple Operation via Web Interface

Each Querx operates completely autonomously, no special gateways or software installations are required.
In the integrated web interface, the recorded measured values are available as interactive graphics for web browsers on the PC, tablet or smartphone.

Reliable Data Logging

Querx WLAN THP has integrated sensors for temperature, humidity and air pressure.
The measured values are securely stored in the device every minute for several years. Logging takes place even if the network connection is disrupted and the recorded data is not lost even in the event of a power failure.

The device provides the data via LAN or WLAN and can therefore also be used in locations without a cable network.

Diverse Alerts

Querx WLAN THP will notify when configurable warning and alarm limits for temperature, humidity, air pressure or dew point are breached, when values are rising or falling unusually fast, and when values return to normal.
Notification takes place selectively via email, SNMP trap, FTP transfer, HTTP push, MQTT or Syslog.

Data Export in Various File Formats

The network sensor can export data, making further processing and archiving simple.
The CSV format is suited for spreadsheet software such as Excel. JSON and XML formats support automatic further processing in custom software solutions. Freely configurable data formats also allow flexible adaptation to existing systems such as cloud servers.

The data export can be triggered manually as well as time- or event-controlled.

Suitable for Monitoring Systems

The sensor can be integrated into network management systems such as PRTG, Icinga or Zabbix via SNMP. Modbus/TCP allows the use with SCADA in the industrial sphere. All logged and current data can be accessed from Python, PHP and other programming languages via HTTP.

Long-term Security

If desired, data is transmitted encrypted via HTTPS respectively TLS. Own certificates can be installed for authentication. SNMPv3 is supported for secure network management.

The Querx firmware is continuously improved and adapted to current developments. New versions are put online from time to time. You can determine your currently loaded firmware version and start an update via the web interface.

Efficient Hardware

Even under adverse conditions, Querx functions reliably and even operates at temperatures between -40 °F and +185 °F (-40 °C and +85 °C).

At the same time, Querx WLAN is highly economical. The power consumption is approximately 1 W. Either a free USB port or an external power supply unit is used for power supply.

Accredited Calibration upon Request

Calibration is a vital component of quality control. With an ISO or DAkkS (German accreditation body) certificate, the measurement characteristics of the Querx network sensor can be documented.
