Calibrating Querx Sensors
When calibrating a device, its measurements are compared to an exceptionally precise reference device. ISO- or DAkkS-Calibration Querx network sensors are factory calibrated, however, a certificate is not provided. egnite optionally offers ISO- or DAkkS-calibration certificates. Whether or not you require this depends on the way you intend to use Querx. On the one hand, […]
Email from Querx with restrictions
Due to technical limitations of the small Querx, there may be compatibility issues with certain email providers when sending emails in some cases. For maximum compatibility, we recommend using our successor model Querx WLAN, which does not exhibit these limitations.

DAkkS Calibration Certificates for Querx Sensors
Having measurement devices checked in a laboratory accredited by the DAkkS (German Accreditation Body) will assure you that the calibration was conducted in compliance with all current norms and laws and on a level that is internationally comparable. The temperature of a calibration object is measured by the device that is to be calibrated and […]
The Sporadic Glitch
A day in the hard life of a firmware developer 😉 It can occasionally happen that a manufacturer does not test their products carefully enough in all variations, leaving it to the customer to find remaining bugs. This is the banana-principle: The product ripens with the consumer. This is, of course, annoying for the customer, […]
