The Data Logger / Data Logging Instrument is used for precise measurement and monitoring of energy consumption in electrical systems, particularly in households, commercial environments, and small industrial applications. It is suitable for analysing circuits and optimising energy consumption in real time.

The Data Logger / Data Logging Instrument operates with two 20 A ring-type current transformers, each covering a current measuring range of up to 20 A per channel. Current measurement is contactless via the current transformers by passing the conductors to be measured through the openings of the transformers. Voltage measurement is carried out via the device supply voltage. Based on the recorded current and voltage values, the device calculates the current power and energy consumption and displays these values clearly. Installation is quick and easy in the control cabinet on the DIN rail.

The recorded measurement data are transmitted by the Data Logger / Data Logging Instrument via WLAN (2.4 GHz) to an app (Tuya / Smart Life) and displayed there in real time. In addition, the data are stored in the app or the associated Tuya system and can be evaluated and exported there as historical consumption values by hour, day, month, or year. The device itself does not store any long-term trend data internally, but transmits the measured values to the app or cloud for storage and analysis. The measured values are updated at regular intervals of approx. 15 seconds.

Thanks to smart home integration, the device can be integrated into existing Tuya systems and monitored remotely. The Data Logger / Data Logging Instrument is suitable for homeowners, electricians, energy consultants, and commercial users who wish to monitor, analyze, and optimize their electricity consumption over the long term.
