Harvy2 - Battery-free LoRaWAN® Current metering sensor
Harvy2 - Battery-free LoRaWAN® Current metering sensor
Harvy2 - Battery-free LoRaWAN Current metering sensor The Harvy2 is a LoRaWAN sensor that measures current and power without batteries or external power. Powered by the conductor's magnetic field (min. 1A), it offers maintenance-free, wireless monitoring. Simply clamp it on, connect up to four current transformers, and get real-time data on your IoT platform. Add a voltage converter for full three-phase power analysis. Features include intelligent event filtering, configurable reporting, and easy web interface setup. Why Harvy2: ·        4 inputs with polarised and strain-relieved plug connections ·        For current transformers up to 500 A (larger currents on request) or deZem voltage converters ·        Metering data: RMS currents, active power*, mains voltage*, power factor*, mains frequency*, etc. ·        Intelligent event filter: metering series (inrush currents, etc.) accurate to the second at a defined maximum rate**.  ·        Self-sufficient and maintenance-free (battery-free)  ·        Data transmission up to several kilometres and through thick house walls via LoRaWAN ·        Compact design ·        Flexible and quick installation without laying cables, e.g. via magnetic holder or top-hat rail adapter ·        Easy configuration and firmware updates via USB-C ·        On-site data visualisation via USB-C and web interface ·        Can be used with the deZem IoT platform and any other platform (JavaScript decoder freely available, e.g. for TTN, Chirp Stack, element iot)

Electricity Meter Module FM432ir FM432ir Fludia
Electricity Meter Module FM432ir FM432ir Fludia
The FM432ir is a professional IoT sensor designed to monitor electricity consumption at 1- or 15-minute intervals (depending on the configuration). It is installed directly on the existing main electricity meter and enables reliable remote reading without any intervention in the existing infrastructure. The system consists of an optical read head for the meter and a separate wireless unit, including batteries.The sensor is specifically designed to read data via the infrared communication port of modern electricity meters using the SML protocol, but also works with traditional Ferraris electromechanical meters. The data is transmitted via LoRaWAN networks, enabling regular recording and analysis of the power curve.The measurement data can either be decoded directly in the defined payload format or processed via a Fludia server and subsequently retrieved via API. Thanks to its simple installation, the sensor is ideal for retrofitting and is particularly suitable for the remote monitoring of small and medium-sized buildings in the field of smart metering and energy analysis.Technical specificationsOptical read head compatible with electronic electricity meters (German mME meters with infrared communication port and SML protocol) and electromechanical electricity meters (conventional meters with a rotating disc)LoRa radio – 868 MHz – LoRaWAN 1.0 protocol1-minute option:- mME meters: data message every 15 minutes, including fifteen consecutive 1-minute readings- Ferraris meters: Data message every 20 minutes, including twenty consecutive 1-minute values15-minute option: Data message every 2 hours, including fifteen consecutive 15-minute valuesData decoding and storage for 3 years included (Fludia data acquisition server)Access to the monitoring dashboard included for 3 years (visualisation of the sensor fleet, monitoring of communication/data quality)Data acquisition API included for 3 yearsAfter the first three years, it is possible to switch to a fully autonomous mode (i.e. bypass the Fludia data acquisition server).Batteries: replaceable 3.6 V lithium batteries- Battery life for mME counters: 3.5 years for the 1-minute option, 8 years for the 15-minute option- Battery life for Ferraris counters: 3.5 years for the 1-minute option, 5 years for the 15-minute optionOptical head dimensions: 46 x 29 x 17 mm / Weight: 18 gBattery compartment dimensions: 94 x 74 x 30 mm / Weight (without batteries): 76 g

Electricity meter module iOKE IMST
Electricity meter module iOKE IMST
Electricity meter module iOKE IMST L868 IDThe ‘iOKE868 LoRaWAN® Smart Metering Kit’ leverages the long range and low power consumption of LoRa® to provide real-time data monitoring of energy consumption and secure connectivity to the LoRaWAN® IoT network. It is compatible with most modern smart meters (compliant with IEC62056-21 and SML messages)   The ‘iOKE868 LoRaWAN® Smart Metering Kit’ can be attached magnetically to the smart meter to read out the infrared interface, extract the desired values and transfer those to the LoRaWAN® network with a period defined by the user.   The external antenna provides a maximum flexibility during installation in difficult RF environments. A user-friendly configuration tool offers an easy way to change the radio, calendar and filter settings. These advantages result in a far more comprehensive and detailed feedback on energy consumption and enables a significant reduction of operational costs.   The product includes the following parts: -iO881A optical reading head -USB-cable for power supply (1.8 m) -antenna (magnetic base) with 2.0 m cable. The ‘iOKE868 LoRaWAN® Smart Metering Kit’ comes without any power supply, please choose between battery-holder and power-supply unit (USB), see accessories, if needed.   Note 1: The configuration can be managed Over-The-Air via LoRa® messages or via wired serial interface (Windows PC tool). Note 2: In certain countries, i.e. Austria, the optical interface might be subject to an encryption according to "Smart Metering Requirements VO 2011". This feature is currently not supported by this product.
