The OpenBlocks IoT series features a fanless, compact, and robust design, equipped with IoT gateway software “FW” that enables non-programming connections with major IoT sensors and devices. Despite its small size, the gateway offers numerous wired interfaces such as Ethernet, MicroUSB, and RS-485, as well as highly expandable wireless options like EnOcean, LTE, and regional BWA. It supports current low and high voltage smart meters and next-generation low voltage and bidirectional high voltage smart meters, making it an ideal product for building IoT solutions related to power consumption.
