The Things Indoor Gateway Pro: A Managed LoRaWAN Solution with ESP32 and Semtech SX1302

The Things Indoor Gateway Pro with dual external antenna

The Things Industries first introduced the Things Indoor Gateway, an affordable multi-channel LoRaWAN gateway designed for IoT networks in 2019. While low-cost single-channel gateways like Dragino OLG01, priced as low as $83.50, were available, they often struggled with connectivity in shared environments. The Things Indoor Gateway, priced around $111, offered a reliable solution for large-scale IoT deployments. Building on this success, the company has now launched the next-generation Things Indoor Gateway Pro. This managed LoRaWAN gateway is designed for seamless IoT network installation, featuring zero-touch provisioning, full cloud management, and flexible connectivity options including LTE, Ethernet, and Wi-Fi with automated failover. With advanced device management tools such as mTLS, FOTA, and secure boot, the Things Indoor Gateway Pro is a future-ready solution tailored for evolving IoT needs. Previously, we explored a variety of LoRaWAN gateways, including the AgroSense LoRaWAN for high-precision agriculture, the WisGate Soho Pro RAK7267 for greenhouse monitoring, […]

MachineQ MQpower CT battery-less LoRa CT clamp measures up to 250A of current

MachineQ has recently introduced MQpower CT, a self-powered, IoT-enabled, LoRa CT clamp designed to monitor real-time current consumption. This CT clamp can measure both accumulated (Ah) and instantaneous current(A) with loads up to 100A and 250A with 1mA resolution. Additionally, it integrates a LoRa module for communication that gets powered by the induced current in the clamp itself. These features make this device useful for energy management, proactive maintenance, power monitoring, and more. We have covered various WI-Fi CT clamps in the past like the SONOFF POW Ring, the Emporia Vue Gen2 with 16 CT clamps, the ESP32-S2-based “smart power meter”, and more. Feel free to check those out if you are interested in Wi-Fi CT clamps.
