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, […]
