Description
A production-ready LoRa sensor network consisting of a Heltec Wireless Stick V3 Gateway and multiple sensor nodes (HT-CT62, HT-RA62, ESP32-S3). The system uses AES-128 encryption for secure communication over 868 MHz LoRa. The nodes measure temperature, humidity and other environmental data, sending it energy-efficiently via deep sleep to the gateway. The gateway forwards data via MQTT to Home Assistant, including auto-discovery for seamless integration.

This is exactly what my "LoRa Sensor Node" package covers — from 349€.
I deliver software only (firmware, configuration, code) — no assembled hardware. The components used are only linked for reference, you buy them yourself. Enclosures on request.
