Built a weather station with BME280 + UV sensor. Data logging to InfluxDB! Grafana dashboards show trends over time. Compared to commercial weather stations - accuracy is comparable. Adding rain gauge and wind sensor next. Local weather data is surprisingly useful! #weatherstation #sensors #iot #grafana

3D printed enclosure for my sensor node. Fusion 360 + PETG = weather-resistant housing! Designed with proper ventilation for accurate readings. Cable glands for waterproofing. Mounting brackets included. From idea to physical object in a day. 3D printing is essential for makers! #3dprinting #enclosure #maker #fusion360

OTA firmware updates working perfectly. No more USB cables for every change! Implemented dual partition scheme for safe updates. Rollback if new firmware fails to boot. Version tracking in MQTT messages. Deployed updates to 15 devices from my couch. This is how IoT should work! #ota #firmware #esp32 #embedded

Voice control with ESP32 + Alexa. 'Hey Alexa, turn on the garage lights' works perfectly! Using fauxmoESP library to emulate Hue devices. No cloud services or skills needed. Local network latency under 200ms. Voice control without the privacy concerns. Best of both worlds! #alexa #voicecontrol #iot #esp32

ESPHome makes ESP32 programming so easy. YAML configuration instead of C++! Added a new sensor in 5 minutes. OTA updates from Home Assistant. The integration is seamless. Perfect for non-programmers who want smart devices. Converted 3 friends to the ESPHome way! #esphome #esp32 #homeautomation #yaml
