HydroNode

HydroNode is the companion app for the HydroNode environmental monitoring network, built for people who create and connect their own sensors. Whether you run a hydroponic system, greenhouse, weather station, or simply want to monitor the air in your home office, send your sensor data to HydroNode and get clear, useful insights. YOUR SENSORS, LIVE - See live readings from all your sensors and stations in one dashboard - Explore interactive charts and statistics for every measurement channel - Monitor more than 100 sensor types, including temperature, humidity, CO2, particulate matter and particle counts, VOC, soil moisture, pH, EC, dissolved oxygen, water level, wind, rainfall, UV, solar radiation, power, and more ANOMALY DETECTION - Channels learn their own normal range from their history, drawn as a band on the chart - Set your own target band and get told when a reading leaves it - Published guideline values apply where they exist, for example WHO limits for particulate matter - Findings are tracked as incidents you can follow from first detection through to recovery - Push notifications say what happened in plain words WIDGETS AND LIVE ACTIVITIES - Put a reading, a whole station or your open anomalies on the Home Screen - Follow a sensor live on the Lock Screen and in the Dynamic Island - Tap through straight to the sensor that needs you AIR QUALITY INSIGHTS - Get an air quality score for each sensor - Detect ventilation events - Receive clear recommendations to improve indoor air quality REMOTE DEVICE COMMANDS - Control pumps, valves, relays, and other devices from anywhere - Use command templates - Confirm successful command delivery CONNECT YOUR SENSORS - Send data over HTTPS with HMAC SHA256 signed payloads - Use the official Arduino and ESP32 library, available in the Arduino Library Manager - Connect LoRaWAN devices through Helium, The Things Network, or ChirpStack - Set up sensors with guided instructions and ready to copy credentials SHARE AND EXPLORE - Share sensors with family members or your team - Assign viewer, editor, or admin access - Publish stations anonymously on the public map - Follow public stations that interest you CONNECTED ECOSYSTEM - Use the full web app at hydronode.texhfexlabs.de - Connect Home Assistant through HACS - Discover entities automatically and receive real time updates - Send anomaly events to the Home Assistant event bus - Set everything up in minutes with an API token created in the app - Use the open Arduino and ESP32 library on GitHub PRIVACY FIRST - Hosted in Germany and compliant with GDPR - No ads - No tracking SDKs - No behavioural profiling - Your sensor data belongs to you Free to use.
