From Sensor to Sandbox: Inside EnergyLab’s Real-Time Data Flow
EnergyLab Sandbox 1: Google Sheet snapshot updated every 2 minutes by EnergyLAB NANO-021, publishing MQTT data on boiler operation and EcoFlow/SolarPV performance.
EnergyLab Sandbox 2: Google Sheet updated every minute by EnergyLAB NANO-022, logging MQTT time series data for 22 variables related to the boiler and EcoFlow/SolarPV systems. The system maintains a 2-day rolling history (2,880 rows), totaling approximately 63,360 individual data points.
