Democratization of VPD

Features & Capabilities

Vapor Pressure Deficit (VPD) chart and calculator for controlled environment horticulture (grow tent, greenhouse). Automated with sensor integration.

The app calculates VPD using air temperature, relative humidity, and canopy temperature. View real-time VPD values on an interactive chart. Connect sensors for automated readings or manually input data via intuitive sliders and text inputs.

Key features: • Interactive VPD chart with manual input • Default crop types • Organize charts by assigning them to different zones • Display spots that share the same VPD value • Zoom in and out of the VPD chart with a two-finger pinch and drag to pan around • VPD Target - long-press the chart to set a target VPD value • Dew point area visualization • Grow Timeline • Sync sensor historical data by importing it from sensor's app, or via cloud APIs • Explore sensor history by panning and zooming

Supported bluetooth devices: • SensorPush: HT1, HT.w, HT.xw • Govee: H5051, H5072, H5074, H5075, H5100, H5101, H5102, H5103, H5104, H5105, H5174, H5177, H5179 • SwitchBot: Meter, Plus, Indoor Outdoor • Ruuvi: RuuviTag and RuuviTag Pro • Inkbird: IBS-TH1, IBS-TH1 Plus, IBS-TH2, IBS-TH2 Plus • ThermoPro: TP351, TP357, TP358, TP359 • VIVOSUN AeroLab THB1S • Shelly BLU H&T • Xiaomi Mijia 2 (LYWSD03MMC) (original and pvvx firmware)

Supported devices with API connectivity: • Govee • Pulse • UbiBot • Ecowitt • Tuya

Educational benefits: • Interactive Learning: Explore the dynamics of VPD based on changes in temperature and relative humidity by manipulating input sliders and animating the chart • Canopy - Air Temperature Link: Easily visualize and set values by linking canopy temperature to air temperature • Chart Bands Control: Toggle chart bands on/off (dew, under transpiration, prop, veg, flower, over transpiration) for a comprehensive understanding

Included: 1 chart with manual input and grow timeline, device data sync & explore, default crops VPD Chart Plus subscription unlocks: • Unlimited charts • Automated VPD calculation by using sensors as the input data source • Background monitoring and Alerts (temperature, RH, VPD) • VPD history timeline, available on sensor-driven VPD charts • Custom crops

This is such a great little app with updates that provide useful improvements with a simple elegant layout to track VPD in realtime. I track over eight G hydrometers at times and it reads sensors simultaneously no problems. Great work, thank you!

Just a suggestion for the developers, add support for WiFi hygrometers, such as ones from the brand Govee and whatnot. I had no issues connecting to my bluetooth Govee hygrometers, but the WiFi version is unavailable

What was once a very reliable tool has now become a cash grab. To use Bluetooth sensors, (which was free before today) to check temperatures now, is no longer free. Thanks for memories
