How can I measure light using the GreenCast Connect app and Spiio soil sensor?

Measure general sun intensity and sun hours on any plan using GreenCast Connect app widgets. For detailed, site-specific light data in Lux or footcandles, you can utilize the Spiio soil sensor available with a Pro plan. To ensure accuracy, the sensor must be installed vertically with the top exposed and clear of debris. For full installation details, please see this article.
