Absolute Humidity

Absolute Humidity is a Chrome extension that calculates and displays absolute humidity from temperature and relative humidity data gathered from thermohygrometers. It supports compatible devices from SwitchBot and HomeKit, showing numerical values and visuals so you can gauge comfort at a glance. The app supports both volumetric (g/m3) and gravimetric (g/kg) humidity readings.

Free users can monitor up to 4 devices and will see ads; Absolute Humidity Pro removes these limits and ads and can fetch weather forecasts for any location (cloud-based). Note device range is limited to Bluetooth unless cloud cooperation is configured. The app participates in Amazon Associates program.
