Wisdom helps connect you to Earth and reduce your carbon footprint from electric usage by up to 2/3
Wisdom will glow red when your local grid emissions are high, which means it's time to turn off appliances you don't need. Wisdom will glow green when emissions are low, this is the time to use your dishwasher, washing machine, or other emission-heavy appliances.
Wisdom is supported in most of the U.S, Canada Europe and Australia (see full list here https://www.watttime.org/explorer/). If Wisdom stays grey even after resetting location, location is likely unsupported.
