Green leaf has a bolt symbol?

[Keller1]

The green leaf on my Nest Thermostat now has a lightning bolt symbol and I don't know what that means

[MCortada]

I have that too.

The leaf with a lightning icon in the middle will appear if your thermostat has adjusted the temperature due to electricity being "dirty" or priced high at that time of the day. For clarity, I'd recommend contacting your energy company.
