A Tesla solar customer went to pull up their lease agreement in their Tesla account this month and found something other than a contract waiting for them: the Book of Enoch, an ancient apocalyptic text about fallen angels.

Not a scanned copy of their agreement. Not an error page. The full text of a roughly 2,000-year-old religious book, sitting exactly where their legally binding solar lease was supposed to be. Electrek confirmed it.

Tesla has launched Tesla Home, a home energy management platform powered by an AI engine called Opticaster that it says makes “hundreds of decisions” a day about when to store and use electricity to lower your bill.

However, it’s not an entirely new product as Electrek has been reporting on Tesla’s Opticaster for 5 years.
