I’m not sure when it became available, but I see that this is now in the Wyze Shop in silver. In fact, as I write this, the Web site shows that this color is the only one in stock.
Maybe it’s been available in that color for a while, but I mention it because of today’s announcement about Bulb Cam and how the announcement video shows some of those in black, but I don’t see that as an option for order on the product page. Maybe that’s another situation where a second color will become available at a later date.
