Similar idea. I bought this apparently 3 years ago and use it pretty much every week day while I WFH with no complaints. Top number is the temp of the mug, bottom is the target temp(display temps in F or C). Sensor in the back detects if a mug is present. Turns itself off if there isn’t a mug after a bit or after much longer with a mug if you forget. Works with any ceramic mug, the flatter the bottom the better but my mug has the typical raised outer ring and it works fine. Powered from the wall, not usb.
