Ember Mug showing empty when there's still liquid in it?

Drink your coffee faster. Honestly the whole product is a solution looking for a problem.

ok but some of us work from home and need a mug that maintains its temperature at 130 for two hours.
Its not built well but it helps.

To the question of whether the factory reset fixes the problem in the long term: no.
I had the same problem with my mug for a year. Each time I performed the factory reset the problem would last me between 2 and 6 weeks. Black coffee would last it the longest. As soon as I allowed my kid to have a milk drink in the mug the problem would return within a few days. The sensor is not robust against any type of buildup. Its a hardware problem that cannot be solved by software updates.

I cracked open one of my Ember mugs after it died. The small pcb that is at the base of the mug has a sensing trace going up into the wall of the mug. Its capacitive, you can see the pad on the component. Nothing fancy.

so theoretically if someone made a replacement pcb with an array sensor it could be modded to read the level of liquid?

Its theoretically possible however the firmware is locked down so to get the level sensor to work you would have to replace the entire MCU. I dont think it would be worth the effort for one mug though.
