Wow, adding even the simplest sensor to a device seems to add a lot of $. Bonavita electric kettles? $38 without temperature, $66 with. amazon.com/Bonavita-BV382

I’d guess the cost increase in bill of materials is probably: 15% extra electronics, 35% any analog sensor, 50% display/UI elements. Modular UI or using an existing digital display if there is one would likely cut cost by 50%

IoT spillover helps, but steam whistle kettles went off patent like 125 yrs ago. Very specific example / solution though.
More interested in adding fractional operation modes to HVAC. This thing where fans and compressors are binary is ridiculous.

Temperature sensor kettles are for off-boiling point though, for stiff like pour over coffee. My kettle has auto shutoff at boiling, so that’s a cheap feature. It’s monitoring/actuating sub-boiling temperatures that’s the desirable leading edge feature

The BIG problem, right now, is that everyone thinks they can be the center of the IoT universe. So do you speak Samsung's protocol, or Google's or Nest's or roll your own?
