Anova just announced the planned obsolescence of their original connected immersion cookers. When my partner wanted one for Christmas 2016 it took all of my self-restraint to skip this product in favor of a “dumb” one, but even back then I was skeptical of the longevity of anything using on a proprietary phone app. Good on Anova for staying in business and keeping their products supported for this long, but lots of these devices will be prematurely sent to the landfill because they’ve lost one of their differentiating features.
I’m not all that eco-minded but I dislike this sort of wastefulness.
For Home Assistant users, the Anova BLE protocol has been decoded and implemented in ESPHome.
