One of the most frustrating was my anova Sous Vide with bluetooth. It had a fairly useful app that worked well for monitoring temperature and setting temperature until they changed their policy to force users to create an account on their site. Fortunately I can just use the cooker without the app entirely which is much better than what Canary did. I do like my smart lights, but I'm for a good chunk of them I'm buying the ones where the brain is integrated into the switch and the switch defaults to being a dumb switch when it can't find the cloud connection.
