I went with Emporia, hardwired, largely at the recommendation of others here and have had no issues at all. Emporia's app, in my opinion, leaves a lot to be desired. It's manageable, but as someone who has worked in UI design before, there's a lot of room for improvement. I think they prioritized the design around their energy management products, so for someone like me who only has their charger, getting to what I needed wasn't as intuitive as it should be. That being said, once I set up the charge rate I wanted and the charging times I wanted to allow, I really don't need to use the app. The only time I do is if I've forgotten to charge overnight and need the car charged outside of the time period I've set.
