Ratings and reviews

Started using this app as a part of Comed charging pilot program. I only use about 5-10% of my battery daily, so I don't need to charge my car every day. So it would be nice to have a future to set maximum electricity price that I'm willing to pay, so it will only charge if price drops belowthat level, but if it doesn't, I'm ok not to charge. And when my bettery dropes to the level when I NEED to charge, I will change the charge settings. If that future is added, will change to 5 stars

No option to define charging schedule, only a slider to allow the app to control charging (Which just starts charging right away). Adding on now that I've had a few days to test the app, the smart charging works well in that the car does charge at the correct times based on the lowest cost hours. However, you cannot define/pick any other hours and the app doesn't stop the car from charging when you plug it in (Ex. When you get home from work during peak hours) so you have to manually stop it.

Downloaded this to see if it would give me a more accurate depiction on the cost of my charging habits and how much I'm saving compared to an ICE vehicle. Unfortunately, it was only accurate for my first 2 charges. According to an email I exchanged with them prior to this, they can see my charging numbers are accurate on their side, but for some reason don't pull over to my (user) end. May try again in the future if that can be fixed.

What’s new

The Optiwatt app just leveled up! We gave it a big tune-up behind the scenes to make everything feel faster, smoother, and more reliable.
