Still wondering if I can get my past charging data into the app. You presumably have access to the car’s data, would be great to have the past data (just bought the car in march) rather than just since the app install date. Other apps do this.

Trying out the app to keep track of my charging costs. Last night I charged in 1 session from 55% to 80%, but the app said I charged twice; once from 65%-69% and a second time from 74% to 78%. Where’s the rest of it? No way to accurately track my costs if it only sees small parts of my entire charge. Fix this, and you’ve got a good app!

Won’t allow me to upload utility bill. I click on the “here” link and the “contact us” link and nothing happens. Time to delete.

Optiwatt app started charging my Tesla at 5:56 pm during rush hour lol. Instant delete.

Great app with excessive features to fulfill all of your hearts content. I only use the app for my electricity costs, yet it can also be used to allow your Tesla to be chared during off-peak electricity hours in order to help you save money if you have a bill that varies depending on time of day, peak usage, demand, etc. Great app, would definitely reccomend for any Tesla owner. Best of all, it’s completely free to use!

Confused what the value of this app is when it refuses to show me how much I’m being charged to charge my car despite me uploading my utility bill as well as even manually selecting my energy plan.

I really like this app, but there are some customization things that I would have liked to have seen. The first being that it forces you to compare the cost of fuel versus the BMW, but I am more interested in the cost of fuel versus the vehicle I just dumped to buy my Tesla (a Ford F-150). Obviously fuel consumption in the F-150 is higher than a BMW so their comparison isn’t really giving me an accurate fuel savings. Little things like that which would truly polish it out.

The app doesn’t do anything. Charges during peak hours when it says it shouldn’t be

The app is not logging data from the whole charge. It’s only showing me charging between 80% and 86%. Nothing outside that range.
Great onetobewith
Would be an amazing app if you could track charging on more than one location. I have two homes with different power providers. Also my warehouse as well. Almost there.
