“Been using the app for nearly a month now and it honestly left me speechless!!! I never write reviews for apps but this one was worth every penny, but best part is that it's FREE. I appreciate the frequent updates that come out to improve the app! I love when companies really work on the small details!”

“Exactly what I needed! I've been looking for an app to track my home power usage since I live with roommates and want to track my usage. There are several other apps that do this but all charge fees, this app does it wonderfully and gives lots of other helpful information like the electricity price based on your power bill, and how much you've saved.”
Casey B.
“I have been using this app for about four months now and it is pretty awesome. There is a feature where you can allow the app to manage charges, and additional options that you can select that say the app will only allow when your power grid is using clean electricity and/or when electricity is at the cheapest rate. I would recommend.”

FAQ
We’re here to help!
Is Optiwatt secure? Is my password safe?
Optiwatt never stores your credentials on our servers and your data is 100% safe. When you connect Optiwatt to your EV account using your login credentials, we receive an authorization token that can be used to communicate directly with your vehicle. Optiwatt then stores an encrypted version of that authentication token and discards any sensitive data.
Does Optiwatt keep my car awake?
No. Optiwatt will stop requesting data whenever your car is ready to naturally fall asleep (i.e sitting in your driveway). This ensures your car sleeps during its normal cycle, to avoid causing any additional phantom drain.
How does the charge schedule work?
Optiwatt uses your utility plan and exact electricity rates in order to determine the cheapest possible times to charge. Users who want more control can set their target Ready By time and battery level and Optiwatt will determine the best hours to charge to ensure these targets are met.
What is Optiwatt's Preconditioning?
If you enable Preconditioning for your charge schedule in Optiwatt, Optiwatt will automatically warm the battery pack for your departure to reduce some of the effects of cold weather on your EV.❄️
When the battery has been warmed up, your vehicle will have better regenerative braking, more power available from the motors, and longer range.How does Optiwatt make money?
Our goal is to work with utility companies and reduce peak-load demand by scheduling charges during off-peak hours. This will save utilities money by preventing additional "peaker" power plants from needing to be fired up.
What vehicle makes and models does Optiwatt support?
Optiwatt currently supports all Tesla models, the BMW i3, i3 BEV, i3s, 330e, 530e, 745e xDrive, 740e xDrive, i8, X3 xDrive30e, X5 xDrive40e, and X5 xDrive45e, the Chevrolet Bolt EV, Spark EV, and Volt, the Ford Focus Electric, Mach E, C-MAX Energi Plug-In Hybrid, Escape PHEV, and Fusion Energi Plug-In Hybrid, the Jaguar I-Pace and I-PaceEV400, the VW e-Golf and ID.4, the Audi A7 PHEV, A8 PHEV, Q5 PHEV, e-tron, Q4 e-tron, e-tron GT, the Cadillac CT6 plug-in and ELR, the Chrysler Pacifica Hybrid, the Hyundai Ioniq Plug-In Hybrid, Kona Electric, Sonata Plug-In Hybrid, and Ioniq Electric, the Jeep Wrangler 4xe, the Land Rover Range Rover PHEV and Ranger Rover Sport PHEV, the Lincoln Aviator PHEV and Corsair PHEV, the Nissan Leaf, the Volvo S60 PHEV, S90 PHEV, V60 PHEV, XC60 PHEV, and XC90 PHEV. We add new makes and models on a regular basis, so stay tuned for updates!
Is this different from my vehicle manufacturer’s app?
Yes, Optiwatt's charging schedule provides more control and flexibility. In addition to postponing charging until the cheapest rates begin, it also stops charging as soon as the more expensive rates return. Optiwatt’s charging schedule dynamically adjusts on days where you drive more than normal, to ensure you still have the range you need for the following day.
Do I have to use Optiwatt’s scheduler?
No, all scheduler settings can be disabled upon sign-up or log-in if desired.
Does this work outside of the USA?
Yes, we support all countries and currencies.
How does this save earth?
Utility companies are forced to turn on environmentally unfriendly fossil fuel based power plants during times of peak-demand. Optiwatt will charge your car during off-peak hours when your rates are lowest, therefore shifting peak load and preventing these coal generators from ever being needed.
