Features
Everything WattVise does, for you who charge at home, for residents of a housing association and for its board. How each choice works is under Help.
For you who charge at home
AutoCharge: automatic start
Plug in and leave it: WattVise starts the charging by itself, and pauses and resumes it by price, your plan and your car. No app to open, no button to press.
Smart plan
Reads the car's battery level and, at its measured average charging speed, charges in the cheapest quarters before you leave, ready on time.
Eco charging
Or simply: charge only when the price is low, or low or normal.
Only your car
Starts only when it's your car at the charger, by its position, when it was plugged in or its charging tag.
Prices as you pay them
Spot with your markup and VAT, time-of-use grid fees and power fee, or a fixed price, also by time of day.
Solar surplus
Turned on, the car always charges on what your panels give over, whatever the price or plan: sent from Home Assistant or your own script.
Notifications
Tomorrow's cheapest hours, done charging, not ready in time, a charger offline, a price alert: by ntfy or on your phone.
Statistics
Cost, savings by timing and CO₂ per car, RFID tag and month, every session's charging curve, CSV and a monthly report.
Driving log
Trips with a map and the route, distance and kWh/100 km, as CSV; on for a new car, off with a tick.
Which car tonight
With more cars than chargers: which to plug in tonight.
Your household
Share a charger with the household: they start and pause, the prices stay yours.
Power at home
The house's load from Tibber Pulse, HomeWizard or Shelly beside the charging.
API and Home Assistant
Status, start and pause with a personal token, documented with Swagger.
For residents of a housing association
AutoCharge on the association's charger
Add the association's charger and your car to your own WattVise account (not through the association): it starts the charging when it's your car that's plugged in, and the association's rule decides when it may charge. Your car stays yours: the board never sees it.
Cheap without doing anything
Plug in as usual: the association's chargers charge in the cheap hours.
Low battery? Charge now
If the board allows it: under your car's own level it charges at once, whatever the rule, up to the board's ceiling.
On the association's sun
If the association has solar panels, your car charges on their surplus whatever the price.
Your own smart plan
If the board allows it: your car's battery level and departure decide, within the association's hours.
Parking queues
Join a queue or a swap queue yourself, see your number, and answer an offer in the app.
News from the board
The association's news page, with a notification when something is posted.
What charging costs
The board's own words on the price and how it's paid; share your kWh for the bill if it bills from the app.
Private
The board never sees your car, your RFID tags or who charged.
For the board
Every charger in one place
Free, charging or offline, with an alert when one goes offline.
Smart charging
One rule for every charger, by price or before a time, and at most so many cars at once to keep the power fee down.
Load balancing
Follows the main fuse with a meter: Perific, Shelly, Tibber, HomeWizard, Easee Equalizer, Zaptec Sense or your own.
Solar panels
With the association's panels: as many cars charge on the surplus as it feeds, whatever the rule and the price.
Statistics
Energy, the average price per kWh, CO₂, what timing saved, each charger's occupancy and the result per month and year.
Billing
kWh and cost per member at the association's price, also by time of day, as CSV and in a monthly report.
Members and apartments
Invite links tied to an apartment, a register with addresses and fields of your own.
Parking register
Areas, places, queues and offers, and a list of what to sort out to keep the queues current.
News and mail
A news page you turn on, and mail to members from the association's own address.
