Add different prices for charging at night

sacha81 6 years ago updated by lemassykoi 4 years ago 21

In some regions the prices for the electric power is different on the day and the night. It would be very helpful when it's possible to define a day-rate and a night-rate for charging. 

07:00-21:00 (07:00am - 9:00 pm) is 0.27$/kwh

21:00-07:00 (09:00pm - 07:00 pm) is 0.18$/kwh

Updating prices works but after 25 records it reduces the affected records by one each time for remaining to be updated. I can only update 1 record after logging back in then no further updates.

The best option is to be able to set the price bye API call. My prices change every hour


There is a first version of multi rate charging at home located at https://www.teslafi.com/chargePrice.php if anyone wants to test it out.

When your rates change in the future you can use the 'set pricing' feature at the bottom to 'lock in' the pricing on previous charges before adjusting to the new rates.  This is limited to setting 10 charges at one time for now to make sure it is working correctly.

Please let me know of any issues or comments.



In France, we switch from T1 to T2 at 7.30AM and 11.30PM

Would be fantastic if you could add minutes, next to hours.


Hi James! 

Two Things

1 - When clicking new, it clears all my previous entry attempts, so I need to remember to hit save each time. New should also auto-save existing entries in the text box.

2 - Option for Weekend vs. Weekday rates. Possibly evening seasonal rates.

Here's an example of my TOU rate schedule.

Selecting new will now save the existing schedules.

I added days of the week so you can customize further if you want to test it out.  It should work correctly but still needs some testing to be sure.

For now this is as far as I'd like to go.  With seasonal changes you'll need to set the pricing to apply it to existing charges and change the schedules.

We have PG&E that has both tiered rates that increase with monthly usage and time of use rates that depend on time of day and weekday. I changed to time of use that's lowest from midnight to 3PM with two other rates from 3 to midnight. I charge at night but TeslaFi will use the wrong rate if I'm in a different rate period.

Really could use this as well to be as close to real for costs as possible.  Where I am we have 3 different rates depending on the time of day, and even the time of year.


+1 to have peak and off peak rates.

my power company changes rates 4 times a day.

i know it would be a lot of work, but I'm sure many of us would appreciate it if we could somehow enter our power rates for each hour.

I don't think any utility has more than 4 TOU rates in a day (2 of them usually being the same).

I have 7 different rates during a day:

Combine the varying network + energy charges in each window and you end up with 7 distinct per kWh rates during the day. 

This is a second vote for the suggestion by sacha81 and mike9475 to be able to change pricing from a charge point per date range. Our utility bills at higher rates in winter than summer, and it would be nice to reflect this in the charge summary and calendar views.

We have hourly billing here with ComED. That's probably too much to ask but I'd still love a way to set prices during certain periods. When everyone is leaving in the morning or coming home at night the prices are always the highest!

And in my region prices varies based on temperature : one cost if the temperature is over 12 degrees Celsius, and another price if it is under 12 degrees celcius ... 


In my area the rates are different for Winter and Summer but are the same 24 hours. Perhaps add both time of date rates and seasonal rates.

Also I would love to see if you change Pricing from a Chargepoint per Date. So at work they now give the power for free, before it was 0.18 Cents. Maybe they will charge again in the future.


01.01.2018 - 30.06.2018 is 0.18CHF/kwh

01.07.2018 - 31.12.2018 is 0.00CHF/kwh

01.01.2019 - 30.06.2019 is 0.25CHF/kwh


I'd love this, but I need more than just day/night, peak/off-peak. My power provider (ecotricity.co.nz) gives me 7 different power rates during the day, so ideally this would just allow you to specify a range of times and a rate.

I would love to be able to have both peak and off-peak prices in TF.

In addition, I'd love to be able to tag a charge as free.  The reason for that is that some days I work from home and am able to charge my car directly from the solar panels on the house.  It would not work to have it set to a time or day but just a tickbox that allows us to tag a home charge as free would be awesome.  

This feature will become increasingly useful for Tesla owners who have a Powerwall installed at home and therefore perform a lot of their charges using stored solar energy.


+1 for this.  

+10 if you make it so the prices can be downloaded from an external website.

We use https://www.powersmartpricing.org/ which publishes their prices online for each upcoming day.
