evthefuture / smartcharging

Home Assistant AppDaemon app for controlling charging of Tesla vechiles to only charge when the utility rate is cheap during the day or night. Requires Home Assistant, AppDaemon, Nordpool custom integration and the official Home Assistant Tesla integration.

Smart EV Charging

Charge your Electric Vehicle when the utility rate is the lowest

Currently only Tesla is supported.

This AppDaemon app for Home Assistant require a sensor to get the hourly rate. Currently the Nordpool Custom Component is supported. It also requires the Tesla Integration to work.

Quick Example

This is an example configuration that will make sure charging is completed by 07:30 in the morning. You can also enter an entity I'd of an input datetime (time only) entity in order to be able to easily change the time from Lovelace GUI

Please Note: You need to change the entities to match your setup.

smartcharging's Issues

Add filter info when listening for events

When registering event handler add domain and entity_id.

When receiving event, match domain and entity_id from kwargs. Maybe also include pointers to handlers for different services like turn_on and turn_off

Format time left

Make time left formatted as HH;MM or similar

Smart Charging Status Switch - reporting unexpected values.

Switch for Enable/Disable Smartcharging is reporting "Disabled by user" when there is no need to charge and switch is on.

Values are retained even when switch have been toggled.

IMO time slots should be removed when switch -> off. And recalculated when switch changes state to on.
Then we should always end up with a valid state.

The name should also be changed so it's not the same as the sensor. :).

(Or it's just that they are in some states are displaying the same information which makes it a little confusing.)

Listen to changes if by the latest is an entity

If must be charged by is an entity instead of a fixes time, listen to it for changes.

Allow charging when price is below X

Add an option to allow charging as long as the price is below a specified amount

missing ()

File "/config/appdaemon/apps/ev_charge_control/ev_charge_control.py", line 276, in handle_incoming_event self.get_main_log.exception(f"Exception when handling event") AttributeError: 'function' object has no attribute 'exception'

Add function for start_by_the_latest_at

config parameter "start_by_the_latest_at" is not implemented

Minutes not displayed properly in time left

Hour not substrates from minutes when presenting time left

Add array of charge %

An array of charge levels and when it need to be charged to that level

App does not handle when integration is unable to communicate with car.

For some reason car couldn't be woken when charging should begin.

The app reports charging but it never succeed with the command to the car.

Not sure if you can get any status back, or we just need to check it.

Doesn't wait for required price info (tomorrow)

Seems like required prices are not considered

Tomorrow does not yet exist, it still choose these times
