Netzero automations enable starting or stopping EV charging. This requires a Tesla vehicle or OCPP-compatible EV charger. See EV Charger Settings for how to configure your Tesla vehicle or charger.
Below are some suggested automations for EV charging:
When electricity price is below $0.20, start charging.
When electricity price is at or above $0.20, stop charging.
When Powerwall is charged up to 100%: Start vehicle charging.
Charging based on a schedule is also possible, but most EV chargers and EVs already support this feature.
Since Tesla recently started charging for waking up the car or issuing commands, the automations are limited to 5 per user in a 24 hour period. This limit is across all start and stop automations. Once the allotted automations are exceeded, they will fail until enough time has passed.
There are no limits for charging with an OCPP-compatible EV charger. Note that Tesla Wall Connector is not OCPP-compatible.
EV charging can only start if the vehicle is plugged in and ready to be charged. Similarly, the vehicle has to be actively charging for a stop automation to succeed.
