Netzero - EV Charging Automation

Introduction

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.

Examples

Below are some suggested automations for EV charging:

• If you are on a dynamic pricing plan, you might want to only charge the EV when grid import prices are low:

  When electricity price is below $0.20, start charging.
  When electricity price is at or above $0.20, stop charging.
  

• You might want to only start charging the EV after the Powerwall is full:

  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.

Notes

• 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.
