If possible, Charger is the better option since you can charge any EV with it and have the EV be fully asleep rather than being kept awake.

Hi @Jiffj43,

If you have both a compatible car and a compatible EV, you’ll need to make a choice when first registering with Charge Anytime. The EV option involves using a new app powered by Kaluza. The charger option involves using the smart charger app. You can’t toggle between both options. 

As blastoise mentions, registering the charger gives you the option of using more than one EV (you have two Tesla’s I believe), with that charger. Although the vehicle make and model is listed against the smart charger account to help us calculate the charging schedules, based on the listed battery capacity. So you might find that the other EV doesn’t work as well unless they’re the same make and model. 

Thank you and yea both same model of tesla. So hopefully shouldn't be much of an issue.
