I did, but I didn't like the fact that its constant "calls" to the car kept my car awake all of the time. Apparently you're supposed to let the car sleep regularly in order to calibrate the battery. I already share my car info with TeslaFi so sharing it with SmartCharge didn't bother me. I just wish their system worked in a less disruptive way. (If TeslaFi doesn't keep the car awake, why does SmartCharge?)
It's nice to get free money from SmartCharge though.
