I installed the Chargepoint Home Flex and then signed up for Clearview Energy as my electric supplier under their ClearCharge12Plus plan. They reimburse the supply cost of charging my EV between the hours of 11 pm and 6 am each day. That saves me about 11 cents per kWh. You need either the Chargepoint Home Flex or Juicebox smart charger to send data to Clearview Energy for the reimbursement checks.
