    ## Tesla controlled charge rate based on power sensor  

    Checks every x minutes to find the optimum charging value based on home power usage W.

    Decreases charge rate significantly when a upper or maximum W value is reached by a power sensor.

    Increases charge rate by 1 every x minutes if power sensor is below a lower W value.

    **IMPORTANT => Use at your own risk. Please see the discussions in the Home Assistant community**
