 * Support Victron's Ve.Direct protocol on the same chip (cable based serial interface!). Additional information about Ve.direct can be downloaded from https://www.victronenergy.com/support-and-downloads/technical-information.
 * Dynamically sets the Hoymiles power limited according to the currently used energy in the household. Needs an HTTP JSON based power meter (e.g. Tasmota), an MQTT based power meter like Shelly 3EM or an SDM power meter.
 * Battery support: Read the voltage from Victron MPPT charge controller or from the Hoymiles DC inputs and starts/stops the power producing based on configurable voltage thresholds
