* *baud\_rate* (_Optional_): Serial BAUD rate used to communicate with the
HeatPump. Most systems use the default value of `4800` baud, but some use
`9600`. Default: `4800`
* *rx\_pin* (_Optional_): pin number to use as RX for the specified hardware
UART (ESP32 only - ESP8266 hardware UART's pins aren't configurable).
* *tx\_pin* (_Optional_): pin number to use as TX for the specified hardware
UART (ESP32 only - ESP8266 hardware UART's pins aren't configurable).
* *update\_interval* (_Optional_, range: 0ms to 9000ms): How often this
component polls the heatpump hardware, in milliseconds. Maximum usable value
is 9 seconds due to underlying issues with the HeatPump library. Default: 500ms
