In openHAB, set `host` to the address of the pi and the `port` to the port of pigpio (default: 8888).
Note: If you are running Pigpio on same host as openHAB, then set host to **::1**.

Set the number of the pin in `gpioId`.
If you want to invert the value, set `invert` to true.
To prevent incorrect change events, you can adjust the `debouncingTime`.
Using `pullupdown` you can enable pull up or pull down resistor (0 = Off, 1 = Pull Down, 2 = Pull Up).
