## Raspberry PI - native GPIO support
| v1.0 - BREAKING: Native GPIO support for Raspberry PI has been dropped |
| --- |
The replacement for native GPIO is [node-red-node-pi-gpiod](https://github.com/node-red/node-red-nodes/tree/master/hardware/pigpiod).
The replacement for native GPIO is [node-red-node-pi-gpiod](https://github.com/node-red/node-red-nodes/tree/main/hardware/pigpiod).

Disadvantages of the native GPIO support are:
- Your Docker container needs to be deployed on the same Docker node/host on which you want to control the gpio.

3. Replace all native gpio nodes with `pi gpiod` nodes.
4. Configure `pi gpiod` nodes to connect to `PiGPIOd daemon`. Often the host machine will have an IP 172.17.0.1 port 8888 - but not always. You can use `docker exec -it mynodered ip route show default | awk '/default/ {print $3}'` to check.

**Note**: There is a contributed [gpiod project](https://github.com/corbosman/node-red-gpiod) that runs the gpiod in its own container rather than on the host if required.
