Separate Zwave gateway or hub with MQTT integration to Home Assistant

This post is based on the excellent tutorial found here.

I want to run my Zwave stick from another RPi than my HA installation and want all the data to become available within HA through MQTT.

In short, these are the major steps to take:

1. Ensure you have a running HA & MQTT setup, mine are separate Docker images
2. Check that your Zwave stick is being found on the RPi
3. Install Docker on your RPi
4. Install ZWavejs2MQTT
5. Start your Docker image
6. Configure Zwave
7. Do a discovery and check whether your stick and potentially 1 or more Zwave sensors or actors are being found
8. Configure MQTT (disable the Gateway functionality in this step)
9. Configure the Gateway (enable the functionality again)
10. Check within HA if a new entity for MQTT has been found, with your sensors or actors
