Hi everyone, I’m excited to share my recent experience of migrating my Home Assistant (HA) setup from an Raspberry Pi 4 to a more powerful Ubuntu/Docker environment on my existing Plex server. This journey was both challenging and rewarding, and I’d love to walk you through it in case you’re considering a similar migration yourself.### The SetupI had been running HA on a Raspberry Pi 4 for quite some time, but as my home automation needs grew, I realized I needed more processing power and flexibility. My Plex server, which was already running on an Ubuntu machine, seemed like the perfect candidate to host HA as well. Before diving in, I made sure to back up everything. I used HA’s built-in backup utility to save my configuration to Nabu Casa Cloud and also backed up my VM on the Proxmox host. It’s always better to be safe than sorry!### The Migration Process1. Backing Up: I started by creating a full backup of my HA instance. This was crucial because I wanted to ensure that I could restore everything if something went wrong during the migration. 2. Setting Up Docker: I installed Docker on my Ubuntu machine and set up the necessary environment for HA. This involved creating a new docker-compose.yml file and configuring it to include my Zigbee and Z-Wave USB dongles.3. Restoring the Backup: Once Docker was set up, I restored my HA backup. This process was straightforward, but I had to make sure that all my add-ons and integrations were correctly reconfigured.4. Testing: After restoring, I spent a good amount of time testing each integration to ensure everything was working as expected. This included checking my Zigbee devices, Z-Wave network, and all my automations.### Challenges and Solutions- Z-Wave Compatibility: Z-Wave can be finicky with hardware changes. I had to re-pair some of my Z-Wave devices because the migration process disrupted their existing network. Thankfully, the Z-Wave JS integration made this process manageable. - USB Dongle Configuration: I had to ensure that my USB dongles were correctly passed through to the HA Docker container. This involved some trial and error with device permissions and udev rules, but I eventually got it sorted.### Lessons Learned- Backup Early and Often: I can’t emphasize this enough. Having a solid backup strategy saved me from a lot of potential headaches. - Plan for Hardware-Specific Issues: Be prepared for some devices to require reconfiguration or re-pairing after a hardware change.- Take Your Time: Don’t rush the migration. Take it step by step and test each component thoroughly.### Final ThoughtsMigrating HA to a more powerful setup has been a great upgrade for my smart home. The increased processing power has made everything run more smoothly, and having HA and Plex on the same machine has simplified my infrastructure.If you’re considering a similar migration, I’d recommend starting with a thorough backup and taking the time to understand your Docker setup. It’s a bit of work upfront, but the payoff is well worth it.Happy automating!
