How to Downgrade Home Assistant Add-ons: A Step-by-Step Guide

Downgrading an add-on in Home Assistant isn’t just a techie hack; it’s often a necessary step to restore stability or functionality after an upgrade goes haywire. Whether you’ve encountered bugs in the latest version or simply prefer features from an earlier release, being able to downgrade can save you from unnecessary headaches. Here’s how to do it efficiently, along with practical tips for managing your add-ons.

The Bottom Line: Manual Downgrade via Supervisor

The easiest method to downgrade a Home Assistant add-on is through the Supervisor interface. If you’ve just updated an add-on and are facing issues, follow these steps to revert to a previous version. This method is straightforward, but requires you to have specific version numbers handy.

Step-by-Step Guide to Downgrading Home Assistant Add-ons

Prerequisites

Before you start, ensure you have:

1. Home Assistant Installed: Make sure your Home Assistant is up and running.
2. Access to Supervisor: You need to have the Supervisor add-on installed (which comes in the Home Assistant OS).
3. Version History: Know the version number you want to downgrade to.

Steps to Downgrade

1. Access Home Assistant:

   • Open your Home Assistant dashboard by navigating to http://[YOUR_HOME_ASSISTANT_IP]:8123/.

2. Navigate to Supervisor:

   • Click on the “Supervisor” icon on the left sidebar. You need to be in the main dashboard.

3. Go to Add-ons:

   • Click on the “Add-on Store” tab within the Supervisor section. This will list all installed add-ons.

4. Select the Add-on:

   • Find the add-on you want to downgrade and click on it. This reveals information about the add-on.

5. View Versions:

   • Scroll down to the bottom to find the “Version” section. Here, you will see the current version installed, and below it, the “Add-on version history.”

6. Choose Previous Version:

   • Click on the version you wish to downgrade to. If it’s not displayed, you may have to check the add-on’s documentation or repository for available versions.

7. Install the Previous Version:

   • Click on “Install” or “Update”. This will handle the downgrade automatically.

8. Restart Home Assistant:

   • After installation, restart Home Assistant for changes to take effect. This can usually be done in the Supervisor panel.

Example: Downgrading the Node-RED Add-on

If you’re using the Node-RED add-on and encounter performance issues after an update, you can follow the steps outlined above. Let’s say you just upgraded to version 12.0 but found that a previously stable version was 11.5. After performing the steps:

1. You locate Node-RED in the add-ons.
2. You select version 11.5 from the version history.
3. You confirm the installation, and after Home Assistant restarts, you should find improved performance.

Troubleshooting Downgrade Issues

Sometimes, downgrading may not solve the problem or you might encounter new issues. Here are some fixes:

• Rollback Configuration: Restore any configuration files related to the add-on if they were changed during the update.
• Log Files: Check Home Assistant log files for error messages. This can shed light on unresolved issues.
• Community Forums: If you’re stuck, consult the Home Assistant community for advice on similar issues.
