Automating ESPHome Device Updates

In my smart home, I have a few ESPHome gadgets. It can get tiresome after a while to update this each time ESPHome receives an update. Why not just automate this process instead?

In this post, I'll walk you through utilizing a script and automation to let everything operate entirely on its own.

Understanding the Importance of Regular Updates

Let's examine the importance of automation before moving forward. Updates can improve your device's performance by patching security flaws, fixing bugs, and adding new features. These updates are especially significant for ESPHome-running devices since they frequently bring about enhancements to the way your gadgets interact and operate as part of your smart home network.

The Tools: Scripts and Automations in Home Assistant

We will combine an automation in Home Assistant with a script to automate the update procedure. Together, these tools determine which devices require upgrades, which are subsequently carried out automatically.

The script is "ESPHome: Update All Devices"

The backbone of our system is this script. After determining which of your ESPHome devices have been flagged for an update, it proceeds to update them all. A description of its operation is as follows:

  1. Identify Devices: The script first identifies all devices that have an available update using Home Assistant's update entities.
  2. Filter for ESPHome Devices: It then filters these to include only those that are part of the ESPHome integration.
  3. Execute Updates: For each device identified, the script initiates an update and waits for the device to restart (indicated by the device being 'off').
  4. Mode: Set to 'single' to ensure the script runs updates one at a time for each device.

The Automation: "ESPHome Auto-Update"

The script performs the bulk of the work, but this automation makes sure it runs when it should. Let me explain it to you:

  1. Trigger: The automation triggers when any ESPHome device is marked as 'on' for an update.
  2. Action: Once triggered, it calls the script.esphome_update_all_devices, which starts the update process for each device.
  3. Mode: Like the script, it’s set to 'single' to handle updates one by one.

Setting Up the Automation

To set up this automation in your Home Assistant environment, follow these steps:

  1. Access Home Assistant: Log into your Home Assistant dashboard.
  2. Navigate to Configuration. Go to the configuration section and select 'Automations'.
  3. Create New Automation: Use the 'Create Automation' button and input the YAML code for both the script and automation provided above.
  4. Save and Activate: Save the automation and ensure it’s activated.

Effortless Updates for Enhanced Performance

Keeping your ESPHome devices updated with the latest firmware is a simple yet efficient approach to automating your smart home setup and maximizing its functionality and security.

You can have a smarter, safer home without the trouble of manual upgrades thanks to automation, which not only saves time but also adds a layer of consistency and reliability to your system maintenance routines.

Always make a backup of your device configurations before automating any upgrades; you never know when you might need to roll back to a previous version. Now that you have your new automated update system set up, all of your smart home gadgets will be up-to-date and ready to go whenever you need them.
