I made a Selenium Add-on for Home Assistant

[davida72]

Selenium is a browser that runs in the background, which can be programmatically controlled to navigate a website. A good number of councils in the UK Bin Collection Data project require Selenium to extract bin collection information.

I understand why it's necessary but I've always found it something of a headache to get Selenium running in a container, then adjusting network settings so that Home Assistant can reliably communicate with it. This add-on simplifies the process, running alongside the UK Bin Collection Data integration within Home Assistant and showing up as http://localhost:4444/. Simple!

• Uses Chromium instead of Chrome, because it has a smaller footprint but functions much the same.
• Turned off the password required to view the Selenium session by default.
• Added settings to adjust max_sessions, session_timeout and java_max_memory for lower spec machines.

  Supported Architectures:

  1. amd64 - Intel/AMD x86-64 processors
    - Desktop PCs, laptops, servers
    - Intel NUC, mini PCs
    - Most virtual machines
  2. aarch64 - ARM 64-bit
    - Raspberry Pi 5 ✅
    - Raspberry Pi 4 (recommended) ✅
    - Raspberry Pi 3 (64-bit OS) ✅
    - Other ARM64 single-board computers
  3. armv7 - ARM 32-bit
    - Raspberry Pi 3 (32-bit OS) ✅
    - Raspberry Pi 2 ✅
    - Raspberry Pi Zero 2 W ✅
    - Other ARMv7 devices

I've only tested it on PC hardware so far so if anyone has Home Assistant running other hardware, especially lower spec hardware, then I'd love to hear if it works for you. Feedback welcome.

Hope someone finds this useful!
