Home Assistant Configs

This is my Home Assistant configuration. This also includes my ESPHome device configurations.

Core Hardware

I run Home Assistant Operating System on a Raspberry Pi 4 (2GB model) with a USB SSD. I also use the Pi PoE hat so I can power cycle the Pi remotely if necessary (via Unifi controller).

• Raspberry Pi 4 Model B (2GB Ram)
• StarTech.com SATA to USB Cable
• Kingston 120GB SATA SSD
  • Note: If starting fresh I might consider a NVMe drive so that there's an easy upgrade path someday when/if there's a Pi with PCIe.
• Z-Wave.Me USB Stick
  • Note: If starting fresh I'd get this GoControl Zigbee + Z-Wave stick so that I could use both Z-Wave and Zigbee.
• Raspberry Pi PoE Hat

Core Software

I run Home Assistant Operating System. Installation is super easy (just use balenaEtcher to flash the OS image to your SSD from your computer) and it supports easy 1-click OS updates in the Home Assistant UI via RAUC.

Integrations

Off-the-shelf stuff I've integrated with:

• Z-Wave (for wall switches, outlets, smoke alarms, door sensors, Yale Assure smart lock)
• Ecobee
• OctoPrint (3d-printer controller)
• Yeelight
• Apple HomeKit (for Siri and easy access from Apple devices)
• Amazon Alexa
• Unifi Controller
• Unifi Gateway (custom component)
• Network UPS Tools (NUT)
• TPLink outlet
• Route53 (for updating my DNS record)

Stuff I've built:

• RTL433 MQTT Temperature Sensors
• ESPHome IR Blaster (controls my sound bar)
• ESPHome Fan Controller (controls an exhaust fan in my basement)
• ESPHome Air Sensor (reads CO2, temperature, humidity, particulates, and TVOCs in the air)
• ESPHome Garage Controller (opens/closes my garage and reports open/closed status)

• Change an LED color on my HomeSeer WD200 light switch when the garage is open
• Set the default dim level for lights to dim at 9pm; set default level to full brightness at 7am
• Push notify when the power goes out (my Pi and network gear have a battery backup)
• Push notify when the smoke alarm is trigerred
• Push notify when a Home Assistant update is available
• Push notify when new firmware for one of my Unifi devices is available
• Push notify when my Unifi Controller has new alerts
