systemd service for Home Assistant

systemd notifier

Adds device to integrate with systemd service, notifying both watchdog and startup. My home assistant installation froze more than one time, so I added the watchdog to kick the service if it does.

Setup Process

1. Install using HACS or manually copy the files
2. Add sdnotify to your configuration.yaml
3. Update systemd config
4. Restart Home Assistant

Step 1: Installation

Installation with Home Assistant Community Store (HACS)

For easy updates whenever a new version is released, use the Home Assistant Community Store (HACS) and add the following Integration in the Settings tab:

brianegge/home-assistant-sdnotify

Step 2: Add sensor to Home Assistant's Configuration

Now that that installation and authentication are done, all that is left is to add the binary sensor to your configuration.yaml.

The minimum required configuration:

binary_sensor:
    - platform: sdnotify

Step 3: Update systemd config

Your systemd config should already exist in a file like /etc/systemd/system/homeassistant.service. Add Type,WATCHDOG_USEC,WatchdogSec,Restart=, and RestartSec to your config.

[Unit]
Description=Home Assistant
After=network-online.target

[Service]
Type=notify
Environment=WATCHDOG_USEC=5000000
User=homeassistant
WorkingDirectory=/home/homeassistant/.homeassistant
ExecStart=/srv/homeassistant/bin/hass -c "/home/homeassistant/.homeassistant"
WatchdogSec=20

RestartSec=10

[Install]

Lastly, reload systemd

Step 4: Restart and Test
