#redfish — Public Fediverse posts

I wanted to add a button to Home Assistant that would turn on my remote server via IPMI. I also did not want to add the ipmitool dependencies to my #HASS container. Since IPMI supports redfish, a simple rest command in home assistant is enough. Add this to your `configuration.yaml`:

```yaml
rest_command:
# Command to turn the server ON
server_power_on:
url: "https://192.168.100.111/redfish/v1/Systems/1/Actions/ComputerSystem.Reset"
method: post
username: "hass"
password: "eX4mP13p455w0Rd"
verify_ssl: false
headers:
Content-Type: "application/json"
payload: '{"ResetType": "On"}'

# Command to gracefully shut down the OS via IPMI (ACPI signal)
server_power_off:
url: "https://192.168.100.111/redfish/v1/Systems/1/Actions/ComputerSystem.Reset"
method: post
username: "hass"
password: "eX4mP13p455w0Rd"
verify_ssl: false
headers:
Content-Type: "application/json"
payload: '{"ResetType": "GracefulShutdown"}'

sensor:
- platform: rest
name: "Server Power State"
resource: "https://192.168.100.111/redfish/v1/Systems/1"
method: GET
username: "hass"
password: "eX4mP13p455w0Rd"
verify_ssl: false
scan_interval: 10 # Checks every 10 seconds
value_template: "{{ value_json.PowerState }}"

template:
- switch:
- name: "Server"
state: "{{ is_state('sensor.server_power_state', 'On') }}"
icon: >-
{% if is_state('sensor.server_power_state', 'On') %}
mdi:server-network
{% else %}
mdi:server-network-off
{% endif %}
turn_on:
action: rest_command.server_power_on
turn_off:
action: rest_command.server_power_off

```

Make sure to create a separate IPMI user with "Operator" privileges (allowed to start/shutdown, but not to modify settings). If you have e.g. #Proxmox on the server, it will receive the IPMI Graceful Shutdown command and cleanly stop all VMs before exiting.

Works great!

Ich hab da mal kurz was aufgeschrieben:

#Checkmk #Redfish #SNMP

Was sind die Vorteile von #Redfish gegenüber hersteller­spezifischem #SNMP oder #IPMI? Und wie funktioniert Redfish im Zusammenspiel mit einem #Checkmk-Monitoring? All das zeigt Checkmk-Profi und Linux-Consultant Robert Sander in einem kurzen How-to in unserem Expertise-Blog.

Alles Wichtige über Checkmk lernen Sie von Robert übrigens regelmäßig in seiner Schulung für Fortgeschrittene an der Heinlein Akademie.
