Synology DSM uptime

Hi,

it is possible to add to the synologydsm sensor two new features:

  • last boot
  • uptime

Thank you

This would be quite nice and hopefully not too hard to add

You can use SNMP to achive uptime. I use this code.

# synology.yaml

# Synology NAS
  - platform: synologydsm
    host: 192.168.1.20
    username: !secret secret_nas1_username
    password: !secret secret_nas1_password
    monitored_conditions:
      - cpu_total_load
      - memory_real_usage
      - network_up
      - network_down
      - volume_percentage_used
      - volume_status
      - disk_status
 
 - platform: snmp
    host: 192.168.1.20
    community: public
    name: Synology Uptime
    baseoid: 1.3.6.1.2.1.25.1.1.0
    value_template: >
      {%- set time = value | int // 100 %}
      {%- set minutes = ((time % 3600) // 60) %}
      {%- set minutes = '{}min'.format(minutes) if minutes > 0 else '' %}
      {%- set hours = ((time % 86400) // 3600) %}
      {%- set hours = '{}hr '.format(hours) if hours > 0 else '' %}
      {%- set days = (time // 86400) %}
      {%- set days = '{}d '.format(days) if days > 0 else '' %}
      {{ 'Less than 1 min' if time < 60 else days + hours + minutes }}

Well I can try it but how can I find baseoid for my NAS?

One way ist to use snmpwalk.
I use this string to my NAS.

snmpwalk -v1 -c public 192.168.1.20 | more

For more info, please see this URL https://www.comparitech.com/net-admin/snmpwalk-examples-windows-linux/

If someone still looking for uptime. I enabled last_boot entity which returns timestamp of last boot. Then I created template sensor like that:

sensor:
  - platform: template
    sensors:
      synology_uptime_seconds:
        value_template: "{{(as_timestamp(now()) - as_timestamp(states('sensor.YOUR_NAS_last_boot')))|int }}"
        friendly_name: 'Synology Uptime Seconds'
        icon_template: mdi:clock-outline
        unit_of_measurement: "s"

which will give you uptime in seconds since last boot. :slight_smile:

Hope it helps someone.
