0.115.1 - Platform systemmonitor does not generate unique IDs. ID last_boot already exists

Configuration
1

Hi All,

Since upgrading to 0.115.x I get this error:

2020-09-19 10:57:43 ERROR (MainThread) [homeassistant.components.sensor] Platform systemmonitor does not generate unique IDs. ID last_boot already exists - ignoring sensor.last_boot

I tried to remove the platform from configuration file, stop HA
remove the ID in core.device_registry restart HA without system monitor.

then add the system monitor again and reboot HA

But get same error back.

How can I solve this? Its not something that brick my system, but would be nice to solve it :slight_smile:

I was having this same issue, turned out the attribute was duplicated in my system monitor config, deleted one instance and problem solved.

Hi guys, i dont seem to have a duplicate line. Any idea what could be causing this for me?

  - platform: systemmonitor
    resources:
      - type: disk_use_percent
        arg: /home
      - type: memory_free
  - platform: systemmonitor
    resources:
      - type: memory_use_percent
        arg: /home
      - type: memory_free
  - platform: systemmonitor
    resources:
      - type: load_1m
        arg: /home
      - type: memory_free
  - platform: systemmonitor
    resources:
      - type: load_15m
        arg: /home
      - type: memory_free
  - platform: systemmonitor

Oh wait, i think i get it. right now they are all duplicates :slight_smile: need to combine them all in one entry…

  - platform: systemmonitor
    resources:
      - type: disk_use_percent
        arg: /home
      - type: memory_use_percent
        arg: /home
      - type: load_1m
        arg: /home
      - type: load_15m
        arg: /home
      - type: processor_use
        arg: /home
      - type: memory_free

right?

I believe you need lines within each also for

Name:
unique_id:

  • and from what I understand, they cannot be combined into one section.

I ended up finding this forum question when doing a search for a related problem I have. I am adding a new command_line entry in my configuration.yaml that I had previously but had removed. I have made sure 100% there are no duplicates within the configuration.yaml where I am adding it. When Home Assistant starts up, only that one command_line sensor does not even load, and there is a message in syslog saying that the unique_id supplied to it was a duplicate. Where can I find the other one? Any ideas?
