core: zwave.network_ready never fires

Home Assistant release with the issue: 0.101.1

Last working Home Assistant release (if known):

Operating environment (Hass.io/Docker/Windows/etc.): Linux

Integration: https://www.home-assistant.io/integrations/zwave/

Description of problem: So https://www.home-assistant.io/integrations/persistent_notification/ has an example on how to create a persistent notification when Z-Wave is starting up and remove it when it’s ready. I noticed that zwave.network_ready never fires. I tried it with:

• restarting Home Assistant
• Manually stopping then starting Z-Wave from the frontend.

Also… zwave.network_start only fires when I manually stop/start from the frontend, and not when restarting HA.

I haven’t tried zwave.network_complete.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

- alias: 'Z-Wave network is starting'
  trigger:
    - platform: event
      event_type: zwave.network_start
  action:
    - service: persistent_notification.create
      data:
        title: "Z-Wave"
        message: "Z-Wave network is starting..."
        notification_id: zwave

- alias: 'Z-Wave network is ready'
  trigger:
    - platform: event
      event_type: zwave.network_ready
  action:
    - service: persistent_notification.dismiss
      data:
        notification_id: zwave
