Intermittent "Entity not available" error until Device toggled on/off

[ryanmaule]

I have a mini-graph for the temperature of a Sonoff TH10, and intermittently the graph will not load and the error "Entity not available" will display. This can be fixed by toggling the switch on the device on/off, which makes the mini-graph appear. This happens for both of my Sonoff TH10 devices.

Before:

After:

It's strange that it's intermittent, and often the mini-graphs will display perfectly without this toggle.

Here is my mini-graph code:

  - type: custom:mini-graph-card
    entities:
      - sensor.10008d0711_t
    name: Crawl Space
    line_color: var(--accent-color)
    line_width: 8
    font_size: 75
    show:
      labels: false
      extrema: true
    aspect_ratio: 1/3
    animate: true

Here is my switch code:

  - entity: switch.10008d0711
    icon: hass:fire
    name: Heater

Here the same card for 2 sensors: -- unavailable -- not existing

Seems that your sensor is disappearing sometimes. Test with a standard history-graph.
