HI,

Using the example trend sensor of https://home-assistant.io/components/binary_sensor.trend/

binary_sensor:
  - platform: trend
    sensors:
      sun_rising:
        entity_id: sun.sun

sensor state:

01
01752×213 20.5 KB

i get the following error in the logs each minute:

40

sun.sun

06766×250 31.9 KB

Is the documentation wrong, or might this be broken in 0.62.x?

Thanks ,
Marius
