I have this card:
- type: grid
columns: 1
square: false
cards:
- type: entity
entity: binary_sensor.meteoalarmeu
attribute: alerts
unit: alerts
footer:
type: picture
image: 'http://api.sat24.com/animated/EU/visual/1/GMT%20Standard%20Time/'
The picture is regularly shown in my browser just after the entity card, but if i go to the home assistant app on my android smartphone the picture is not shown, showing only a blank square…
This happens also after various clearing caches… and also if i use a picture card in place of the footer
Any hints?
