J’ai trouvé une solution, mais faut optimiser le code.
j’ai créer un sensor template.
- platform: template
sensors:
weather_icon:
friendly_name: 'weather_icon'
value_template: >
{{states('weather.saint_xxxxxxx')}}
entity_picture_template: >
{% set mapper =
{ 'clear night': 'day',
'cloudy': 'cloudy',
'fog': 'cloudy',
'hail': 'rainy-7',
'lightning': 'thunder',
'lightning rainy': 'thunder',
'mostly cloudy': 'cloudy',
'partly cloudy': 'cloudy',
'partlycloudy': 'cloudy-day-3',
'pouring': 'rainy-6',
'rainy': 'rainy-5',
'snowy': 'snowy-6',
'snowy rainy': 'rainy-7',
'sunny': 'day',
'windy': 'cloudy',
'windy variant': 'cloudy-day-3'} %}
{% set state = states('weather.saint_xxxxxx').lower().replace('-',' ') %}
{{ '/local/weather/animated/{}.svg'.format(mapper[state]) }}
J’ai les icones animé en SVG dans le dossier /config/www/weather/animated/
j’ai eu ce message au démarrage:

faut que je rajoute unknown dans les variables, car le temp que l’os boot et ma connexion lente ca met un moment a mettre a jour l’info du capteur 
au final ca donne ca
EDIT:
J’ai modifier le code pour l’erreur du unknown en mettant l’icone weather et le problème est résolu 
Sensor template FiNAL:
- platform: template
sensors:
weather_icon:
friendly_name: 'weather_icon'
value_template: >
{{states('weather.saint_xxxxxxx')}}
entity_picture_template: >
{% set mapper =
{ 'clear night': 'day',
'cloudy': 'cloudy',
'fog': 'cloudy',
'hail': 'rainy-7',
'lightning': 'thunder',
'lightning rainy': 'thunder',
'mostly cloudy': 'cloudy',
'partly cloudy': 'cloudy',
'partlycloudy': 'cloudy-day-3',

'rainy': 'rainy-5',
'snowy': 'snowy-6',
'snowy rainy': 'rainy-7',
'sunny': 'day',
'windy': 'cloudy',

'windy variant': 'cloudy-day-3'} %}
{% set state = states('weather.saint_xxxxxxx').lower().replace('-',' ') %}
{{ '/local/weather/animated/{}.svg'.format(mapper[state]) }}
J’ai fais de même pour le soleil
- platform: template
sensors:
sun_icon:
friendly_name: 'sun_icon'
value_template: >
{{states('sun.sun')}}
entity_picture_template: >
{% set mapper =
{ 'above_horizon': 'day',
'below_horizon': 'night',
'unknown': 'weather'} %}
{% set state = states('sun.sun').lower().replace('-',' ') %}
{{ '/local/weather/animated/{}.svg'.format(mapper[state]) }}
