what does the link say:
http://homeassistant.local:8123/local/emoji/moon/full_moon.svg - check the file location and folder permissions, the “www” is mapped to “local” and should be public.
Forecast was met.no default, but the Home Assistant or integration code has yet again changed, so it does not work for me either. Check, test and change in http://homeassistant.local:8123/developer-tools/template for what should it be: {{ states.weather.home.attributes }}
I should charge you for one-on-one consultation

I’m not sure it is ok or not but using this code:
is showing the temperature:
“Forecast low” is not that important to me
can you provide a copy of your templates.yaml file with the sensors in. 
Hi
Do you have information of my last post including high latency on the lovelace GUI ?
