Eufy camera help

i just installed webrtc and tried the script given on the integration. it works well on the 1st day
after that it disappeared on my dashboard. but if i edit dashboard i saw the camera and its working fine then. dont know what to do…its only my 1st week on home assistant and really an average user.

also trying to figure out how to make entity that count all the lights on…seem to find a template but dont know where to put the template. sorry newbie here
