# refreshing the template entities in developer tools might create an unwanted results 
# because they all become temporarily unavailable when the template entities are refreshed
# and can result in a SAFE situation in the group sensor. 
# it is therefor advised to create template sensors in the UI (create helpers)
# this will only effect the template sensor you are working on and not all template sensors textual defined
# so use the file ony for cut & paste
