I have a combined sensor that shows the lowest gas price in the stations I am close enough to. When any of them go below a certain level my Aeotec siren will chime a ship’s bell sound (because the gas is for my boat, I drive an electric car! 
) and send me a mail notification. But I would like both that mail and the markdown card I have made to tell me what gas station triggered the notification. So is it possible to tell from a combined sensor which of the combining sensors that is the lowest price and triggered the notification?
Should be possible by adding an attribute to the sensor if it is a template sensor. Share the sensor config.
Thanks for answering! It’s not a template sensor. At least I don’t think so, I haven’t been able to find any templates it uses, I don’t think helpers can be edited in YAML, but I may of course be totally wrong.
Edit: If you know code that can put into the mail what’s the lowest of all the Bensinpriser labeled entities, that would of course work out to the same.
