I have an alert list and when I click on the alert it brings up an alert details display. I use the auto-entities card in YAML displays and this works fine. Code below
What I’d like to do is show alert details based on the type of alert. Examples of types are device offline, temperature exceeds limit, network ping fails, voltage out of range. Each of these types has specific information that I’d want to show. I could extract the “type” from the entity_id or put into an attribute.
What I’d really like to do is use lovelace_gen to parse the hash and then !include the right card YAML as I’ve modularized the dashboard config using lovelace_gen to include cards and views. But AFAIK lovelace_gen doesn’t have the hash…
