homeassistant.exceptions.TemplateError: UndefinedError: ‘binary_sensor’ is undefined
The error seems associated with a particular Lovelace View.
It seems you’re referencing a binary_sensor that doesn’t exist. How is that view defined? Does it reference a binary_sensor, and if so, is there a typo, or is there some reason the binary_sensor you expect to exist doesn’t?
Unfortunately, I have spent many hours searching for the elusive reference(s) to the missing binary_sensor in my lovelace files but cannot find it. Meanwhile, insteon, espHome, and zwave devices create “hidden” binary_sensor entities. In the process of deleteing some of the lovelace binary_sensor references (for testing) I have actually created even more errors.
Ah, I see. It was telling you the variablebinary_sensor didn’t exist, and that’s because you didn’t have it quoted (to make it a string.)
I guess I didn’t look closely enough to see it wasn’t complaining about a particular binary_sensor entity ID (e.g., 'binary_sensor.blah_blah'. It would help in the future if you properly format error messages. As you posted them they were very difficult to read which made it easier to overlook stuff like this.)
