Is it possible to start a flow with the state of ‘show_header_toggle’ (true or false) from type: entities?
I don’t think so because you can’t use it as a part of an automation in Home Assistant. But maybe somebody can help out
show_header_toggle as in in the lovelace card from front end. I doubt it will work, but what is your use case? maybe we can suggest another way if we can understand what are you trying to achieve.
Indeed: I would like to use the binary data from show_header_toggle from the Lovelace front end to start a flow in Node-Red, as you would do with a regular input_boolean
The work-around would be to create a Flow in Node-Red to do the same thing as the toggle does in Lovelace, but that seems too much work / prone for errors
