I’m finding the documentation hard to understand, All I want to do is ask alexa “what is the battery percentage” and I want to get the value of a home assistant entity called sensor.battery_state_of_charge back through Alexa.

If anyone has an example node-red flow where they have done something similar please share your setup as I’m a bit lost with this.
