Binary Sensor callback constraint

Is there any way i can use a Binary Sensor as a callback constraint? Cant find any documentation on it

there is no callback constraint for that, but there is a good chance that if you use the input_boolean constraint and give a binary sensor that it would work also, because its also on/off.

if it doesnt work you could use:

if self.get_state(self.args["binary_sensor"]) == "on":

at the start from your callback
