The debug does not log outside of nodered is this just for testing?
If you set one of the entities to an current state node, do not set a value in the is section. Just leave it blank. The state/variable (temp or hum) will be in the payload position.
The format to pass the state/variable (temp or hum) will depend on where it will be used. Home assistant nodes it can be passed as {{payload}} .
