I'm a newbie. I think I'm missing a basic concept. When I use a call service node to turn on or off a light. It doesn't work if I use light as the domain. It only works if I use homeassistant as the domain. What am I doing wrong? ie ![HAdomain](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/2/5/255f70f85be8b333cf53da08da412436d0a9a5ac.png) This works. This doesn't work. ![HAlight domain](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/7/8740fb6c2a0a6474f025c9762e14e1d3ef6d1c74.png) Thanks for your help. Steve ---

You might get an answer w here but you have more chance on the HA forum. Most folk here use node-red without HA. ---
