How can the temperature be saved on the bulb when the motion sensor is triggered
In the Rules, you can set a Device Trigger based on the motion sensor, turn the bulb on, and choose the color temperature. Where are you running into problems?
The temperature will not stay set when triggered by the motion sensor, if I turn it on with Alexa voice command it stays at the temperature I set.
Remake the rule (you can’t edit some rule settings after they are made) and make sure you set the temp, don’t skip that part. After you choose “turn on”, the temp and brightness setting should pop up.
