Ok, here’s the scenario:
Two motion sensors, #1 and #2. One Hue bulb (colour).
Person walks past #1, Hue turn on/blue for 2 seconds
Person walks past #2, Hue turn on/red for 2 seconds
Seems simple? If the Hue is at white with no movement, it’s fine. Person walks past (slowly), it will go from white to blue (or red), and return to white (or off depending on initial state).
Here’s the problem, if the person moves between #1 and #2 quickly within the 2 second window…
Sensor #1, motion; light blue
Sensor #2, motion; light red
… Problem seems to be that when a new event is triggered while one is already in progress, as it looks at the current light values before setting the new one. So it reverts back to the wrongly noted colour after the event. Instead of reverting back to white it will go from red to blue.
Not sure if anyone else has experienced this or connecting Hue bulbs directly to ST will fix this issue… any suggestions welcome.
