From your logs it seams the import was not successfuly. You miss on sensor key and it is probably because of a bug that was fixed few days ago. You need to remove the sensor from config to be imported again, but i think is more easy to restore the factory configuration by accessing /factory-reset path of the emulator host in any browser.
Tradfri Motion Sensor has a problem and from what i know Deconz did not introduce any workaround. On motion detection it send the last know light state which means the next day when you enter in the room even if is powerful sun outside the lights will still turn on. As workaround i introduce these 4 mods.
internal = use the annoying light sensor
none = always turn on the lights
astral = use the astral library instead on the light sensor
combined = recommended one, use both astral and internal light sensor (light sensor is used only if it was reporting last data in last 15 minutes).
okay, i started all over again because my SDcard of my pi died. And it still does not work. its frustrating.
same result: i can add the sensor and it is detected in the philips hue app as well as in hue essentials but in the philips app the settings of the sensor dont load BUT
in the essentials app i can configure the sensor with the problem that it triggers always like 30sek. zu late and the “test motion” menue does always show “no motion detected” even if the sensor is sitting in front of me.
maybe is the sensor defective?
EDIT: and phoscon tells me 60% battery left even tough i used the sensor only for like 2 wooks only for testing.
EDIT2: Okay, now it seems to work sometimes. looks promising. thank you guys
