I have the same stuck motion issue with Bosch PIR/Tritech sensors. They are EXCELLENT for the money but 1. take a bunch of batteries at a time and 2. stick on motion, which I filter thru a Webcore simulated motion sensor. If the actual stays on for a continuous minute then turn the simulated off until the actual turns off. Bosch Security PIR Pet Immune Motion Sensor $12 w/free shipping
Fibaro universal - very interesting - never used it, seems like a good value.
In general I expect the latency is due to the cloud not the sensor. Maybe the sensor can be relocated to turn on the light before you get there.
