I made my own motion sensor out of a PIR wired up to a ST shield with a bit of code. The motion sensor has a built in ‘activity’ light. I have verified that the microcontroller sees its pin go high very close to when this light turns on, and immediately sends a zigbee message to the hub. So, I configured this new ThingMotion sensor to turn on a light.
It takes several SECONDS from after the motion sensor’s ight goes on to when the ST controlled light turns on.
There is some serious lag in this system somewhere, and I’m pretty sure it’s not in the mesh network. Anyone have any luck speeding things up? I’m concerned I’m going to need to abandon ST in favor of a ‘do it myself’ solution, which I was trying to avoid, if I can’t get the responsiveness to something reasonable (i.e. below 500msec).
