I have found them too unreliable. Motion happens, blue light in the cylander goes on and then nothing...... walk out of the room and then the light turns on.

I set up ifttt to use one to log when the cat goes in the cat door for a laugh. Most of the time the orange wifi light on the base of it starts flashing and it doesnt work.

Hmm, I've never had any reliability issues with them. Almost immediate response from motion to switching on

Nothing is moving in the room and the stupid motion sensor activates every bloddy ten seconds! So annoying.

Weird, sounds like a faulty unit. Tried the obvious things such as reset and/or firmware upgrade? Mine is working flawlessly.

You don't have the sun shining on it, or a moving shadow?. This can affect cheap motion sensors I have found.
