i recently purchased the FGK101, and have been mucking with it for ages like most of you. It took me a while to get in included. In the end i came across a youtube video that showed to hold down the back TMP switch, then press the internal tmp switch more than 3 times and the led will change from pulsing quickly, to slowly, which shows inclusion. This worked first time for me. Without the temp sensor, it comes up as one device in vera on 622 public beta, a motion sensor.
My biggest issue however, was that it would not detect the magnet. I was sure the unit was faulty. So to eliminate the whole unit and zwave communication as a possible fault, i hooked up a momentary switch to the IN connectors. when i push the button i can see the state switch from triggered, to not triggered. So this proves the unit is fine, the zwave communication is fine, but it must be the reed sensor. So i took a closer look.
I got out my multimeter, and as soon as 1 probe touched the side of the sensor closest to the battery, the led flashed and vera changed state, i removed the multimeter, and it changed back. so next, i put the magnet next to the module, no change again, touched it with the multimeter probe and bang, the state changed, this time however, the sensor didnt change back when i removed the probe, the magnet was holding it in place. i moved the magnet away and the state changed.
So either the magnet wasnt strong enough to close the switch, or the points were to far away inside of the sensor. but after giving it a helping hand the switch closed and stayed closed.
so i figured, the points in the switch are so small, i must be able to bring them closer. so with a real small screw driver, and a magnifying headband, i gave the right side of the switch a gentle push to attempt to slightly bend the wire that little bit closer so the magnet can do it on its own. And it worked.
Now its important that you dont push the wire too much, because if you do, the switch will be constantly closed and you cant even use it as a binary switch, so be real careful, you have been warned.
Do so at your own risk, but like i said, this worked for me.
Now whether installing it in the garage, and all that constant movement will revert the switch to the way it was is anyones guess, but for now, its working as intended.
I hope this helps someone. Report back your findings
Cheers
