Silicone black ESD conductive mat Connect the ground cord of the mat to a reasonable ground. The screw on an AC outlet, the ground connection on an AC outlet, or a metal water pipe. It isn't enough to just connect to something metal, that is worse than not connecting to anything at all. If you have a metal outlet strip, the metal body should be grounded when it is plugged in. Connect the wrist strap wire to the ground connection on the mat, then put the wrist strap on. Now set your Wink Hub on the mat and you can take it apart and work on it. To solder wires in, you should be using a grounded soldering iron or soldering station.
