    Z-wave switch cuts itself on!

    I have a light switch in my garage. At 1:19AM, logs indicated that it had been activated manually to ON (no preceding event noted). The garage is locked and nobody has been in it.

    The light actually was on and had triggered HS events (as it should have).

    Any thoughts on how a light cuts itself on?

      I have the occasional phantom turning things on without any event or action from a user. Its mainly plug in on/off switches. It used to be really bad when I had my system running on a Vera. Once I moved to HS3 it nearly stopped. Now it happens about once a month. I never found the cause.

        This can be down to power fluctuation, as quite a few devices default to on after power restoration, or if you have switches in parallel, cross talk in wiring can be enough to trigger devices - I've had to slightly rewire fibaro dimmers for this very reason.

          Rodents crawling on your switch. I haven't had any problems myself with the Z-wave stuff switching on but my old x-10 system was constantly turning on without cause(bad controller).

            We do have glitches, but using Jon's UPS program I haven't had a glitch reported since the middle of September. Now, power supply to the garage.... hmmmmmmm.... I wonder?

              What type of switch is it? I've had many issues with X10 in the past doing this, and rarely Insteon plug-in modules. Never had a Z-Wave or Insteon wall switch flip itself on or off.

                It is a simple Jasco Z-wave On/Off wall switch.

                  I've had this happen too...I posted about it before and never found an answer. Wake up in the middle of the night to get a glass of water and the fireplace is on...ummmm. Only caught it happening twice in the last 2 years. I'm controlling four garage doors with an Arduino since I have yet to see an Arduino output turn on for no reason. I can't be leaving a garage door open randomly.

                    Something just dawned on me..... could this be interference from the 33 cm band?

                    There seems to be a lot of (mostly obsolete) oddball industrial, networking, medical and scientific stuff, as well as unlicensed primary users. Also, this band is open to amateur radio as a secondary user and it appears to be growing in popularity.

                    Or could it be a harmonic? Or is this a dumb question?

                      Well, I have 2 unknown node devices on my network that the controller never added and don't seem to be z-wave. I've been looking at everything with a plug to see if it transmits anywhere near z-wave to try to account for them. I've never had one act on another though. I'd guess its a long shot that a message would be coherent enough to do something without having been designed to talk z-wave.

                        For something important like a fireplace I'd personally set up a recurring event tied to motion where if no motion is seen for more than xx minutes turn off the fireplace and have that event run every 15 minutes.

                          Very good idea Bill. I haven't got motion sensors in the living room, kitchen, and dining room area yet...but I have about 20-25 DSC motions sensors waiting for me to deploy through the house. Just have to pull the wire...which should be in the next month I'm hoping!
