I have a Red On/Off switch in a 3-way configuration with a dumb 3-way switch powering a single light. It is showing extremely odd behavior but I think I’ve narrowed it way down.
The Inovelli switch will not send power out of the red traveler terminal to the dumb 3-way switch.
If the dumb switch is in the position such that it expects power coming in over the wire connected to the Inovelli Load terminal and then I turn on the light at the Inovelli switch the light will come on.
If I test Load to Ground I see 110Volts as expected.
If I then turn the Inovelli off the light turns off, I no longer see voltage at the Load terminal, but I also don’t see voltage between the Traveler and Ground. This leaves the dumb switch “dead” if you will. There’s no voltage going to it.
I could outline a few other scenarios but I’ll stop for the moment. Just like a normal dumb switch, shouldn’t either the Load or Traveler show voltage at any point in time? Otherwise, how does the dumb side work?
Okay, so I’ve done a lot to troubleshoot this. Here goes (in no particular order):
- I’ve replaced the switch with a new one.
- I replaced that new switch with an even more newer one
- I have a few lying around
- 3 switches all exhibit the same behaviors
- Removed the inovelli switch and replaced it with a dumb switch
- the two dumb 3-ways acted like they should
- proves (maybe?) that the wiring is set up correctly.
- Removed the nodes from my zwave network and re-added
- back when I thought remote control was part of the problem
- in my most recent troubleshooting I don’t even bother pairing the switches
- Open all the electrical boxes on the circuit and draw a diagram of the wiring (see below)
- I thought, hey maybe there’s some weird wiring happening here.
- it seems pretty normal to me - nothing too crazy?
- Removed all 23 devices from my zwave network, reset the controller and repaired everything
- this was possibly overkill and very much not fun
- “healed” the zwave network
- again, when I thought zwave had something to do with this
- signal test (hold config for 5-10 seconds then release)
- they all pass
- results were solid green, or solid green then red
- which I believe means the device isn’t paired)
- Drew a whole diagram of this corner of the house
- again, when I thought the issue was zwave network related
- Made a quick video
- Shocked myself zero times.
- that’s a win, right?
Is it possible the switch detecting a short on the traveler and killing the power to it? If that’s the case how come the circuit works with 2 dumb switches?
Next steps? What else can I test?
