I'm having trouble installing a WEMO wall switch. The light I want to use it on is a single on/off switch, not a 3 way switch. When I remove the face plate, the neutral wire is wired to the light switch on its own. It's not connected to the other neutral wires that fit in the multiple light switch housing. I have tried connecting but it does not function. What does it mean when the neutral wire is connected to the light switch itself and not bundled with the other neutral wires?
If all you have is one wire entering the switch, then the power for the switch might come from the light, and you just have a switched hot.
The white wire should be marked with tape to indicate it's not being used as a neutral.
Unfortunately, if this is the case, then you don't have a neutral available at this switch which is necessary for most of these automation switches. If there are other switches in this box it might be possible to re-route the power for this light, but I'd need to know more about where the power is coming from, what else is there, and how the light is connected in the ceiling box to help. Otherwise, the only way to this would be to run a new wire to the switch location -- either a new 14/3 from the light (so you have hot, neutral and switched hot), or a new power feed with 14/2 from the panel.
