Can't include a light switch, does load and line matter?

I wired up a few other Jasco switches with the veralite no problem. I just installed another and cannot get it to “pair” . If the line and load wiring is backwards will that not allow the unit to pair?

Can’t be sure which wires were load and line. Thanks.

I would imagine yes. Swap the wires and try again…

Then you should not be connecting new switches!

A Line wire will always be hot. In most cases, a load wire will only be hot when the switch is connected and turned on. You can determine this with a multimeter or a voltage detector(safer). But, you should always positively identify all wires before connecting anything.

One should not swap wires around without knowing what they are. If you can’t be certain of what you have, get an electrician.

Been doing electric for a while and I know what’s what. But to know (coming from the inside of an outlet box) which black is going to the light and which is the line (with power off) is a guessing game eally. Just thinking though yeah I could while I have it apart use my meter to see which is line :P. It’s just a pain running up and down the stairs to the breaker, but i’ll do it.

Any other definitive answers on this? I am not home until Friday so I can’t try anything, just looking for a consensus.

If this a dimmer switch or on/off relay? If it’s a dimmer without a neutral connection, it doesn’t matter.
If if is a relay, and line and load are swapped, it won’t be getting power (unless it was in the “on” position when you turned the breaker back on, but the moment you click the switch off, it will break the connection and not respond any more).

Adding on to @PurdueGuy’s post. You never stated whether or not the switch works when attempting to manually turn the light on and off. If the switch doesn’t work manually then you may have a bad switch or a wiring problem. See my previous post.

If the switch works manually, but won’t include it has likely already been include in some network or another. Did you try to exclude the switch and then include it? Excluding the switch resets it to factory default and then an include should work.

But if an experienced electrician offers to walk you thru the steps to connect it correctly don’t worry, zwaver will try and belittle him to make himself feel superior. That’s the way a community of users interacts.

Carry on.
