I'll be the dissenting voice (shocking, I know). I have a super strong zwave mesh - but I have a device or two that seem to just not get the command every once in a while. Rare, but it happens on occasion. And when it does happen it is quite annoying as it is a prominent device in a prominent location.
As it is very important that message gets there in this case, I send the command 3x with 5s in between.
Here's one of them. 55 neighbors, good RSSI, low PER... You tell me why sometimes the command doesn't "get there"/"take effect". Maybe the device is flaky? Maybe it is dying? Maybe the hub never sent the command? Don't know, I'll look at it someday, but for now I'll repeat the commands - 100% reliable since doing so... So...
