No, ideally they shouldn’t matter @hilljon86,
The only thing that should matter really is that it isn’t already paired of course, and distance. But you’ve already mentioned that you tried once when you were close, so that should be a problem. The general rule of thumb is that you need to be 15’ from the hub when first pairing. After that the device can be further away, but for the initial pairing, closer is better. Personally, I’ve had been able to do it from a further distance sometimes, but it’s a lot more temperamental.
Sometimes it takes a while… I’ve had it before with some devices where I starting the pairing process on my phone and sat for 5 minutes pushing the button on the outlet trying to get it to work with no luck. So I exit out, restart the pairing process and bam… it instantly comes on. Sometimes I’ve had it where I push and push and pushed the button on the outlet and got nothing… so in frustration I put down my phone, walked over to the hub to make sure it was plugged in and working, then returned only to find it pair while I was away.
