Found my own answer to this issue.  The EERO although it states to be a "mesh" network and although it creates multiple paths for data (i.e. choosing to go around a block or even wireless vs. wired) it does not fully communicate between nodes to maximize connectivity as many mesh networks will do.

Imagine the scenario where your power goes out and then powers on again (not too hard to imagine) and all your devices shut down.  When the power restores, you EERO network comes back one node at a time.  Each wi-fi device comes on also at different times depending on their boot time (most of mine come on way before the EERO network is ready).  Each wi-fi device when it powers on will try to reattempt to connect to your network and will find the first device available to it.  This may be one of your EERO devices furthest away and it fact it may be all your devices if the other nodes take much longer to come on line (and they sometimes do).  You now can have 30 devices on one node and none on the others.  The EERO does nothing to load balance.  Even worse you may now have a device on the furthest node with the weakest signal creating issues for your device (i.e. poor stream from a camera).

If the EERO can adjust the node when a device moves from one node to another, why can't it adjust for a static device when it sees that it could register on another node based on signal strength? 

Even if EERO did not want to put some intelligence into checking signal strength across the network on some periodic basis, it could at the very least give you a preferred node entry in the device table since you register your devices in the setup in the EERO network manager or a block device at the node level.  This would allow for the user to at least manually assign devices to load balance the network for static devices.

The only work around I found is a time consuming manual one.  You need to start your EERO network, give it time to settle, identify manually look for devices through the EERO app by going into each node and looking at the "Connected devices" and then power off and on any devices that appear to be on the "wrong" node.  This is very time consuming.

Just my 2 cents, remember when you get free advice, you usually get what you paid for!
