I have no real complaints about Eero as it has been stable, but I know I am not using all the features as I run in bridge mode.

When I first started looking at mesh wi-fi it was due to a move into a rental house.  My previous townhouse prior was all hardwired with an 2 enterprise access points and a controller handling seamless roaming.     

With the move, I knew I was moving into a house that was not ready for a network and I was not going to spend money wiring it up when I am only going to be renting for ~14 months while I build a new house.   Eero appealed as I could connect the various pockets of wired devices (PoE devices hanging off a managed switchs).   I do have a Sonos setup as well, but have had no issues (knock on wood). Eero is current running in bridged mode as I need multicast packets to flow across the wi-fi onto the wired network.

Now, once the new house is built and wired, everything that can be connected to an ethernet cable will be, including my Sonos setup, which includes whatever wi-fi access point I decide to install.  I know the nuances of Sonos and my managed switches and have that already solved it by adjusting the STP values on the switches to disable the Sonos Wi-fi and using my switch and router as the primary and backup root bridge.  Currently with only 1 Eero hardwired, I do see a lot of spanning tree updates on the network, as I assume the mesh is constantly reconfiguring itself for the best path back to the gateway.

Should I look for an Eero installer to get the PoE kit installed ($300 + labor) and mount 2 Eero's on the ceilings (one on each floor) and hope that I do not run into any problems with the mesh not playing well with both APs hardwired to a managed switch.  Or do I say Eero served me well and look towards a different solution such as Rukus and sell off my Eeros? 

With both Eero access points hardwired, will it ever utilize the mesh between them since the ethernet backhaul should be the fastest and most reliable path.  Can I force Eero not not use the mesh by making the switch ports so low that spanning tree should always prefer the ethernet?

Thanks in advance.
