Would there be any problem meshing the xd4 and xt8 systems together? I have a big house and have the node on the xt8 on the complete opposite side of the house from the router. was thinking about getting an xd4 to supplement it but i'm wondering if it might be overkill. would having too many nodes (a router and 4 nodes if i do this) cause any conflict? since they are both AX systems i would assume there would be no issue unless having too many nodes could cause issues?
