New to this group....

 Can I get 2 sets of the Deco M5 and have them work together? Total of 6 units. I have the eero system now and I really don't want to spend another $500 when I can get 6 of this units for the price of one...

If it is possible to get 2 systems to work together, Can I hardwired all of the decos to a switch and back to my modem? Do they have to be daisy chain?  Whats the best way to do it?

Thanks in advance!
