I just sold my house with an Elk M1 with ZWave, Wireless, Ethernet, RS-232, eKeypad Pro managing contacts, PIRs, TStats, Leviton Lights and Russound Audio. I am buying new house with a Builder installed GE Concord4 panel. What options are available to have some of the same functionality as with the M1 system? I would like integration with a hub to manage Zwave lights, tstats, remote access, etc.
