Hopefully this is the correct location for this post. About every 7-10 days, my HE drops offline from my LAN. It still has the green light, but it is not showing up in my router and won't load on my web browser. I'm connected to a dd-wrt router with an ethernet cable and with address reservation. Cycling the power restarts the HE without any issue. I have 26 devices connected (10 WEMO and 16 z-wave). I also have Rebooter restarting the HE every 24 hours.
Reviewing the logs, I did see "No route to host (Host unreachable)" periodically, but not when the HE dropped offline. I'm assuming that it was still communicating with the z-wave devices while offline. If I were patient enough, hopefully it would recover the connection when it runs the Rebooter app at 3 AM.
