Hi All,

 

Asked support for help but suggestions much appreciated:)

I am a long time owner and, thankfully, to date have had no 'real' issues. My system is quite large with over 70 actual Z-Wave devices and around 300 'total' devices/scenes/VD's etc. My wife and I depend on it for everything from our Gates, Garage, Lighting, Audio/Visual and, most importantly, Alarm System. I have a large home network, with over 50 network devices, run an Asus DSL-AC68U router, custom Pi-Hole DNS server and also a Cujo firewall. So, I'm not 'expecting' to get hacked but I know 'theoretically' things 'could' still get through.

For some reason, yesterday, in the pm the system went haywire. The alarm siren (and many other things around the house) turned on by themselves. I turned everything off and thought it simply a ghost in the machine. Then today, Saturday, it happened again sometime during 9pm GMT(London). It was slightly different this time in that some things didn't turn on that did on Friday afternoon. Again, I turned everything off that should have been off. Then, it went off again (alarm and everything) just after 10pm UK time and more things turned on (it seemed most switches and lights around the house if not all). I turned everything off (with difficulty) and checked the logs and saw that, especially the first time, nothing had actually been turned on (mistake or otherwise) they came on without any reference in the Events panel. Over the years this has happened on the 'very' odd occasion but this was something else, on a much larger scale. 

Then, I rebooted the HC2 (as I noticed it had not been done for 30 days)....and I've not been able to regain access at all, no matter what I tried. I've turned it off/on a couple of times, rebooted etc etc and all I continue to get is it 'looking' like it's going through to Main Admin window and then get 503, continually. I've cleared caches in browsers, tried 3 different browsers, one mac, one pc and all the same. Both my iPhone and iPad will not connect to the admin account at all, continually saying 'trying to connect' after initially looking like it's got through the admin credentials check (it goes from saying 'connecting' to 'trying to reconnect' in line with, I guess, 503). My general web access is fine for the rest of the network. When I restart the HC2 the main three lights come on, as expected and the LAN cable leds are blinking. I've even checked DDNS server and that's up and running fine and I can even see it constantly querying google. So, it is connecting, but I seem unable to access for some reason. The following is an excerpt from PiHole -tail'd logs:
Jul 28 23:59:38 dnsmasq[605]: 438702 192.168.1.78/33867 query[A] www.google.com from 192.168.1.78

I then tried to access from home.fibaro.com with my Fibaro ID and it constantly says that my HC2 is unavailable. That may be because (I believe) I disabled remote access (mainly as I don't need it with VPN etc) but I don't know. It's also showing up as connected via LAN to my router.

So, that's mainly it. I don't know what else to do. I've never tried recovering the unit (never had to) so am unsure a) if that's what I should do b) if that's what I need to do c) whether something else is at play here and finally, d) how to actually do that anyway. As I said, it's clearly connected to the web and clearly connecting to Google etc even though I cannot access it locally. Obviously its more than suspicious that, for the first time in years, it goes mad and then this happens. I know I can't test it any other way as I don't believe there's ssh access.
