Baubas Cat Posted January 13, 2020 Share Posted January 13, 2020 I have an iPad wall mounted and connected to a Unifi network router by Ethernet. All my C4 devices plus the iPad are all on the same router. Before upgrading to OS 3 if my internet went down I could still use my iPad to control things. Since updating to OS 3 when my internet goes down I get a can not connect message. Did something in OS 3 change that the app needs to connect remotely now or did something change in some setting somewhere that I need to change? I live in a rural area and losing internet is common so I would like to figure out what is happening. Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 13, 2020 Share Posted January 13, 2020 Initially, needs internet connection to connect to the cloud servers when setting up/adding the app. After the device is linked to your account, it's supposed to connect locally. Are you sure you're not running into the whole system coming to a halt when the internet goes down? That's more common than you think, but can be worked around.

South Africa C4 user Posted January 13, 2020 Share Posted January 13, 2020 There have been a number of cases of something similar being reported (there is another thread on this also). I had the same thing a couple of months ago at my holiday house. My dealer has asked me to test it properly (unplugging my fiber feed) but I have never got round to it and internet is up 99.9% of the times one rarely notices the issue. Hopefully it is a bug and can be fixed... Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 13, 2020 Share Posted January 13, 2020 Easiest workaround is to set your controllers with a static IP. msgreenf 1 Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 13, 2020 Share Posted January 13, 2020 A lot of 3rd party drivers that rely on outside servers can cause some sluggishness too, when internet goes out. Quote Link to comment Share on other sites More sharing options...

Aayush Arya Posted January 14, 2020 Share Posted January 14, 2020 Easiest workaround is to set your controllers with a static IP.Is this recommended in general? We typically assign static IPs to all the devices on the network except for the C4 controller, so that it remains accessible for configuration even if the network switch it's connected to it is plugged into a different router that's assigning a different set of IP addresses.

Aayush Arya Posted January 14, 2020 Share Posted January 14, 2020 Even for the controller, huh? I guess I'll start doing that too then. We already do it for everything else. Thank you. Sent from my SM-G970F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my SM-G970F using Tapatalk This is what I’d recommend. Tech support has said at least director statically assigned. But my systems all get static IPs for control system. This way even if your ISP goes out, router does or whatever, as long as you have these devices plugged into a switch, they will talk with each other. The reasoning for director, I believe, is that when DHCP assigned the loop back address may not be used? But if static, it will? At least that’s the gist I remember.

Sent from my SM-G970F using Tapatalk I personally go for dhcp res I always prefer DHCP res as well since this is generally safer in avoiding IP address conflicts. And then it is easier to change other stuff if you have to, like DNS, subnet mask, etc. Quote Link to comment Share on other sites More sharing options...

zaphod Posted January 14, 2020 Share Posted January 14, 2020 True but I don't believe you can change a C$ controller to use a static IP unless you are a dealer. I like to use the same process for network config for everything on my LAN (or at least use as few variations as possible) and while it is pretty easy to change to a static IP on C4 from your desk, with many other devices you have to click through a bunch of menus on the physical device. Like an Xbox, FireTV, Roku for example. If you are using static IP for those devices then you have to actually make the change on the device which can be more combersome and time consuming.

lippavisual Posted January 14, 2020 Share Posted January 14, 2020 That’s why I said critical devices like the control system. Tvs, media players, Blu-ray’s, etc. can live on DHCP. Disconnect your router from your switches and see what happens. You’ll notice everything goes down externally and internally. Quote Link to comment Share on other sites More sharing options...
lippavisual Posted January 14, 2020 Share Posted January 14, 2020 At least with Mikrotik, I can still have my static devices listed in my DHCP lease table so it still one spot to see everything. msgreenf 1 Quote Link to comment Share on other sites More sharing options...
crshepard7 Posted January 15, 2020 Share Posted January 15, 2020 When OS3 was released, iOS devices (maybe all mobile devices?) would not work with no internet. I never heard whether this issue was resolved. Quote Link to comment Share on other sites More sharing options...
