You can set up multiple hubs if you want. There is nothing that stops you from doing so. You can pair the same button to multiple hubs. The button will simply connect to the first hub that it can reach when pressed.
@balucanb The Hub mini has "mini" in its name for a reason. It has a significantly smaller footprint and a completely different software architecture which unfortunately means the hub sdk, as it is currently implemented, cannot run on the Hub mini. If you want to use our hub sdk, simply use the Hub LR instead.
The Philips Hue hub is discovered using mDNS on the local network.
Some debugging tips:
I guess you tried power cycle also the Philips Hue hub?
Try if the Hue hub can be found using our Android and iOS apps, without being connected to a Flic hub. That should help figure out if the problem is with the network connectivity on the Hue hub or the Flic hub.
You can for example use the app Service Browser https://play.google.com/store/apps/details?id=com.druk.servicebrowser to see if the Hue hub can be discovered on the network (look for _hue._tcp).
@Emil I hate bluetooth. It worked fine from another phone, so I removed the hub from my primary phone and re-added it. Still didn't work, so I cycled BT on the primary phone, connected with no problem. sigh Not sure why I didn't try that before. Thanks for the pointer! (Taking logs reminded me how awful BT is)
@Emil How often is the settings UI collectively opened that this traffic could genuinely be a concern? This could be a super lightweight request, even just an http HEAD method to a CDN cached response that includes the version in one of the headers.
But let's say that even this traffic is too much, and you must avoid any network activity on Settings load. As soon as the "Check for New Firmware" button is pressed on the settings page, you could initiate this version check call to get the most recent version number. The next page should tell you either 1) that a new version is available and ready to be installed with an "Install" button (also showing the current version, the new version you will be installing, and a link to the release notes), or 2) that you already have the latest version with a "Back to Settings" button (e.g. "4.2.13 is already the latest version"). If there is a network issue, you could report that here with a "Retry" button.
If you are already checking and automatically updating the firmware every 24 hours, that information should be shown in the interface, too. Maybe an info button next to the "Hub Version" on that settings page that explains this. Ideally you would also show a log of the last N firmware updates, or the timestamp of the most recently installed update and link to its release notes at the very least.
@djay@Emil After several attempts to reset the Hub LR again and stuck even not getting it back/discovered by the Flic App, now it's back. And out of the blue the “Configuration needed - need to pair Flic Hub with your home - wants to access Home-Dialog, showed up again.
I have no idea what caused the problem and no idea what really solved it, other than to try and try and try again for two hours. 😕
