### What issue do you have? Please be as thorough and explicit as possible.
I could not get Hoobs to update to 4.1.9, no matter what I tried it simply wouldn't upgrade via CLI or the GUI. In the end I relented and downloaded a new image (4.1.9) and reflashed the PI. All looked good, but I still have the oddest issue which I cant solve. I have just one bridge at the moment, EWELINK. It installs fine, find the two wireless switches no errors, no problems. I add it to HK, normal warnings and then they appear as devices. 40 seconds later, they just disappear from HK. If I restart the bridge, they come back but they come up without assignment in a room and default to the bridges room in HK (where all my bridges sit) again just under a minute, they have gone. The original issue as to why I did all of this was trying to move to 4.1.9 and HB 1.3.5, which has now been solved. This has to be something really simple I am missing. To ensure I wasn't loosing my marbles, I installed the MAC version on my Plex box, and I got exactly the same behavior. 

Now the only thing in all of this is IOS 15.0.2, I had to run them in as my work device requires it but someone tell me, what the hell am I missing. Is this anything to do with the Apple TV as the home hub, do I need to do something? If I add Ring, Nest, Connexoon and Magic, they all stay and work fine!
