Afternoon all, I've a Rako system with 32 rooms, 4 RAK links, 3 RAK Stars and 1bridge. I have a problem where one of the RAK links goes 'off line', the other 3 still show On-Line v 0.2.9, but there is no online status on the missing one. None of the room on this RAK Link work, lights are on or off? However, The plates are all On-Line. This is an intermittent problem, but I don't know what triggers the change. Tried powering off the RAK Link, but it makes no difference. Can I reboot the RAK Link? Are there any diagnostics I can try? The system is 2 months old and the reseller is too busy to come out (poor I know, but I have half a house with no light). Rako Technical support weren't interested, all the would do is charge to send an engineer Any help gratefully received Regards, Jez.
