Peter, the lack of any real input from installers on here has been noted and not just by myself. One point of CG's findings is that serious vulnerabilities can't be patched in some cases so keeping one step ahead of threats isn't going to happen. You may well have been in the industry since Noah but we are in 2015 now and facing a different kind of threat from, in some cases, kids younger than your favourite pair of socks who have more technical knowledge than most, if not all, any old school installer on how these things tick. You talk like a bigger cost option is definitely more secure than a cheaper device but maybe CG has more to come to dispel that belief.Grade 3 security aside who wants their automation equipment being messed with as is happening now with things like central heating being turned up at daft hours by a hacker? Expecting proper secure coding isn't much to ask is it?
