hi,
I have had a trial unit for some months now and its good, however it is only on iOS 8.2 and above, so iPhone 4s and above I believe.
as for reliability think we can say its too early to be certain wrt to notifications and its only the Ethernet version available a the moment but its cheaper than a com ip unit.
You can use the new iOS ap and the old app in tandem, however the usual issues are to be expected with the old app.
as the smart com uses two com ports, one for connection via the smart com and one for outgoing as messages it does mean that connecting to the panel will be easier using the app or wintex.
The old app, you need to program old arc details and portforward on com port 2 set as com ip.
You need need the panel to be version4 and flashed up, wrt the ricochet plug, it works well using the recipes, I set the plug to go active on entering a room, the delay between pir activation and plug turning on was minimal, almost instantaneous.
The advantage of the ricochet plug is two fold, runs off mains so no batteries to replace and can be used to extend the network and even if you don't use the plug with the app its pass through so could be left turned on and utilised, or if your lazy you can turn the plug on with the app.
Older versions of ricochet expander, the version of the expander will mean that the soft mesh wont be available for when the ricochet plug is added so if moved it needs to be recomissioned, however on the newer expanders it will do a soft commission process so no need to worry about the mesh being set up.
believe most places have them in stock as of sometime next week and ADI tell me they have some in stock now.
