As far as I know, its the only app for iOS that works with Envisalink and Honeywell/Ademco Vista alarm panels. And yes it works on my Vista. I use it over VPN and that works too. Gives me the basic functionality I need.
Now the issues to be finished are few, so perhaps it wouldnt take much to get this perfect.
1. When typing in zone names, space bar hits dont appear until the next letter is hit.
2. Unused Zones should auto hide or have option for auto hide. (I will add a Half Star when this is fixed)
3. Zone bypass not possible. I like to sleep with a window open and just bypass it. The app should allow me to select the zone and bypass it. Or give me a keypad entry option, so I can also do things like turn chime on or off. Or use the keypad to let me arm with Night Stay. (I will add a Star when this is fixed)
4. The way it displays the status page and partitions is not right. I have 2 partitions so the zone list should only list the zones in that partition. For example, when I look at Partition 2 and it tells me it is "Not Ready", I see all 64 zones and I have to remember which 5 zones are in partition 2. (I will add a Star when this is fixed)
5. App needs lock screen alerts, ideally on selectable zone changes or alarm notifications. (I will add a Half Star when this is fixed)
