I have a Zeus 3 for my inside helm station and Zeus 2 for my cockpit
helm station and can use the "Link" app for remote
viewing and control on my iPad and iPhone.
As Dave says above, there are a few things that the "Remote Control" function of the app won't allow, such as Auto-Pilot. I use Czone for digital control of boat electrical
functions and that won't work
either. The message at the top of these sections says "Remote control of this screen is not available for safety
I tested to see what does work and I could work all functions on the chart view remotely, such as set a waypoint, turn radar on/off, measure distance, switch screen views, etc. I can access all the menus and apps, and was able to turn an alarm
on and off.
As cool as it is, I don't use this app on my iphone or ipad because it loses the connection when I go into my aft stateroom (so can't use it while in bed) or in the cockpit.
So when I'm in bed
I leave the stateroom door open and I can see the Zeus 3 from bed
(and read the text with a opera glasses) and use an anchor
watch app on my iphone by my bed to supplement the anchor alarm
on the Zeus.
If anyone has tips for strengthening or extending the wifi signal from the Zeus I love to know.
