With a Smartphone App. The only true solution to be able to sleep!

How about a smartphone?
With these elements, we have devised a system so you can go to sleep with confidence, the GNS ... Good Night System
Let's see how it works:
First of all, there's a small PC software program to be installed in your observatory control computer; this program knows nothing about astronomy, ASCOM, CCDs, etc., think of it as a dumb assistant. It will just count down, and tell the smartphone app how things are going.
From our CCD control program, or automation software, or whatever we are using, we'll keep the PC software up to date of how things are going, allotting time for each task. This is automatically done by CCD AutoPilot 5, Sequence Generator Pro, and Maxpilote; other programs require the user to work a little bit (detailed instructions for integration with CCDCommander and ACP are included in the user's manual.
Something like this:
... this is a very simple approach; you can go in any detail, updating the GNS for each image, for instance. You just have to calculate how much time each task should at most take, so if it exceeds that time, then something went wrong.
No need to nail down the time for each task - leave a comfortable margin, a few minutes won't hurt.
When the session is started and you go home, or disconnect from the remote PC session, you launch the GNS smartphone application. It will connect to the PC, update the status, and keep polling it until shut down. It will then either stop gracefully after the session finishes, or wake you up if:
- a timeout is not met: covering problems where the PC is alive and well, but some of the astronomy software is not running, preventing the session to continue.
- the communication with the observatory PC is lost for a user selectable number of seconds: this covers Windows problems, physical computer problems, network down, power failures...
- the PC program sends an "immediate alarm": you may choose to be waken up if the observatory refuses to close, or after too many guiding failures, or detection of clouds...
- there's even a watchdog monitoring the whole process: if, for any reason, updates are not received during the watchdog period, an alarm will fire.
What kind of smartphones does it run on?
It is available for iPhone, iPad and iPod touch, and also for Android phones and relatives.
How about tablets?
Well, it will run (confirmed for Apple's iPad; most surely for Android ones), but will probably look a bit ugly.
Does it send SMS, emails, or what?
No SMS, they are not reliable enough; no emails either. Both systems, apart from unreliable, need the observatory PC up and running. The GNS uses sockets (TCP/IP) to constantly communicate with the observatory computer.
We suggest to put the phone in "airplane" mode to avoid receiving calls or unwelcome SMSs.
Is a free version available?
Yes, the GNS Nap Edition. A free version whose purpose is to let you check if everything runs smooth. It will run for 30 minutes before timing out, and the watchdog will not be operative (it is used for the 30 minutes timeout, actually!).
Is it expensive?
I don't think so; it is not as cheap as a the typical smartphone game app, as the market is not, by far, as big, but for about 20€ / 24$, you'll add a nice layer of protection to your astroimaging.
Can I purchase it now?
Yes - for all currently available platforms, see links.
The Windows program and the user's manual are also available.
Couldn't the Windows program gather more information, be more informative?
The key is to keep it simple, so we get rid of (most) problems. It must be reliable. If it were to check the mount position via ASCOM, many other elements and more complexity will make it more prone to fail, hang, or misbehave. This said, we could develop some "satellite" programs for integration with 3rd party devices or software, but then they will run apart from the main GNS module, just updating it in case of need.
Will it work with my current software?
Thanks to the efforts of their authors, it has native support in Maxpilote, CCDAutoPilot and Sequence Generator PRO: for these programs your only work will be to check the relevant option!
• By design, it works "out of the box" with CCDCommander, and with ACP.
• From MaximDL it can be partially used from the "autosave" sessions.
• While official Prism support is added, there's a free (and great) utility written by Niklas Stork.
From the AAG CloudWatcher software it is possible to launch a script in case of changes in the "safe" status - these can be used to update the GNS, too.
Why is this limited to astronomy?
I see uses in my IT job.
Well, it is not limited. Being an avid astronomer, I came up with this idea, but then I realized how useful it would have been in my past career as sysadmin. Contact us and we'll happily help you put it to work in other fields.

Smartphone apps and permissions
Lunatico's smartphone apps (GNS, GNSFree, and the new Dragonfly and the pocket CloudWatcher, and any future ones) do not require nor use any sensitive data or permission. None at all.
Bluetooth apps request location information - this is an android requirement since bluetooth 4.0. We don't want that location information, won't use it, but cannot avoid the system asking for it. And it has to be granted to have bluetooth connectivity.
Not only that, but:
• the apps will only use your Smartphone storage to save its own settings
• they won't access your calls, contacts, identity... nothing at all
• the only data they'll know about you is what you configure in the settings
• ... and even that won't be shared with anyone. Ever.
