When I connect Hue to Nest for the "works with nest" integration it creates all these alarms for each individual hue bulb, on and off all day a different times? And I can turn off the alarms but can't edit the details of them, but that seems like a pain, I have like only 7 bulbs right now but it created like 4 alarms for each for a total of 28 alarms that I have to manually go in and turn off the alarms for?? Seems ridiculous?
Hue has pushed a fix for this issue. Please respond if you are still having issues.

I want to create my own train app for learning.
My opinions:
- some dates and times (for example, Monday, 20 May 12:12 am train is coming).
So I will have many data and I will save it with Core Data.
Also I will create a today extension which will show something like: "next train comes in 7 minutes".
My question is: How can I make the background updates?
The app must check every X minutes and look if some train is coming by date/time.
What's the best way to do that? Is it possible? Or will the iOS core terminate my app in background?
What's with the battery remainig time?
Thanks i will read the documentation,
but i think i must have an Server that sends a notification to the App.
Everything Timer or something like that will terminate by iOS core
How do I stop MetaTrader Terminal 4 offline chart from updating the price on its own?
I want to update the price on my own because of the difference in timezone with my broker. I have checked all the properties and the MQL4 forum. No luck.
For truly offline-charts, there is a way
While regular charts process an independent event-flow, received from MT4-Server, there is a change for retaining your own control over TOHLCV-data records -- including the TimeZone shifts, synthetic Bar(s) additions and other adaptations, as needed.
You may create your own, transformed, TOHLCV-history and import these records via F2 facility, called in MT4 a History Centre.
How to avoid a live-quote-stream updates in MetaTrader Terminal 4
The simplest ever way is not to login to any Trading Server. This will avoid unwanted updates from reaching your local anFxQuoteStreamPROCESSOR.
There used to be a way, how to inject fake QuoteStreamDATA into a local MT4, however this enters a gray, if not black zone, as MetaQuotes, Inc., postulated the Server/Terminal protocol to be a protected IP and any attempt to reverse-engineer they consider an unlawfull violation of their rights and could cause legal consequences, so be carefull on stepping there. Anyway, a doable approach with an explicit risk warning being presented above.
Can't be done. Quotes get fed in from mt4 and get "evented" into the metatrader.
So I'm making an iphone application that needs to scrape a website once everyday.
What I'm going to scrape is a table of upcoming games for that same day for a soccer division. Thats why i need the app to scrape from the same page and same table once everyday to keep the upcoming games updated.
I was referred to import.io but they didn't have something like a schedule re-crawl.
I would love to get some ideas and tips to how i should do this since I'm stuck now.

I played around with the service a while back and was impressed with how easy it way to set up. They have a "free" option so long as the APIs you create are not private.
Oh, and I agree with Paul, screen scraping is not something the iOS client should be doing. Too fragile, and when (not if) something breaks, you will need to go through an Apple review process to fix it.
This doesn't seem like something an app should do, your server should do it (so that the scraping is only performed once), and your clients can retrieve it from your server. That also means you could send out push notifications for important fixtures etc. Maybe that's what you meant, anyway.
If it's on the server you can just setup a scheduler (in Java, for example) to run once every x hours (probably a smaller number than 24 assuming you don't know when the website is to be updated). Then your app can just get the latest list of fixtures from your server on startup, pull-to-refresh, etc. Presumably someone will open your app, look at the fixtures, then come out of your app - so it doesn't seem like you need to cover the case where someone is in your app all day, but if you did you could use NSTimer to run every x minutes after the initial on-startup server call.
I'd like to infrequently open a Twitter streaming connection with TweetStream and listen for new statuses for about an hour.
How should I go about opening the connection, keeping it open for an hour, and then closing it gracefully?
Normally for background processes I would use Resque or Sidekiq, but from my understanding those are for completing tasks as quickly as possible, not chilling and keeping a connection open.
I thought about using a global variable like $twitter_client but that wouldn't horizontally scale.
I also thought about building a second application that runs on one box to handle this functionality, but that seems excessive if it can be integrated into the main app somehow.
To clarify, I have no trouble starting a process, capturing tweets, and using them appropriately. I'm just not sure what I should be starting. A new app? A daemon of some sort?
I've never encountered a problem like this, and am completely lost. Any direction would be much appreciated!
Although not a direct fix, this is what I would look at:
Time
You're working with time, so I'd look at what time-centric processes could be used to induce the connection for an hour
Specifically, I'd look at running a some sort of job on the server, which you could fire at specific times (programmatically if required), to open & close the connection. I only have experience with resque, but as you say, it's probably not up to the job. If I find any better solutions, I'll certainly update the answer
Storage
Once you've connected to TweetStream, you'll want to look at how you can capture the tweets for that time period. It seems a waste to create a data table just for the job, so I'd be inclined to use something like Redis to store the tweets that you need
This can then be used to output the tweets you need, allowing you to simulate storing / capturing them, but then delete them after the hour-window has passed
Delivery
I don't know what context you're using this feature in, so I'll just give you as generic process idea as possible
To display the tweets, I'd personally create some sort of record in the DB to show the time you're pinging TweetStream that day (if it changes; if it's constant, just set a constant in an initializer), and then just include some logic to try and get the tweets from Redis. If you're able to collect them, show them as you wish, else don't print anything
Hope that gives you a broader spectrum of ideas?
I have a UILocalNotification that repeats every hour and I would like to change the message when it repeats so it is different, or rotates between 3 messages.
Does anyone know of a way to do this?
Also, it appears I cannot customize my repeating local notifications beyond once every minute, hour, day, etc. What I'd like is a notification every 15 minutes. I suspect that can't be done though... unless you know a way?
Many thanks for assistance you can offer.
If you wanna change the message you can acces to the scheduledLocalNotifications array in your app delegate and modify the message, but to do that you need the app to be running. I think it's better to simply schedule different notifications with the different messages you want to show.
About the repeating interval the simple answers is no, you can't create your own repeating intervals. This is one of the many limitations that UILocalNotificationhas. Many apps (included mine) had solve the problem creating a queue of notifications. I explain that topic here
