This doesn't even work:
<div ng-repeat="n in [42, 42, 43, 43] track by $index">
{{n}}
</div>

Hello, I am trying to create my first template. I have a data set that I am trying to display on a web page. The data is coming through on msg.data. I've tried using ng-repeat and scripting to get this into my template but it doesn't display anything.

here's the snippet of my template:
<div layout="row" layout-align="start center" ng-repeat="obj in {{data}} track by $index">
<span>{{obj.value}}</span>
</div>

I am seeing the object array when I am looking at the elements, however, ng-repeat doesn't seem to be working. Is there something that I am missing here?

I've also tried this:
<div layout="row" layout-align="start center" ng-repeat="obj in msg.data track by $index">
<span>{{obj.value}}</span>
</div>

My data object is simple, array of objects like this:
object:{
date: "2312345123",
value: "23.12",
}

I need help...I've got problems.

Congratulations derwish! Singlehub has been long awaited. I will try and test this on a Ubuntu server tonight.

Thank you,

@derwish , like this? https://blog.tonysneed.com/2015/05/25/develop-and-deploy-asp-net-5-apps-on-linux/

@derwish ,

This is the only instructions I have found for installing .net on linux:
https://www.microsoft.com/net/core#debian

Do you think this will work?

Thanks,

derwish,

Your controller looks awesome.

I'd like to start implementing this on my raspberry pi (either pi 1 model B or pi 3). I ran into dependency issues when installing mono on my pi 1 model B. The link to the .net install instructions is different then in your video so I followed the instructions on your video with out success.

Do I just need to wait for the node.js version to come out? Would that version still require .NET? I would assume not because node.js is based on javascript. Do you have any node.js development versions that I could try?

Looking forward to getting this installed.

Thanks,
neech

It is true that the NRF24L01 use a lot less power (apparently). I haven't used them so I would be concerned about the range of these types of devices? How many gateways would I have to build to cover my whole home?

On the Ethernet side, I am looking to do smart outlets: for that the ESP8266 makes sense because I could use the 120VAC power and convert it to 5VDC with a pretty small board using one of those transformer-less DC power supplies.

Maybe I'll test both scenarios before scaling up.

Thanks,

You could still do that with a separate WiFi router, right? I am starting to think about a new system that will have a dedicated router for my "things".

You're probably right on the adafruit thing, and the use of "their"...I am usually good about that. The question is, I want a computer acting as a controller and a WiFi gateway, a board with a sensor and an ESP8266 on it talking directly to the gateway. Is it possible and has it been done?

Well when you say it like that it sounds so obvious. However, the ESP8266 comes essentially comes with a boot loader and that's it. Are their sketches already completed to talk to a gateway with one of these?

TD22057, I love this idea. However, how are you going to power the ESP? I'd like to do the same thing but don't want to take the thing out to replace a battery. I also don't want to try and fit a 5v or 3.3v power supply in there...just curious if you thought of that yet.

Controller:
Re-purposed desktop computer
I am going to use MyNodes.net. I think it has a intuitive interface and am excited about creating my own objects. It is a ASP.NET based solution (which I am very familiar) so it seems like a good fit for me.

So I have the controller covered but here's where things get "fuzzy"

Gateway?:
What if ALL my devices are WiFi capable? Do I need an arduino, or single board computer gateway? I am planning on creating devices with multiple ESP8266 (adafruit HUZZAH) and am wondering if I do that do I really need a gateway?

I know it is probably good practice to go on a different subnet for these things, but that is just a networking issue, put in a dedicated WiFi router for your home automation devices and done. Or, is that essentially what a "gateway" does?

Devices:
I want all of my devices to be WiFi (ESP8266). Has anyone connected sensors to a HUZZAH or something comparable? How did it talk to the "gateway"

Any help is very appreciated.
