ALL SOLD - OFFER CLOSED

We have 5x Dianemo licenses that were scheduled for delivery this week but the project they were destined for has been delayed by 6 months. So we've decided to offer them to forum members at a very special price of $169.95 USD per license if purchased in the next 24 hours.

In addition if you purchase any of our HDMI-CEC software for Raspberry Pi, such as Raspbmc-CEC, RaspSqueeze-CEC or RaspCEC-Pi, when you purchase one of the Dianemo licenses above you can get an unlimited version of the HDMI-CEC license for just $99.95 USD (a $60 USD savings). The unlimited license allows you to install the software on as many Raspberry Pi's as you like on a single Dianemo system. Its a great deal - its the license most Pro installers choose.

These are great deals that will allow you to build your own Dianemo system for an unbelievably low cost. So don't delay purchasing one of these as they will sell out very quickly. All orders must be paid by Paypal and this offer is strictly on a first come first served basis.

To purchase please PM me asap here on the Forum or email me at inquiries@ellipticalcurve.com

All the best

The url below points to a new Web page I've created called 'HDMI CEC Guide' that will cover all things HDMI-CEC related. The 'HDMI CEC Guide' page is not about our CEC software but will be focused on universally useful bits of information to do with HDMI-CEC in general. I'm still dumping my scribbled notes into the page so expect it to grow considerably as I do that (I have far more scribbled notes than even I expected!).

http://www.ellipticalcurve.com/dianemo-products-services/hdmi-cec-guide/

Please take a look at the page if you are into HDMI-CEC or related stuff. I hope you find it useful.

All the best

PS If you spot any mistakes or have something you think I should add let me know. Likewise contact me if you have HDMI-CEC related questions that are not answered by the 'HDMI CEC Guide'

Users / Re: NAS - FreeNAS, LMCE or something else?
« on: November 14, 2014, 03:11:17 pm »
I'm looking for a reliable and easy way to store my data so that I can access it from any of the devices in my home while automatically backing up data. I'm in the process of learning about FreeNAS and I like what I see but I'm having a hard time determining if it's a good fit for me.

In order of priority, this is what I'm looking to do:
Critical Data Storage – I currently have ~30GB of data that I would consider critical and irreplaceable. Normally new content is added rather than changed. I currently use a combination of Dropbox and google drive to protect that data but I would prefer something a bit more seamless.

Replaceable Data Storage – The bulk of my content is recorded TV shows or movies for LMCE. That content is generally removed after consumption. It is not irreplaceable but would be a PITA if lost.

Usenet Download Server – I've recently started using sabnzbd, couchpotato and sickbeard on an old P4. I can see myself digging more into them and expanding into more related applications which are available as FreeNAS plugins. I suspect that if I didn't do FreeNAS that I'd be able to run these applications on my LMCE core. (right?)

I like the RAIDZ2 reliability in FreeNAS but considering my limited needs, it seems like it will be overkill...plus the cost of a FreeNAS box with four matching HDs is significant.

What options should I be looking into?

Thank you,
B34N

We used to build & sell our own FreeNAS based NAS's but eventually we realised that it just didn't make commercial sense (and it wasn't very 'Green' either) and now we just recommend that our installers purchased a respected, branded commercial NAS ie something like a Synology. We also always recommend using raided NAS's over internal hard drives as we've found this to be the most reliable solution by far. As posde says backing up your stuff is essential and rsync is almost universally the solution for doing that even in small commercial NAS's these days.

However...if your building your own system then its very likely that building your own NAS too is something you'd like to do. So I would say going FreeNAS etc on your own hardware in that case looks like a nice solution still (commercial rules don't apply in this case!)

All the best

Are you guys running/testing your installation 12.04 or 14.04 on SSD?
Is anyone using SSD for lmce?

Sorry to ask these questions, I am planning to collect hardwares this season(thanks giving sales) ;)

We've shipped Dianemo 12.04 systems with SSD boot drives for over 2 years now and have seen no reduced reliability or any issues specific to the use of SSD's. Our SSD based systems typically use NAS's with tradiyional spinning drives for bulk media storage.

The thing with hardware is: It changes so rapidly, that there is no real value in setting up a sub category. And as I tried to point in my first message, most hardware will work as a core. The only thing that could hinder it would be the network interface, and that can be amended by using PCI(e) NICs. For MDs it is a different story, but the first sentence still applies.

The one thing that would be useful is a wiki page that simply lists the hardware and whether a 12.04LTS desktop LiveCD will boot to the desktop. Simple and sweet.

We've just announced a new Restful Web API for the HDMI-CEC control of devices attached to your system. The software installs on a Model B or B+ Raspberry Pi and is compatible with Wifi or wired network connections. Simply attach a  Raspberry Pi to the same HDMI bus as your MD, TV, AV Receiver, DVD, Blu-Ray Player and you can control them using our Web API from a device template. Below are some example uses of the rest-cec API;

- Get a list of the available HDMI devices;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/
- Send a Volume Up command to the AV Receiver in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/avreceiver/vol/up
- Turn on the TV in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/tv/on
- Select Input 2 on your AV Receiver in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/avreceiver/input/2

All of our HDMI-CEC compatible products, Raspbmc-CEC, Raspsqueeze-CEC and RaspCEC-Pi (just provides CEC control), now support a Restful Web API for CEC Control that makes it extremely simple to interface them to LinuxMCE, Dianemo or any other Home Automation or Smart Home system in fact.

For LinuxMCE systems you simply add your Raspberry Pi to the HDMI device chain you want to control using a spare HDMI port on your TV or AV Amplifier. Your MD typically would then be either connected to another HDMI port on your TV or if you have an AV Amplifier it might be connected to an HDMI input there. Other device such a Blu-Ray or DVD player would be connected to other HDMI ports on the TV or AV Amplifier too. The Raspberry Pi can be connected to your LAN by Wifi so you don't need extra LAN ports near your TV/AV system. Your LinuxMCE system then needs a simple GSD device created that will allow your system to send commands to RaspCEC-Pi (for example) using simple HTTP GET and POST methods - See here for the basics of creating your GSD CEC device; http://wiki.linuxmce.org/index.php/How_to_add_your_own_GSD_device. Any of your Orbiters can then be used to control your HDMI devices - Change HDMI inputs on your TV or AV Amplifier, Mute the Audio or Power all your HDMI devices Off at once with a single command.

See below for some example CEC commands that can be sent using our Restful API  with simple HTTP Get & POST methods.

We have revised and simplified our pricing for all our Raspberry Pi software too - we now offer two very affordable simplified licences;

- $99.95 USD; Install on up to 4x Raspberry Pi's (on a single LinuxMCE/Dianemo System)
- $159.95 USD; Install on unlimited numbers of Raspberry Pi's (on a single LinuxMCE/Dianemo System)

The spec of RaspCEC-Pi is the same as for our RaspCEC-Pi Pro (for Professional AV/Automation System installers)  http://www.ellipticalcurve.com/dianemo-products-services/raspcec-pi-hdmi-cec-control-interface-with-web-api/ but does not include professional level support and therefore costs far less.

We also now provide a Web configuration page on each Raspberry Pi running either Raspbmc-CEC, RaspSqueeze-CEC or RaspCEC-Pi. Simply type the url below into a web browser;

Code: [Select]
http://<RaspberryPi IP>:8077
The Web configuration page enables you to scan the CEC bus that your Raspberry Pi is connected to so that all the HDMI-CEC enabled devices can be discovered and the configuration displayed. This information can be used when configuring or debugging the control of your HDMI-CEC devices.

When creating an external Device Template or Driver to enable your system to control your HDMI-CEC devices our new Web API supports the following CEC control features;

- Supported HDMI-CEC Devices - TV, Recording Devices (ie DVD, BD, PVR Etc), Playback Devices (ie DVD, Blu-Ray Etc), Tuner Devices (ie STB's), Audio System
- Supported Commands Power On/Off, HDMI Input Source, Vol Up/Down, Mute On/Off, Play/Stop/FF/RW/Pause,

Using our simple Web API device templates for LinuxMCE can be easily created allowing for the control of TV's, AV Amplifiers, PVR's, DVD, Blu-Ray and Sat Boxes that are connected to the same HDMI-CEC bus. Simply connect your Raspberry Pi to a spare HDMI port on your TV (or any other device in the HDMI chain) and connect to it over wifi or your wired LAN (I always use wifi personally) and your ready.

Below are some examples of how you can control the HDMI-CEC devices connected to your TV;

- Get a list of the available HDMI devices;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/
- Power Off all HDMI devices in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/off
- Send a Volume Up command to the AV Receiver in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/avreceiver/vol/up
- Turn on the TV in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/tv/on
- Pause the currently playing disc in the Blu-Ray Player in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/playback1/pause
- Select Input 2 on your AV Receiver in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/avreceiver/input/2
- Query the TV's power state in your HDMI chain;
Code: [Select]
http://<RaspberryPi IP>:8077/rest/api/v1/cecdevices/tv/
We expect to add support for more HDMI-CEC devices and additional commands soon.

This update is free to existing customers with Raspbmc-CEC or RaspSqueeze-CEC and is available as part of any new license purchased.

Please contact us for additional information inquiries@ellipticalcurve.com

All the best

The RaspSensor-Pi software for the Raspberry Pi Model B & B+ provides a user friendly Web UI to any 1-Wire sensors you have interfaced to your Raspberry Pi. We also provide a RESTful API to allow you to access data from devices connected to your Raspberry Pi via your 1-wire bus from LinuxMCE, Dianemo or other Home Automation/Smart Home systems. You can have a single Raspberry Pi running Raspsensor-Pi monitoring a 1-wire bus that connects sensors from all over your home or alternatively you could have several Raspberry Pi's located in different parts of your home monitoring a set of local 1-wire sensors for each room.

Each RaspSensor-Pi installation provides a Web page that allows you to quickly configure, setup and view all of the attached sensors in a Web browser. Each RaspSensor-Pi also provides a Rest Web API that allows your Dianemo or LinuxMCE system to get data from the attached sensors.

Sensors you might want access via RaspSensor-Pi;

- In-room Ambient Temperature
- In-room Humidity
- Motion Detection
- Ambient Light level
- Rain Fall Sensor
- Water Leakage Sensor
- Wind speed Sensor
- Wind Direction Sensor
- External Temp & Humidity
- Air Quality
- Solar Radiation Sensor
- UV Level Sensor

The RaspSensor-Pi software is licensed on a per Dianemo NerveCentre or LinuxMCE Core basis and can be installed on as many Raspberry Pi's as needed on any single system for $99.95 USD.

If you have any questions or for pricing info please contact; inquiries@ellipticalcurve.com or PM me here on the forum.

@_IF_

the central heating sets the designated maximum temperature. Each room has its own thermostate which is set once and forgot about. At least that's what I do.

@esperegu

There is german page somewhere that describes the total energy needed to reheat an area after it had been shutdown for the night. The consense is, it doesn't make any sense to do it.

@totallymaxed

re specific zones of comfort, see what I wrote to _IF_. Changing the zones is something that is only viable if you have devices that change the temperature fast. If you use regular floor heating, the time it takes to reheat the room is way too long. If you have other types of heat/cool inducing techniques this might be a different case.

If you have a pure underfloor system with its inherent high latency and thermal inertia then I'd agree. But many properties do not have that kind of system. Full heat recovering systems with heat/cooling in one system for example can take a room up or down in temp very quickly indeed (while recovering most of the sunk energy too). These are quite common here and in the US now in bigger houses, and increasingly in modern apartment developments.

So I do agree in pure underfloor heated properties constant running at fixed settings is probably the best option.

Here is another short video of some of the new UI widgets we've recently added to the new Athena HTML5 UI. The Athena UI will become the standard skin for Dianemo once Athena ships. The standard Athena UI skin contains many such widgets and we've heavily documented the PHP/HTML5 source files for the standard UI skin to make it as easy as possible for you to dig in and hack our skin into something that suits your personal needs and preferences.

Enjoy;

Also great would be the ability to detect temperature differences between inside and outside, and use a larger/smaller portion of filtered outdoor air to cool or heat the house.

I review a lot of HVAC designs for proposed commercial buildings and they all seem to be doing stuff like this nowdays.

Agreed re the relative outside/inside temperature comparison. Commercial installations always lead the way on theses types of innovation. Obviously presence detection in each room/zone is also helpful too to provide the 'is a human in the room' and allow the system to potentially build up an occupancy graph.

We're playing around with something that we are currently calling 'RaspSensor' for the Raspberry Pi. Its a software package that can be installed on Raspian that provides a simple SOAP API to any 2 wire sensors that are attached to a Rpi. The idea is that you'd just place Wifi equpped Rpi's anywhere you need some sensors. The Rpi is so affordable and compact that placing even 8-10 of them around your house is low cost compared to anything else we've found and would enable a rich sensor package to be located in any room/zone ie temp/humidity/ambient Light/ etc etc.
