very interesting lecture

Iron

Thank you Carol and Alex

No involvement in the internet projects.

Interested in wireless lighting control

Thanks, Carol.  Interesting presentation.

Iron

Thank you, Carol!

Iron

@Alex - i'm involved in the "internet of things" projects... mostly wireless (M2M type of communications), not the HomePlug/X10/BPL type of things...

Iron

@Alex - more re. applications... looks like the "smart LEDs" described in today's session are very close to my app. with RF controls...

Iron

@Alex - applications HB LED indication, PWM, etc... not general lighting.

Iron

@Alex - job function s/w, h/w and currently focus on standardization

Iron

Good to have access to recorded sessions...

Iron

Missed a class due to travel.

Iron

Looking forward to tomarrow

Thanks nice presentation

Hi Carol

Nice presentation

I wish we could spend more time on discussing the background information being given

But I guess that what wikipedia is for :)

 

Picking up another one after the day given

Thanks for participating, everyone. I'm learning from your experiences too. Sorry I can't answer all of your questions. But hopefully you  have picked up some new information to help with your work!

See ya'll tomorrow.

Blogger

@LevitonDave.  Devil's in the details and customer relations. For example cell phone companies have improved customer service. But you can only do so much.  

Attitudes to energy efficiency has changed dramatically in 30 years. Or maby we're circling back to the Carter days. In any case, I hope the utilities just haven't found the right approach yet.

Blogger

@carol- thank you , very useful info.

@Carol - Thanks for the reply.

Iron

@Carol - the only thing that has changed in the last 30 years is the communications medium.

@Ran  I won't bee going into the component specifics, nor control strategies. This is more of a into to the market. 

Blogger

@Carol - your approach to smart meters is typically what is done to provide time of day or demand metering. Control has been around for 30 years and usually customers get a break on their billing if they allow the control to exist.

@naperlou  I think the smart meter controlled by utilities is a public relations nightmare and unenlightened strategy. I think they should have only provided it as a benefit to allow occupants to see there energy use. Not take control from the beginning. Then once people are used to the meter and can see its benefits, then they can offer to reduce the bill by trading a small relinquishment of control.

Blogger

zigbee can be useful in other ways.  in IEEE Communications Magazine there was an article about a Zigbee headset that woudl allow one to roam an entire Zigbee enabled building and never loose connectivity.  This ia a good side benefit, for example.

Blogger

Carol,

I've worked with LonWorks Echelon in the past for data communication layer in the backplane for industrial control systems.

Hoping to learn more about Ziggbee in the near future for an application.

Thanks for the information.

 

Iron

not  a large area 2Km radius.

@PGGraham Tracking individuals is not available that I'm aware of due to the high bandwidth data and coordination required. Maybe someday.

@Carol - Do you think you'll go into more of the component level specifics later this week?  Also, what about various topologies of LED design PROs and CONs.

Iron

@kanjaa  Most of these are for diy where you spend $600, pick up a control module and several modules for the lights. Is the public lighting across a big distance? You might need more professional system. I'll talk about that on Fri.

Blogger

@CarolLenk Do you see a greater distributed integration of sensors and control or a centeralized intelligence like a BMS/BAS system?

btw, for home lighting - Home Depot has the Philips "AmbientLED" 12W (=60W incandescent) on sale for $15.   I have three here in my home office.

@LevitonDave, I'd be interested on seeing something that tracks individiual occupants, so, when I walk into an in-occupied room, my light and music choices follow me. I am working on something like it, but wanted to make sure it doesn't already  exist.

Iron

my latest playing with leds is modifying Xbox consoles and controllers - just for fun  :)

Time to go. Thank you Carol and Alex. See all tomorrow.

Iron

Zigbee has morphed several times. So just being Zigbee compliant may not mean what you think it means. I would wait till there are products out for Zigbee Light Link. It's the latest standard and has good security.

Blogger

@PGGhrarm There are commercial products to do this (I'm designing the next generation of one now). Typically they detect occupancy using heat or ultrasonic sonar and then communicate with light control either wirelessly or via LV wiring.

 carol,wich of the standards is the more indicated for public lighting networks control?

@PGGraham.  Not yet. But it would cool.

Blogger

Anyone need a good EETech? See me profile on LinkedIn

Iron

Thanks for another interesting talk Carol.  Any advice for someone is remodeling a house and wants to go to LED lighting?  Are there products they should avoid because the standards will be superceeded?  ZigBee for lighting sounds interesting. 

Thanks for the great feedback. This is definitely a field to watch.

Blogger

One think I'd like to see in home control and room lighting is intelligent monitoring of room occupants, such that the sound and light schemes will change depending on the time and room occupation. Have you seen anything like that?

Iron

we have lots of people in Naperville, a fairly well off city near Chicago, who are concerned about their "liberty" being compromisd by the Smart Grid and DSM.  If the DSM is active on the power company side it is precieved as being intrusive.  Of course, if it is not run from the power provider side it does not work.  that is the issue I see locally with some of this control technology.  i am for it, by the way.  I am just mentioning some of the issues I hear about.  so, security is key.

Blogger

@Carol: Could you pls add the question or part of it to your answers?

Iron

In the newest 6loPAN there are 3 levels of security. It's really a new issue for the industry. Older standards weren't designed with it in mind. The new Zigbee standard is much better prepared to deal with security.

Blogger

Thanks for the presentation. Have a nice day.

 

Iron

Once again, GOOD STUFF! very informative, thanks again Carol and Alex!

Iron

Typically energy savings or Green building is due to redusing energy when not needed. Having the lights go off when a room is unoccupied can save a building up to 10% of it's energy usage. Adding intelligence to this can improve the savings.

Same question - specific info on new TI part??

search for "TI Zigbee"

Blogger

@Carol, security is a great concern, not just information privacy, but malicious control of the network or plain old denial of service. Are these concerns being addressed by industry for home use?

Iron

Thanks, Carol and Alex and Digi-Key!

Alex - how do we get our certificates?

Thanks.

 

Iron

Thanks

great lecture.

Iron
Thanks for a great presentation.
Iron

I like power and control on the same cable for Low voltage lighting and such.

Iron

I,m Rodney B. Rutherford, retired and a college student

interested in psychedelic concert and entertainment uses

as T.V., film and cinematography. Good show, very very... Rod.

Iron

Hi,Carol:
Smart Building, Automation

to realize what function?

Any more info on the "TI chip announced in Jan"?  What's a part number or name, something to search for?

Iron

THANKS, VERY INFOMATIVE...

Thanks Carol & Alex & Digi-Key!!

Iron

security issues with using PLC in controlling publing lighting, means that i must move  to  Zig bee, will it be more efficient?

 

thanks Carol - great presentation. looking forward to tomorrow. thanks alex

Iron

Thank you for today's presentation Carol

Iron

thank you Carol,

Iron
From a cost perspective is there a preferred wireless network for home lighting control?
Iron

Thanks, Carol -- great session today.

Iron

, there is a zwave lock that is notoriously unreliable. making people use their keys.

Iron

What about patenting? 

Iron

What needs to be done to crack the slow adoption of smart control by US power companies (utilities).  Many foreign markets are moving much faster than the US.

PLC works well for retrofit communications/networking. no need to pull extra wires.

Iron

Will we see a BLUE light of death O_O?

Iron

@AlanJayWeiner - you must be Windows based :^)

Iron

Alex, the wired home is already givng way to wireless.  I think this will happen here as well.

Blogger

We build houses that way now, and include lighting, heating, and other home control right from the start. 

Iron

@Rerepete - it seems wireless networks precludes having to retrofit existing homes. also, it fits nicely with new homes, therefore no pre-wiring necessary

Iron

can just envision...  "darn it!   I can't open the door until I reboot my house!"

what is the power profile of these network devices ? in 10's of mA or 100'ss of mA ?

what about boot time for the house and possibly virus infection??

Iron

@CAROL:Can you, pls., give a couple of examples of your dream application for LEDs in the network of things/small things?

Iron

Hi,Carol:
smart-grid, meter,

is it related to LED?
What does meter do? only monitor voltage and current? 

At what frequency do the DIY modules normally function at? Any possible interfrences?

Iron

What % of LED market will use network and grid  control?

Are new housing builds now being prewired for smart honme systems?

 

Iron

Would the new 6loWPAN be good for small wireless security cameras, or is the data requirment too big?

 

Iron

Anyone know if I start adding Zigbee to my home if it will interfere or interface with my new Smartmeter on the AC line?

 

Silver

We've been using PLC to control LED displays for  a long time, but recently we did a patent search and there are recent patents for just that. Is there room for everyone to play?

Iron

Are you familar with teh EnOcean alliance and if so where do you think it will play in the lighitng control since it is tailored for lighing control?

OK, Hearing about Light link was worth the class all by it's self. Where can we find more detailed app development info on this?

Iron

@Alex - Internet of things...  Whether we like it or we don't like it, the industry and the consumer demands it, so we, the developers/marketers/sellers had better get used to it.  Learn it and do it.  It's a fact of life.  So, Ethernet, ZigBee, etc. are going to be around for a long time.  Let's do it.  Let's roll.

Iron

@alex -internet of things is important,

Iron

AS A CUSTOMER ENGINEER, I MAINTAIN SYSTEMS INCLUDING SMART SYSTEMS WHICH POWER, SECURITY, AND HOME SYSTEMS.

What can you do with DIY modules? What kind of applications are possible?

Iron
Interested in home control.
Iron

Smart control brings energy efficiency to much greater levels than just LEDs alone

INTERNET/NET of THINGS: it is innevitable, whether I like it or not. :o)

Iron

huge concern is security in an internet of things

Iron

what kind of LEDs are mostly used in the networking applications?

Iron

without control it does not work beyond the basic efficiency

Blogger

sure..if we have the communication in place, we can prettymuch control anything... not bad to learn communications

Iron

OSI STACK: layer 3 is link layer not MAC

Iron

This is a direct copy of the 7 layer internet protocol...

Iron

@raghu - yes it seems the presentation at this point is more networking, but it seems connectivity is interwined into most everything current and future. what do you think

Iron

I am mostly working fully smart homes, incl. internet connectivity, wired, wireless, & CAN in the house.

Iron

How's the power efficiency of the control circuit itself? Is it negligible?

Iron

Yes internet is everywhere it would be unwise to not explore the possibilities.

Iron

Echelon offers fantastic solutions for smart control over any network constraint - I've been using their products since 1991 with great success.

internet of things not on my imediate radar as such

low cost control of nodes is of interest...

ethernet and direct connection are the only communications

Iron

As another topic (along with LED lighting), I am also interested in ZigBee and Z-wave

 

Silver

smart-home stuff is interesting to me - on internet, less so

@alex - internet of things - general inerest, nothing specific at this time

Iron

My application will probably not be on internet of things.  Ethernet yes, but local only.

Iron

Poweline communications and  IoT is of interest

Yes Home Plug and other smart grip developments and net of things are in my radar.

Iron

the presentation seem to have drifted towards communication

Iron

Engineer just looking for general information.

Iron

Yes but only for a short hall controls.

internet of things is an interesting idea, but no current/near term apps.

Iron

yes, internet of things is great, but we need more cost effective communications

Blogger

@Alex: internet of things is important to me personally, but not on the immediate horizon for my work.

Iron

Internet of things on radar: Yes

Networking is important

Iron

There are some existing patents on PLC use to control LEDs, will there be infringemen issues? 

Iron

my application is professional architectural

Iron

what is happening, voive cut off?

Iron

Product Designer : Marine Lighting

Iron

any limitation on the distance when using PLC for public lighting control ?

engineering for research projects

 

Iron

the cost has to justify it.
