Coming Soon: ZigBee Control by PDA

Posted by timothy on from the wireless-torchiere-is-a-zigbee-pole dept.

palmtops writes "The new ZigBee (IEEE 802.15.4) wireless protocol designed for home automation is getting a lot of exposure lately and got some more exciting news today. Wired Home Weblog has a brief mention and press release about the first ZigBee SDIO card that allows your home to be controlled by your PDA. The card was introduced by C-Guys at Cebit today and will definitely add a whole new dimension to home automation."

      Zigbee is poised to become a standard that will control everything from home theater, TVs, HVAC, radio, lighting, security systems, garage doors, to mice, keyboards and joysticks. Among all these applications, it's designed to form ad-hoc networks. For example, your TV may be the first receiver of your remote control's signal to turn up the temperature on your thermostat, and it would pass the request from node to node until it reaches your thermostat, which then would use Zigbee to signal your furnace or air conditioner. It would also use Zigbee to operate the vent motors to allow for zone control (without wires.) You won't have to configure anything to make that happen, either. They'll form the network themselves via self-discovery.

      One of its big advantages for home automation is two-way communication. If you press the button for "garage door close", it will transmit and wait for an ACK, so you will know the door is closing. I think bi-di will also allow for "self programming" of your smart remote control. Hit a "program my remote" button on your Zigbee equipped TV, and hit the "learn a device" button on your remote, and the marriage happens. No more pile of remotes -- one will do it. And no more code books for your All In One remote. Plus, I think the pairing can be secured (although not cryptographically secure, it'll still be good enough for your neighbors' remotes to be locked out.)

      Because it was first designed for battery powered industrial sensor networks, Zigbee is designed for extremely low power for the longest possible battery life. The transmission starts instantly and is a short burst that is stopped as soon as it's acknowledged. The receiver will come active within 15ms. Zigbee remotes should last longer than IR remotes.

      Zigbee allows for 65535 nodes in a network, which is a lot more than the 256 unique addresses in the X-10 namespace. Oh, and in America, Zigbee is 40kbps, which is much, much faster than X-10 over powerlines (which I believe I read is something incredibly slow, like 60 baud.) While still a low-bandwidth network, 40kbps is plenty fast enough for device control, which typically uses very tiny packets of data.

      I was disappointed to find that Bluetooth could not become the home automation control protocol. One of the problems with using Bluetooth for remote control is that the discovery and connection process can take 3 or more seconds. While Bluetooth can transmit at a much higher data rate, it takes much longer to start up and more power to do so.

      While Bluetooth will still exist for things like headphones, I've decided to get excited about Zigbee instead, and I plan to buy a Zigbee enabled Palm device when they hit the market.

      Finally, I'm sure I got plenty of facts wrong above. I'll leave it to someone else to post corrections, I'm going to bed.

      Is it really too hard to get up to turn off a light?

      No, and if that was why people installed home automation systems, that would be a valid jab. Very few people will spend hundreds, or in some cases thousands, of dollars just to avoid getting up. My own needs were based on practicality. One, my home is set back far from the street, and stumbling around in the dark outside when I come home late is not my idea of fun. So, my system is set to turn on the outside lights a half hour after sundown (even though the sun has set, it's still pretty light out for half an hour or so). This way, they're on when I need them, and off when I don't. $5 Walmart-special timers can't predict sun rises and sets. They have to be reprogrammed ever season, at least if you're like me and hell-bent on giving over my hard earned cash to my utility company.

      Two, I have an automated random routine for when I'm on vacation, to give the house a more lived-in look. $5 timers can't do that for you, either. In fact, they make it more obvious to criminals. If you have an expandable system like the one I use, HomeSeer, you can use it for more than just lights. For example, I have a humidity sensor in the basement that signals the system to turn on the dehumidifier down there when it reaches a certain level. Unless you get a VERY expensive model, most dehumidifiers aren't very accurate, and considering how much electricity they use, I only want it on when it's necessary.

      Since I had a system in place to handle the practical needs, I started using it for the "impractical", too. I leave one of the X-10 wallwarts plugged into my vaccum, and if a call comes in while I'm vacuuming, it gets turned off so I can hear the the phone ring. When I had multiple computers in the house (since replaced with laptops), I had the system shut them all down at night, and sent a Wake-On-Lan around 5 PM so they'd be on when I got home. Or, how when I switch MythTV to DVD mode, the lights dim in the living room after a couple of minutes, and the front blinds close to block the glare on the TV.

      I have my bedroom lamp set on to start dimming up in the morning gradually. I get up before the sun, but have a hard time climbing out of bed if it's still dark out. So, for about 15 minutes before my alarm goes off, the light starts dimming up (yes, it's bad grammar, but that's what it's called in "the community") starting at 1% and increasing 1% per 15 seconds. When the alarm goes off, it's at 60% intensity which isn't blinding first thing in the morning, but light enough to get up by. This may sound stupid, but since I'm not a morning person, getting up has never been easy for me. Since I've set this up, I've found I only hit the snooze button once or twice anymore, rather than 5 or 6 times. I also wake up in a better mood and more alert.

      True, most of these are minor conveniences, but it's the 21st century and computing power is cheap. Why not take advantage of it? Just because YOU don't see a value you in them, doesn't mean others don't or are lazy because they do. I've saved approximately 45% on my electricity bills since automating my setup, and that's before switching to fluorescent where practical. I wake up more refreshed, and don't worry about my home when I'm out of town. There's plenty of value in it for me.

    Homeseer has a web interface- so control of these devices via a pocket pc is possible now. There are plans for Zigbee control in the future as well.

    I think HS has the correct paradigm- a central PC controlling the house. Certainly you need to keep it on- but adding a $100 card to every machine you want to control devices seems silly when anything with wifi can do the job- and will allow you to read slashdot as well.

    And yes- my garage door can be opened up via my webpage. No- you can't have the link.

    Reminds me of a Steven Wright line:
    One day, when I came home from work, I accidentally put my car key in the door of my apartment building... I turned it... and the whole building started up.... So I drove it around.... A policeman stopped me for going too fast... He said, 'Where do you live?'... I said, 'Right here.'

    I think the main tradeoff here is data transfer rate vs. battery life. For PC bluetooth stuff you want high data rates... for tracking your pets going in and out, you really dont need or want xMb /sec transfer rates.

    there was a presentation/workshop for Wireless Sensor Networks (WSN) about two weeks ago in my university. WSN is the same network (protocol) family of ZigBee. Actually, Ziggy is only one of many still-under-development WSN protocols. Even if zigbee is far ahead in the development roadmap than the protocols developed in our department, it is proprietary and all of these still have way to go. as for the purposes of WSN in general and zigbee just think about wheather/traffic/air polution monitoring through a network of sensors which elaborate data locally. these networks provide a wireless infrastructure for gathering, merging, aggregating data that is stored on senor nodes and who are relative to the observed process. this may still be rather theoretic, but the low power requirements and operating in an environment with limited resources differentiates WSNs from other network systems and there is a lot of research going on in this field. i hope i gave you some more info on what Zigbee and WSNs in general are (or should be ;) about. i explained mostly the point of view of that workshop, naturaly. personally i think that WSN and personal computer networks are not the same thing, at least wsn don't try to replace pc networks since the scarse bwdth of wsn could never offer you video/audio streaming or online gaming ;)

    Who needs fancy stuff like this when pda + bluetooth + computer + X10 = home automation from your PDA. Example: http://otaku.org/weblog/?page_id=2 And I never use this (though I only have 2 X10 modules at the moment.) As for security, I'm not sure I'd want to "home automate" anything I mind people being able to turn on and off from outside my house.

  24. Not particularly exciting by horza · · Score: 1

    Exciting news would be a cheap CAN node with some practical functionalitiy as an alternative to the ridiculously expensive CBUS. Or a Python equivalent of the excellent but Perl "Mister House". I thought xAP had potential but it's turned into a crap Windoze app. Shame. Sorry but there is currently no cheap but decent HA stuff out there except the slow and error prone X10. We are still living in the 60's.
