Smart bulbs revisited.

In The right / best way to control a light I discussed how switches vs smart bulbs depends on install. Here I'd like to update with some of the experiences I've have with smart bulbs since then. To summarize here are my note in my compare sheet.



Note you can get some crazy cheap deals on SYLVANIA / Lightify / Osram stuff right now.
Like this $9 bulb and gateway bundle still on sale. I got a bunch to sample to eval on sale. For less than $75 I got 5 bulbs, a gateway, a motion sensor and 2 dimmers. Awesome deal except only the bulbs worked OK for me. I even bought the Sylvania Smart Home 74099 Sylvania LIGHTIFY Smart Switch 8 Functions/ 4 Buttons, White, still only $10, which did at least seem to work controlling the bulbs but is not seen by Homeseer and so can't be use as a general remote. Homeseer did see the bulbs and motion detector did turn the lights on most of the time it should though seldom off. The dimmers worked for a bit then died. They were not seen by Homeseer. So all in all pretty much a waste of money and time. Too bad give a 4 pack of white Lightify bulbs is going for as low as $16 onsale versus a 4 pack of Hues which go for around $40.  Though I did stumble a 6 pack once $50 a couple years back. Which brings us to price.

I see a lot of posts saying Hue bulbs are too expensive. I think that is mainly because people seem to compare the Hue color bulbs to white version by others. If you compare a 4-pack of white bulbs they cost about the same as Sengled Smart LED Soft White A19 Bulb 4-pack.  Or Cree 60W Equivalent Daylight (5000K) A19 Dimmable LED Light Bulb in the (6 Pack) compared at a per bulb price.  You even here people going on about the new Wyze bulbs but they are about the same price and do not work with anything other than the Wyze app.

I had planned on using then instead of upgrading the Hue gateways after Hue basically cut V1 one users off.

Other than the price I'm liking the Hue motion sensors more and more. Homeseer does not always seem to get non motion event updates from them but otherwise it is nice to have them automatically turn the lights full on and off without need of setting up events. Especially after having to redo all my lighting related events after the v1 to v2 upgrade.

The Lifx bulbs seem like a good alternative if you want to avoid getting a hub though the white bulbs cost more.  And like I've said above, the one I got for eval had a lot of issues. Still the outdoor BR bulbs with IR look interesting but if you do the math, unless you want to light your yard in color, even at the $50 sale price you can get a Z-Wave switch, 2 LED bulbs and a 2 serious IR floods for about the same price.  And the IR floods turn themselves on and off as needed automatically. If you want smart flood light bulbs, Hue has new outdoor bulbs. 2 for $50.  Still cheaper to go with 2 LED floods and a switch though.

Tp-link (kasa) bulbs cost even more and they require cloud access. I have a couple of their outlets I got on Prime sales for $5. The cloud link fails way too often.

Even the TRÅDFRI bulbs are more now.

Etekcity, while I like their smart plugs for non critical stuff. Very cheap and so they have been more reliable the the TP-link ones despite being cloud based as long as you call their API directly. Going through IFTTT stopped working awhile back. I don't know if they ever fixed it because talking directly was so easy to do. But their bulbs are more than the Hues so why?

Z-wave bulbs like Aeotec LED Bulb Gen6 Multi-White are even more.

There are more of course many others, some even cheaper than Hue but one of the main things to remember is what do they works with? So in the long run you will probably end up tossing them unless remote control via your is all you ever want.

The right / best way to control a light. It depends.

Given all the flame wars over smart bulbs vs smart switches it seems time to make a post to use in replies. One guy even suggested using both to avoid:

  • People turning off the switch. It should be obvious that even if the switch is smart, if it is off it is off and you can't control the light till you turn the switch on. Covering the switch with something like the Magnetic Switch & Outlett Cover for Toggle Switches ought to make people a think before flipping the switch.
  • Smart bulbs coming on after an outage (they only do this after an outage not a flash). To avoid the power on after an outage all you need to do is put a bulb in an unneeded location and create an event to turn off all or some of your lights if it comes on. Note too the reason these lights come on if the power is cut for about a second is so you can manually override them if other control is lost. Some do have a hidden parameter to turn this off if you really think you need to. Google it. Personally even though I live in the country and have all my computers and AV and network equipment on UPS to handle the flaky electric I've only had the lights get triggered by this a couple times in over a year now so I don't see it as much of an issue.

There really is no point in chaining smart devices and in fact is can cause issues if the smart bulb is Z-Wave or Zigbee in that these are mesh devices and removing power from them means the mesh is regularly disrupted. In the best case this causes lag and in some cases might cause devices to miss commands. Depending on the WiFi bulb it may cause connection issues as well since most of them work via a cloud interface of some sort and disconnecting them will require them to establish a new connection to that cloud to receive commands. Then there is the whole bit about updates which would only be able to install while the the light ia powered. Bottom line these devices are designed to be always on so powering them off for extended times at your own risk.

As for the "right way" to control a light. First off it would depend on the best fit for the env.
Other than a bed room:

  • I would use a motion detector as the primary trigger with voice backup
  • As a secondary I would the dumb switch (with a magnetic cover to avoid accidents) and a timer that shuts off the light after X minutes of it being turned on and/or no motion detected. In many cases this also tied to turn off other devices in the room like a TV.
  • I might use a wall switch or a smart bulb generally dependent on the level of control required. As in a smart bulb if I want to control the bulbs singularly or a smart switch to control a group of bulbs in a room. Just do the math. Which is cheaper to replace the bulb(s) on this circuit or the switch(s). Factor in if dimming or color changing is required of course.
  • If a dimmer is wanted with a single bulb the Hue and Lightify dimmers work great for that and is pretty cheap too. Note the Hue dimmer with bulb bundle is generally a good bit cheaper than the two separately.


For a bedroom or other place where you want more manual control a smart switch is used without a motion detector.

Simple right? Like most of this stuff there is not general "right answer". The best fit is on a case by case basis. Though let me repeat again always try and get devices that work with multiple hubs because it is pretty much a given at some point you will want to move to a new one. Whether is a shutdown like Resolve or Lowes' Iris or issues like SmartThings has been having or incompatibility between version of hubs like Lowes Iris' and SmartThings' V1s and V2s or you just need a feature some other hub has and your current one does not.

Want a second opinion?

Note some of these are a bit one sided and a couple get into Rube Goldberg style options.

Hue lighting vs Z-Wave - you probably want both

Common applications

I was just talking to a guy about which is a better fit. He said wall switches because most of the lights in his house a single switch controls all the ceiling lights in a room. Could be as many as 6 bulbs on switch so he is saying wall switches are cheaper. Wiring wise, my home is just the opposite. So is my shop though my barn is wired like he described. My barn is wired like a office with sectional fluorescent lighting because you do not want to step on something sleeping in a shadow. Other than the barn and some outdoor lights almost none of the lights are multiple bulbs. Almost every one is controlled by multiple switches. My house and shop are both very open plan with vaulted ceilings and 2 to 3 doors on almost every room. My living room for example has 4 ceiling lights and a fan light combo. Only 2 of those ceiling lights are on the same circuit and all of them are wired to 2 to 3 switches so you can control them from related entrances. Any home designed to be energy efficient would be done similar since you do not want to be turning on all the lights when you just need one and you do not want to have to cross a dark room to turn on a light. But even if your room is wired with 6 bulbs on a single switch, being able to control that group lights individually or as group like adding Hue bulbs would do would be seem to be an added feature over the wall switch as well.


Cost

First if you are looking at smart lighting I'd kind of assume you have, or will get, some sort of home automation hub. Not long ago I replaced several hubs, including a SmartThings, awhile back with one huge Homeseer server that oversees all 3 buildings. So the real question is never a Hue vs a Z-Wave hub. Hue is an add on not a central controller any more than Nest or Echo is. You can sort of do some limited stuff but again if you are reading this you have probably already out grown those limitations. Personally I have most my controlled lights linked with motion detectors so the lights come on when I enter and off after 10 minutes of no detected motion. I can also control them using Echo Dots around the house and a few are also linked to local z-wave and Hue remotes. Another advantage of Hue is they can be controlled by multiple controllers since it is in effect a WiFi enabled device when the Hue hub is used. Note the SmartThings hubs can talk to the Hue lights directly but people seem to have less issues using the hub instead.

So bottom line, the only bits that differ between using Hues or not are the Hue stuff and the wall switches. If you have even 1 Hue light you are probably going to have the Hue hub so it is really a non factor after the first bulb but lets looks at your example of a first time Hue install 2 bulbs on 1 switch:


  • 453761 Hue Lux 60W Equivalent A19 LED Personal Wireless Lighting Starter Kit sets you back $40 and that is really all you need to turn them off and on via phone, Echo ect. You just leave the switches on. You can turn them on locally by flipping the switch off and back on. Now this brings up what I see as the only real downsides to Hue.  1) if you turn them off at the switch they are off and 2) they all come on if the power goes out and back on. Though a flash outage or brown out does not seem to flip them on. 
  • if you want local dimming or to be able to turn them off locally add a 455394 Hue Wireless Dimmer Kit, 1 Dimmer and 1 Hue White Bulb at $35 yes but note what does yield you an extra bulb to use else where too. So you really need to compare that to 2 wall switches which would be $5 more. Plus the Z-wave dimmer only will work with certain bulbs. If you want dimmable you really out to go with Hue.
  • Lastly if you have family that forgets and flips switches off add a Mitzvah Family 1007 Magnetic Switch and Outlet Cover for Toggle Switches, 6 Pieces at $20 that works out to $3.33 EACH
  • Now after you have the hub I found 3 packs of 455295 Hue White A19 LED Bulbs for as little as $22. Looks like on Amazon right now the best prices are on 2 packs for $18 but also watch for 3 packs. Always good to grab extras when they are cheap.
  • Or you could get a Hue bulb with remote + the switch cover $38.


Note assumes you have usable bulbs for the switches already. If not you need to factor in at least $5 a bulb for the wall switches as well and their might be issues with dimming them.

Also some other bulbs work with Hue. For instance I have a GE Link Smart LED Light Bulb, PAR38 Floodlight (3000K), 90-Watt Equivalent that seems to work find with Hue though its short neck and wide face limit the fixtures it will work in. I got it for just $14 though on sale.

Now you could get something like the GoControl Z-Wave Dimmable LED Light Bulb, LB60Z-1 for $17.50 but then you have all the same issues as the Hue bulbs and none of the advantages. Plus each bulb is twice as much.

If you start talking 3 way you are looking at more like $60 per circuit going with wall switches. $80 for a 4 way ect. Plus I ran into issues with a 3 way setup for example where the only bulb that would work was an incandescent because it needed a trickle current through the bulb like the old X10 stuff did.  

All the above said I still like wall switches for specialty lighting like track lighting or even flood lights as even the white Hue floods are still on the pricey side at $22+ each Same with their 468926 Hue White Ambiance E12 Candelabra 6 Watt Connected LED Bulb. In both cases the applications generally call for 2 to 4 bulbs and in the case of floods I want something brighter than 60 watt equivalent. Not to mention they are not rated for outdoor use.


Research update: what about Ikea's TRADFRI lighting

It does look like it might be an affordable alternative to Hue once it is more supported given the prices I hear people are finding. Right now comparing the Ikea site prices to Amazon's Hue prices Hue is slightly cheaper. Alexa, HomeKit and Google Home support is supposed to be coming soon.If you are hardcore DIY there is a SmartThings hack out there to get it to work. And Homeseer looks to have a plug-in in the works. So it might be a question of waiting or taking a risk that this will work for you some day but it is not ready for the average consumer yet. Note Ikea does not have an outdoor option yet but they do have a track lighting one. Though again at $20 / bulb that can get pricey real quick. Their candelabra option LED bulb E12 400 lumen is a cheaper than Hue $15.
