Osram/Sylvania Lightify (it works)

Interesting find last night. I’m still trying to 100% verify.

But it appears only the fixed dimmable but non tunable lightify bulb is randomly turning on.

So on the lightify hub everything works fine and nothing turns on randomly. with both kinds of bulbs.

On the Smartthings hub 2 of the dimmable (not tunable) bulbs randomly turn on in multiple light sockets. Usually once an hour. Sometimes they go for 8 hours. Very intermittent. Nothing in the IDE logs other than they switch on.

and 2 of the Tunable bulbs have never turned on by themselves.

Have flipped them between sockets. Deleted them, reset the bulbs. re-added with different names. Always the same results.

Can anyone else confirm they have a Tunable lightify bulb that randomly turns on. Or is it just the dimmable ones?

I’ll update once I test some more after work tonight.

They are all current with firmware, from the lightify hub.

Watched it off and on all day. The cheaper non tunable bulb keeps turning on the smartthings hub. The lightify hub keeps working fine.

I have just added 7 more of the more expensive tunable bulbs back in to the smartthings hub. I’ll see if any of them randomly turn on.

Will update in the morning.

Sounds like the non-tunable bulbs didn’t get the same firmware fix.

Maybe try turning off the insecure re-join feature of your hub and see if it still happens.


So just starting out with smartthings. Bought bunch of tune able bulbs and non tune able at lowes. Few questions:

1- with smart bulbs, I assume you always need to leave light switch in on position and let smartthings app control it correct?
2- from my testing seems if the light switch is hit it will reset the tune able lights settings ex dim and color range?
3- if true is it mainly just getting use to using app and just try not to use the switch? Any type of cover or lock people use to block themselves or train from switches.
4- Are zwave switches better then bulbs in the long run? Do they allow the app and switches to work simultaneous?

Giving it a try. Hub rebooting now. What’s the worst that can happen…

So reading this, that is turned off by default correct?

Thanks for the idea. I’ll update status tomorrow.

You need to always have power to the smart bulbs. But there are various switch alternatives. People handle this issue in many different ways. For example, at my own house, voice is the primary way for controlling lights via the Amazon echo and then we use the Phillips hue dimmer switches as a parallel means of control. Different things work for different households. The following thread discusses many different options:

People tend to have very strong opinions on the bulbs versus switches discussion, but the truth is there is no one right answer. Different things work for different households. Some people use only smart switches, some use only smart bulbs, some use a combination. The following thread is a good place to start to see the various arguments and opinions:

I think the insecure rejoin is enabled by default. The option to disable it is fairly new in response to the potential security hole.

I think the worst is that if the lights coming on is the result of them reconnecting in this manner, then they’ll simply drop-off the ST network and you’ll have to reset them and re-connect.


My quick feedback. In the same situation is you.

1/3. Yes power has to stay on for the bulbs. They make child covers for switches that would work. You can still flip them with a pen from the side but not too easily

  1. Yes that is correct. There is a custom device type that should be able to fix that though. On my to do list.

  2. Zwave switches are the most cost effective in my eyes as you can use regular bulbs. And the bulb status is updated if someone flips the switch. However in some cases smart bulbs have advantages as you can have bulbs turn off and on individually. So if you have 4 bulbs in a fan. With smart bulbs you can only turn on 1 or 2 or 4. Or if you have colored bulbs you could change each to a different color. More flexibility.
    Lightify makes a great switch that covers your normal switch. Works great with their lightify hub. Some great people on this forum are trying to get it to work. Unfortunately they have hit a stumbling block. But they are still working on it.

My house does not have neutral wires. So… Zwave switches will not work. That’s the path I was going to go. But since rewiring would have been cost prohibitive. I am going the smart bulb route.

Also make sure to update the firmware on your bulbs as well. If you read up a few posts you can see the issue I am working on with the non tunable bulbs.

My opinions. Noticed some other people have replied as I typed this. Equally valid.

Let you know what happens. Guess next thing is a email to Osram support. Depending on what happens.

Security is a good thing…

Is there any way to know when a firmware update is released with these bulbs?

Thanks for quick replies. Now to decide if I want to go the bulb or switch route. Are these bulbs safe to put in outside fixtures?

Lady time I checked, the Osram Lightify bulbs were rated indoor only. The garden spots are rated for outdoors.

As far as I know, the only smart Zigbee bulbs rated for outdoor use are some of the GEs.

Neither the Osrams nor the GEs are safe to use in a fully enclosed fixture ( they’ll overheat).

There are some community members who have successfully use the bulbs outdoors in sheltered locations in ventilated fixtures, but the manufacturer doesn’t recommend that for the Osrams. :sunglasses:

So then I’m guessing if people want to automate a outside pole light they would prob use a zwave switch?

Or a Zigbee light switch or WiFi light switch, anything that works with SmartThings. :sunglasses: Or they use a smart bulb rated for outdoor use like the GE outdoor floods.

So interestingly enough… With that change to the security on the hub the bulb quit turning on. And does continue to work.

Not sure what that means. Right up until the change it continued to flip on every hour or so. the 7 other bulbs on smartthings worked as normal. I’ll move some more over tonight and see.

But so far so good. Just checked and everything is off like it should be.


I have an Osram Lightify Classic, which is a simple while bulb with no colour and no dim. I can’t seem to find a device handler that works though. Any ideas?

Clear dome? All Lightify bulbs at least dim. You’re probably running into the endpoint issue. First try using Zigbee Dimmer and/or GE Link Bulb. If they don’t work, try post #251 in this thread.

Hi there, yes a clear dome and you’re right, it does dim! It said non dimmable on the listing I purchased it from but the box definitely says it dims.

I’ve also got it working now. Somehow I wasn’t copying all of the code for the “Lightify Surface” code above. Not sure how I managed that, but it’s now dimming and turning on and off.

Not bad for the price!

Thanks for your help!

I have a Philips hue bulb in a fully enclosed globe enclosure which screws water tight with a washer… no issues so far… but haven’t used int he middle of summer… installed in sept.
