Osram/Sylvania Lightify (it works)

#134

I tried to connect it as OSRAM tunable light but I couldn’t do it. I am a total newbie. I just connected the hub a couple of weeks ago. I probably did something wrong.
I don’t know how to use the code you posted. Are there instructions posted somewhere?
Also, I read in one of your previous posts that v2 users would lose local access. Would that happen only for the devices controlled using your code or for all devices connected to the hub?
I understand the color temperature feature is not controllable on the $20 bulb. I don’t really need it. I just picked up the bulb hoping it would work as a cheap ZHA repeater for the open/close sensor in the freezer which is going through batteries like a kid with candies.

You’ll need to create an account and log into the developers section to get into the IDE. Choose the section My Devices, then click on the bulb. The next screen will give you a lot of details, but you want the Edit button at the bottom. This will give you dropdowns. Under deviceType choose the OSRAM tunable, then click Update at the bottom to apply the new device type.

That worked, thanks! The lag is very small, less than a second, comparable to the GE lights.
Now if only it would repeat ZHA signal I would be a happy camper. Is there any way to check directly?

Not easily. If you had a zigbee sniffer you could try and monitor the traffic going to/from the bulb. One other idea is to place a different zigbee device very far from your hub until the signal doesn’t reach, then try placing the Osram somewhere in between and see if you regain control of the far device.

I did check directly. They don’t repeat ZHA signals for other brand devices.

Sadly ZigBee allowing that completely breaks all advantages of Zigbee and ZHA. It makes the idea of a reliable self healing mesh unachievable unless all you buy is the exact same brand of all devices.

I also heard the rumor that they did repeat ZHA signals, but my ZHA sniffer and tests to heal a network proved they don’t in reality.

The SmartHome wall plugs though, do reliably repeat any ZHA signal from any brand. Installing two of those in the same locations as where I had my Osram Lightify bulbs made a huge difference right away.

You need to actually unlink all ZHA devices in the area you want to use the relay boxes. join those boxes, then join the devices further out. ZHA is not smart enough to look for the closest and strongest path.

It’s actually a little different than that. If you take the ZHA coordinator off line (not all individual devices) and wait long enough for all the battery powered devices to wake up and realize that the network is out, then everybody will find their new neighbors when the controller comes back. This is an important feature in zigbee, and used in the sensor nets that deploy thousands of devices. It why unplugging the hub forces a network heal for ZHA.

But there has to be a decision point forced.

ZLL doesn’t require a coordinator, though, so you can’t force the rebuild the same way.

The range and repeater FAQ has some examples.

On the Osram bulbs, I’m sorry to hear it, but I believe it. Although since they have done a couple of different firmware updates, and they do use different profiles in the EU and in the US, there’s always been some question as to whether every lot has the same behavior or not. I’d really like to hear their engineers verify The current intended architecture.

Thanks for checking. Back to Lowes it goes.

I am very new to SmartThings and was also interested in the Osram Lightify bulbs, so I contacted their engineering group for clarification. I have no idea why the bulbs would repeat for some people and not others, but according to their engineers, the current intended behavior is to repeat all Zigbee ZHA signals. For reference, the following is my question and their response:

Hi. I am interested in your smart connected lights, specifically the Lightify tunable white bulb, the Lightify color RGBW bulb, and the color RGBW LED Flex Strip. I have a question. When connected to a Zigbee ZHA network hub, do your smart connected lights “repeat” signals from all other zigbee devices, or just from other Osram bulbs? I searched for this info online and I found one person that said your bulbs DO repeat everything, and another person said they tested it and found that your bulbs DON’T repeat other Zigbee ZHA signals. Please let me know the true answer to this question. Thanks for your time. (PS: I am in the United States, in case your bulbs behave differently depending on the country it’s sold in.)

Their response:

Hello Jason. We sent your request up to the Lightify engineering group for evaluation. They sent me back a comment this morning addressing your question. The reply was:

We recognize that people want to use Lightify lamps as routers and fully support that functionality. All of our bulbs and fixtures (both US and European products) act as routers for all ZigBee devices in the same network, not just for our own products. This means that routers and sleepy devices from other companies may send messages through the Lightify bulbs and they will be “repeated” as expected. The reason that for the confusing results is that routing in ZigBee is complicated: route selection rules vary from device to device and the RF environments are constantly changing. There is no doubt that a Lightify bulb will forward a message for another device, but it’s hard to predict when and how the other devices make the decision to route through the Lightify bulb.

I hope this addresses your concern appropriately. If you need additional assistance please let me know.

I double checked my system since I could have sworn that I had seen the bulb repeating messages a while back and it looks like mine is still repeating messages. If you look at the sniffer log, you can see the sensor (device 8657) sending a message to the hub (device 0000) indicating that I opened the door in the middle frame. The bottom frame frame, you can see the details of the message where the sensor is sending the message to the bulb (device d2dc) and the bulb is immediately forwarding the message to the hub. Just after that, you can see the hub sends an acknowledgement through bulb followed by some commands to the bulb.

Thanks for sharing that! Very interesting. :sunglasses:

Was the bulb sold in the U.S. Or the UK? Model and firmware?

Great stuff. Thanks for sharing!! I have seen my Hue bulbs both relay traffic as well as allow a child (battery powered device) attach to them. The child device I’m not 100% sure but pretty sure (strong 90%) its been awhile since I played with that.

For clarity, we should mention that JohnR is referring to some Hue bulbs which he has connected directly to the SmartThings hub, not to a hue bridge. (Also verified by a network mapping tool.) That’s a whole different topic. :sunglasses:

US tunable white bulb.

I bought the Lightify Soft White A19 bulb at Lowes the other day. It’s pretty much the same as the Tunable White one, without the color temperature adjustment.

Pros: The light is nice and even. It reports attributes correctly (keeps SmartThings in sync if controlled by another ZigBee device) and ZigBee groups work fine. It supports optional dimming for on/off. I confirmed that it acts as a ZigBee router.

Cons: Dimming the bulb to minimum turns it off, just like the Tunable White one; so it’s not possible to know if it’s off, or just dimmed to minimum. It turns on instantly, but turning off it dims down over one second; the Tunable White does not do this.

In conclusion I think this is the best general purpose ZigBee bulb, for the price.

I sure wish they would come out with a color bulb for the US!

It is also much lighter than the GE bulbs. I didn’t weight them but I’d say nearly half the weight.

So would you say the Osram is better than the Cree lights? Has anyone used the outdoor bath lights, I am thinking about replacing my solar lights.

If Osram works as a zha router, that’s a nice plus.

Yes.

Cree didn’t properly implement ZigBee attribute reporting, and also used the wrong device ID. They are not reliable, one of mine just stopped working and I’ve heard that others had the same problem.

I emailed Cree to see if they had a firmware update and rather than reply with at least a form letter they didn’t reply at all.

I contacted Osram and they said sometime in early 2016, the RGB bulb should be available in the US.
