There are specific device type handlers for OSRAM bulbs. I have some on the specific Osram DTH and other on the more generic Zwave white color temp DTH… I have played around with various DTH’s but still have these bulbs intermittently become unresponsive, although it is better than about 6 weeks ago.
In the piston’s main page, disable command optimizations and try again please
Bingo, that did the trick
Thank you very much
I have several/many Osram bulbs.
On few occasions (very few) I have experienced that in a group of 6 spotlights, one would not respond to commands all of a sudden. The 5 other would turn on and off as normal, but not the 6th one and was just “stuck”.
I did not dig more into it, I just turned the power switch off and on again, and then it “reconnected” and worked fine again.
Just my 2 cents of experience.
BTW, I bought the Osram bridge/hub, with the only purpose to update firmware, I assume you have updated yours to newest firmware. (I have not read your previous posts sorry)
I have used your device handler and works much better than the generic zigbee rgbw.
I am using the app CORE and when I choose to set color, I am not able to choose the white channel.
Even if I choose just plain color White, it’s still a white created by RGB mising.
Would you have an idea on how to control the dimming, on/off channel of the white through Core?
Ah just found in CORE there is an option RGB/W that I can choose WhiteOn or WhiteOff. My mistake. Tested and works like a charm
Perhaps a stupid question, but can any of you confirm that a Osram bulbs set to 1% level, uses less power than when set 100% right?
Meaning I save money on my powerbill by turning down the level of light when not needed as much?
They’re nominal power is 10W. That’s a 240Wh per day power consumption, that means 7.2kWh in a 30 day month, or 7.44kWh in a full 31 day month. At an average of $0.12/kWh, we’re talking about 89 cents per month. Yeah, 1% should save you money, but the maximum saved amount is 89 cents per month. I think the savings provided by lowering the level are negligible.
Your right, it very little it uses no matter what.
I was just wondering if it uses 10W nomatter the level it’s set to, or if it uses less power at reduced levels.
From a power dissipation standpoint, if it were to consume the same power while producing less light, it would mean more power would have to be dissipated as heat (to maintain the same power consumption), meaning they would become much hotter at lower levels than at full level, which would be a failure in their design. The answer is yes, they use less power at lower levels. Most likely not a linear function, meaning that 1% level does not mean 1% power (there is a power overhead for all the electronics in it, so think of it as a fixed residual power plus a variable power: P = fixed + func(level). I am totally going out on a limb here, the fixed part could be anywhere between 5 and 25 percent of the 10W, and that would cover power used by the Zigbee module, power loss in the power conversion from AC to DC (which has a variable part of its own), etc.
Thank you very much for the good points
So I have a few Osram bulbs that did work fine. They all stopped working when I added a new bulb. I reset the bulbs using the 3 second 5 times method. Now they are very hard to connect to STs - they take along time to connect and some times not at all. The one I can get to connect refused to answer to any on/off or any other commands.
I reset my hub by deleting my location but still the same problem.
The only issue I can see is that the bulbs only blink once when I reset them not 3 times as suggested they should.
Any one any ideas? (My samsung power outlet reconnected easily and works fine.
I thought I saw you were in the UK and I think that the single blink matches Osram’s European behavior. I’ve done a little messing around with their european stuff and what I’ve seen is that the single blink is their only confirmation that you’ve reset. You have to watch carefully to make sure that you don’t miss it. Once you confirm that the bulb has been reset, you should unplug it and set it aside.
Now you have to be careful how you add the bulbs back into your system. You need to start the add process on ST first. Next plug the bulb in and watch it carefully for the next ~15 seconds. It will flash once to show that it has joined. If it didn’t flash in that time, unplug it and plug it in again for 15 seconds and watch for the joining blink again.
In case you’re interested, the EU bulbs go into ZLL mode after 15 seconds and wait for the ZLL joining.
As far as the new bulb causing problems…I’m not sure what could have happened there, but maybe it’s a problem with that particular bulb? See if the problem keeps coming back as soon as you add that bulb back into the system.
Hope that helps.
great thank you.
I am in the UK yes.
I’ll give what you say a try.
I presume that we want them in ZHA mode not ZLL mode?
I tried what you said and it worked a treat. All lamps connected and working fine.
My next question would be what would be a good repeater for these bulbs? 2 are at the back of the house and at the moment the hub is in the middle of the kitchen not in my stair cupboard. I think I need a repeater for them.
I’ve read the osram bulbs themselves aren’t great repeaters as they drop data packets. Would a samsung power outlet do. Its not that I need a programmable outlet on the landing but I’ve a socket there that’s halfway between the back of the house at the hub.
Am I better with a power outlet or should I put the Osram spots in the ceiling along the hall (which I might do anyway).
Also how do you make the bulbs connect to the power outlet not the hub? Is there a good order to switch them on?
Zigbee devices will choose their own repeaters, that’s one of the strengths of the protocol. It’s based on a number of factors including signal strength. So generally they will choose the device that is closest to them as a repeater, whether that’s another bulb or a pocket socket.
To get devices to update their neighbor tables, after you’ve added new devices, you can just take the hub off of power (including removing batteries if it has them) and leave it off power while leaving all the other devices on power. Wait for about 15 minutes and the zigbee devices will go into “panic mode” because they can’t find the hub. Put the hub back on power, and each zigbee device will rebuild its own individual neighbor table. This process can take a while, so you might not see improvements until the next day, but it’s the surest way to make sure that each zigbee device is using the most efficient path to the hub.
In a typical residential setting in the US or UK You’ll need a repeating device about every 12 m. Remember that the signal is Omni directional, so sometimes the closest repeater is on the floor above or below. If you have brick walls, wire lathing or aluminum foil backed insulation inside the walls, or foil wallpaper, then signal may have difficulty getting through the walls which will reduce range. Sometimes it’s just a matter of trial and error experimentation.
Is there any smartapp design to work with Tunable white (not RGBW) lamps? For example some app which changes light color with a trigger or time?
I actually have the same need! A smart app that manage the color temperature would be great!
