Sengled RGBW LED Strip


#12

Looks neat! I'm guessing it's ZHA like their bulbs, which is certainly fine for Hubitat (assuming it doesn't repeat, also like the bulbs) but would prevent it from being able to join a Hue ZLL network (unless maybe it's Zigbee 3.0, which theoretically should work). The Quotra is the same price, and I've thought about getting one in the past as a cheaper alternative to Hue. I almost thought the same for Sengled, then I remembered which Zigbee profile the bulbs use (their website isn't helpful: it just says you need a "compatible Zigbee hub").

So, I guess if you want to use them via Hue, Quotra might still be the better option if you want something cheaper than the Lightstrip Plus. I wish I could see more pictures or specs, like how bulky their power adapters are or what sizes of extensions/splitters/adapters the strips may take, a weakness Hue has in that we need third-party or soldered solutions to make anything besides a (lit) extension work (some of which might work here if the six pins share the Hue spacing).

I use one large power supply to run a few of them.

And yeah...screw terminals!!

I received my Sengled RGBW LED strip today. Pretty nice package. I was able to pair it easily as a “Device”, then changed the driver to the “Generic Zigbee RGBW Light”. So far it seems to work fine.

@mike.maxwell, here is the fingerprint for this new Sengled RGBW LED Strip. Seems to work fine with the “Generic Zigbee RGBW Light” driver.


#16

I’d love to know if these strips are end devices or if they are capable of routing. Living with Xiaomi, one has to be careful. :wink:


#17

How are the colors and brightness? Do they seem to be bright enough to be "task" type lighting for under cabinets or just bright enough for accent or biased lighting?


#18

This is my first RGBW LED Strip. It contains alternating RGB and WHITE LEDs down the length of it.

The white LED's are definitely very bright. The only way the strip adjusts White Color Temperature is by adding in the color LEDs (i.e. adds blue for cooler white temps and red for warmer white temps.) At CT 2700, only the white LEDs are lit.

As for the quality of the Color LEDs... I really am not an expert whatsoever. I have never used Philips Hue, which seems like a benchmark most use to compare color quality and brightness. This Sengled LED strip seems fairly bright to me, and the colors that I choose using the Hubitat color picker in the device details page seem to be reproduced by the strip correctly.

The box list the strip as 1400 lumens.

The strip is fully encased in a clear rubber protective cover on one side, and has an adhesive strip on the other side. There are distinct points where the strip can be cut, but it might be a little difficult to solder on to the pads due to the clear rubber protective cover. The LED strip uses 5 conductors, labeled +24V, W, G, R, B.

Thanks Dan!

Hooked it up to my XBee and I can confirm that it is a zigbee endpoint.

I was looking for a controller for my bifrost and unfortunately these aren't going to work as they are only 4 channel - RGB and warm white. For cool white they turn on the white LED and the blue LED. the native CT for the white seems to be ~2700 - at least that is the temp where only the white LED is on - the blue turns on above that and the red below.

The par38 with built in motion works with Hubitat. Look for the "Sengled Element Classic" driver written by a user. You don't get the motion as a separate sensor but they still operate the bulb after sunset.

I have a pair on the front of my house that work just fine.

I finally got the chance to play around with one of these. It does warm white, around 2700K, very well. As Dan said, it adds in red or blue LEDs to make the color temperature warmer or cooler. To my eyes, it does not do this nearly as well as the Hue Lightstrip Plus. The warmest it can go doesn't look much warmer than the "default" warm to me, or at least the reddish/orange-ish hue is much weaker than I'd expect. Similar with the cools. They also seem to be brightest at 2700K and less so at lower or higher temps (for comparison, I think Hue is brightest around 4000K, which I also find to be a nice neutral white that isn't too cool but is better than a warm white for work areas like a kitchen).

So if you're hoping to use one of these to emulate Hue's default "Relax" scene (something like a bit under 2250K at about half brightness), you'll be disappointed--it will still be too "cool" of a warm white. I was able to get something similar enough by switching to color mode and finding a yellow-orange hue, so they're probably capable of doing this, as long as you don't want it too bright (which here I don't). Many colors aren't super bright or vivid, but it's not much different from the first couple generations of Hue bulbs there (the third and newer have a wide gamut and do most quite well, albeit not all at equal brightness).

That being said, they do cost significantly less. I've also played around with a bulb (the Plus) and noticed the same--brightest around 2700K, with the cools and and (especially) the warms not getting as cool or warm as intensely as I see with Hue. If you're happy with their bulbs, you'll likely be happy with the strip, too. I'm just much happier with how Hue handles shades of white. :slight_smile:


#23

Thanks for the feedback. Great to hear a comparison of the Hue versus Sengled products. Having never used Hue, I guess I don't know what I am missing. :wink: As you mentioned, the cost is definitely Sengled's big plus versus Hue, as well as the fact that Sengled can be directly paired to the Hubitat hub with no ill-effects on the Zigbee mesh network.

We don't use color much, except as warnings for alarm conditions in the house, like a water leak sensor being tripped, and a few other novelty automations.

Great write-up - Thanks!

New to hubitat, been up and running 2 weeks. Just got this as my first light strip. Set driver to generic rgbw, and I can control on, off and color through HE. However can it work with Google to control by voice like my other sengled color bulbs?

I told Ghome to sync devices after I got it running. But it won't show in the home app. Asking Ghome to turn it on or off just says"i can't do that yet". I have gone into home app on HE and ensured the strip is allowed.

Thanks for any advice.


#25

Did you add this new device to the Google Home app on your Hubitat Hub? Only devices that you allow Google to discover will be available.


#26

Yes I have.


#27

Scratch it, checked again after you said it. I added it and hit update, but forgot to hit done. Thx!!! Now working

I'm looking at just adding warm white (hoping for with defuser) to the underside of the kick plates in our kitchen. Sengled is $60 for me in Canada, but I don't need the color.

Trådfri is $20 CAD for the driver and $11.99 for a 31" strip with diffuser. So $31.99 for less than 1 meter.

Then there's this hacked controller.

I'm new to LED strips. Recommendations anyone? I don't care about color, but if it has it, that's fine too. I just want warm white. No cool white will ever go in my kitchen!


#29

I am looking at doing the same thing. I use the Sylvania Smart+ strips for under-cabinet lighting. They work pretty well and do a decent job with CT. Drawback is that they repeat. The Quotra strips on a Hue bridge are working well behind a TV and have about the same color and CTs as the Sylvania's. Being frugal and a Xiaomi user has led me to research the WiFi offerings. I'm looking now to see if anything can be used with @adamkempenich's MagicHome WiFi Devices.
I'd be interested to hear what you come up with.

If you want to flash custom firmware to an H801 device, which can be found here, and usethese strips, you could do it relatively cheaply. If all your cabinets are in a row (no breaks) it looks like you could do the whole kitchen for $50 or less.
(and yes, those are amazon Canada links :slight_smile: )

If you want diffusers you'd have to buy those separately, but if you're talking indirect lighting, they shouldn't be necessary, should they?


#31

Thank Ryan!

It's tiled floor. Not the nicest, but it's not going to get changed anytime soon. So it has a bit of sheen to it, and I don't want to have a bunch of dots reflecting on the floor. That's why I was thinking defusers would be needed. Maybe they aren't?

I've never done the firmware flashes on those device types. I don't have Android. Do I need it? This won't be something I'll be doing all the time. Would I need extra tools for a firmware upgrade?
Also, at $20 for the WiFi driver, the instructables hack with those strips you linked to might be an easier path for me.
