Hi there!
I would like to replace a zigbee TRADFRI LED driver:
TRÅDFRI Treiber für Fernbedienung, smart grau, 30 W Jetzt wird die Benutzung von intelligenter Beleuchtung einfach für alle! Der Treiber ermöglicht das Anschließen integrierter Beleuchtung von IKEA – einschalten, ausschalten und dimmen, damit immer...
Specs are: 24V, 0-1.25A, max. 30W.
It is actually connected to 4 white dimmable LED-spots and should be replaced by any possible WiFi HomeAssistant integrated device, i.ex. an ESP controlled one (ESPhome or tasmota) or a sonoff device…
Has anyone an idea how get this done? I’m a total noob in electrics.
Any help would be highly appreciated!!

How long is a piece of string?
There are many many wifi led drivers. You can build your own, or use something out of the box like this H801 RGBW LED controller — ESPHome (just add esphome) or maybe something from Athom https://www.athom.tech/esphome
The products from quinled are good too https://quinled.info/
Is zigbee giving you problems?

Actually there are no RGBW Strings/Strips attached, but 4 of these white Spots:
MITTLED Spot, LED, dimmbar weiß Hier kommt die Gläsersammlung oder das Lieblingsgeschirr glänzend zur Geltung! Beleuchtung macht Küchen gemütlicher, Gesuchtes findet sich leichter. Einfach zu installieren, auch ohne Elektriker. Ein praktischer und...
Like this:
Isn’t it (electrically) different from the strips you supposed?

You’d have to tell us what technology they use. They are probably just leds controlled by pwm. In which case they’ll be just what you want.

Okay, so:
The driver supports DC wattage up to
30W with 24V (so up to an electric current of 1.25A)
Teardown of the LED spot shows for each (see pics):
2.2W / 24V / 91,6 mA / DC
28 white LEDs inside
3 diodes
4 resistors
With this:
4 LED strings containing
each of them 1 resistor and 7 LEDs
Following this teardown video:
I do not know if the spots are connected in series or parallely.
I hope this helps you helping me?
THANK YOU!

I’ll look at the video with sound later (can’t right now)
However can you tell me why you aren’t using zigbee? Seems to be a ready made solution.

THANK YOU!
Because of Zigbee, sure - look my other topic:
Hello everybody,
I am messing around with zigbee lights since years when they first came up. Used them with their proprietary controllers (TRADFRI, HUE, etc.) and later changed to HA (via ZHA) trying conbee and now SONOFF CC2652P including routers on every floor again using them all (OSRAM, HUE, TRADFRI, INNR, and many more).
Event though this sure is a challenge with 40-60 lights in a four-floored house including the difficulties coming up with separate WiFi setup, different other proprietar…

Fair enough. Glad my neighbours are a reasonable distance away.

Hi there, sorry I have been in bed ill for a couple of days.
I watched it now and it confirms what I thought. It is a simple, analog LED, which means there is no fancy stuff to change colour or colour temperature. It is simple one colour and dimmable. H801 RGBW LED controller — ESPHome
The dimming is done via PWM. This is ideally suited to the H801 I pointed out to you before H801 RGBW LED controller — ESPHome . They are cheap from Aliexpress and reliable and well made. Even though they labelled RGBWW you can put any colour on each output (as the above link points out). They handle 24v, so ideal.
I have done a low quality drawing here, and also include my own yaml for a similar setup where I am running a number of analog strips on some stairs.

Hey!
WOW - Thank you!!! How can I show my appreciation? This is a super help!!!
Btw: did you ever disassemble a hue lightstrip controller? Is it also 24v and as simple?

No never. And I probably wouldn’t as my ZigBee works
