High(ish) power led dimming

ESPHome

hi all so i planing on running some led strips for lighting (24v 9.6w per m (i will be haveing about 35m)) and i was wondering if i could get some asistance in best way to acomplish this i am wanting as meany dimming steps as possable and right now i have 2 idea but i would like your opinion first on wich would be best

idea 1
straight use esp and mosfet(s) (and powersupply of cause)

idea 2
use a driver with 0-10v dimming and relay to turn off driver when not in use

this must not have any flicker even when verry dim

Both can work.
How many individual channels you want?
What about something like this:

That appears discontinued but they do appear to have a newer model with power measurement.

Unless you REALLY want a project to learn more than you probably want to about electronics I would follow @Karosm advice.

it will just be a single channle and that device dose not provide enugh power for what i am doing as i would prefer to onaly have one device to controle and not multiple

You have given us no information on your existing experience with anything electronics related. This isn’t brain surgery or rocket science, but it also isn’t finger painting. There are many ways to get it to work-ish. There are many more to have it not work at all. There are probably several ways to do it well.

Mosfets are reasonably forgiving devices, but when they fail, they can fail spectacularly. Turning them on or off slowly is pretty easy. Doing it fast enough for flicker-free PWM is not child’s play and could end up in the spectacular failure mode, especially at the power level you need.

How’s your existing knowledge level on the differences in mosfets?
What about driver circuits for them?
What are the requirements you need for the control circuit?

You can probably cobble something together and it will probably work-ish for some amount of time. Is that good enough for who it is for?

Using a dimmer with 0-10V input changes what you need to provide. The microcontrollers generally don’t output 10V, so you need a circuit that can do that. Perhaps a linear amplifier (voltage multiplier) from a DAC output would work.

There are multiple design decisions that need to be made.

hi there so ye sorry about that was in a littel bit of a rush erlyer but i know a fair amount about eletronics i have mostly used n chanle fets not raily tuched p chanle fets i do know for 0-10v to work i will need a “middle man ic/logic” i am looking for reliability and long life i am wanting basic dimming and on off controle of the lights i know that swiching mosfets at high speed can get tricky hence why i ask wich one would be best option
but i was also thinking of triac based dimming but i not ask about that as esphome docs state its not stable yet and i have not found a single dimmer pre made able to support the power requierments
and i wanting it all on one controler due to bugeting as i know most dimmers and controlers can get pricy fast

Pro version can go up to 390W, costing like two normal ones though. Pro version comes with 5yr warranty and they are top quality, if that count anything.
If that doesn’t fit you, read carefully what @neel-m wrote and start experimenting with DIY setup. I have nothing specific to suggest for easy flicker-free setup.

This one seems to cover all your bases. 10A per channel on each of the 5 Analog channels (30A total) at a reasonable price.

They even have a DIY kit if you want to get your hands dirty and save some money.

I fully endorse @ShadowFist 's suggestion of quinled products.

Shelly are good too.
