I want to use ESP8266 or ESP32 to dim these non-addressable 12V led lights. can I do it with WLED or ESPhome?
You can do it with either of them.

My only experience with WLED is a 30 led WS2818B 5V strip running directly off the ESP8266 chip.
what components do I need to setup?
I think you’ll need to do some soldering, since the ESP8266 IO pins cannot deliver the power necessary to drive your LED string.
For my RGB LED strips I do something like this on each channel. The single LED represents the whole string of LEDs. There’s a current limiting resistor to prevent a current surge while switching the MOSFET, and a pull-down resistor to hold the gate low unless you drive it high with the ESP8266.

I do have an ESP32 running Esphome to connect the Xiamoi Bluetooth thermometer to the home assistant.
Can you post actual images of the device?
I googled around and found this video
which of these ESP32 board I should buy
or WROOM ESP32 Wifi Based Microcontroller Development Board Nodemcu
and this 15A 400W D4184 MOSFET Trigger Switch Drive Module In Pakistan will work or not?
The 4-pin socket header is for testing with a single RGB LED that can be driven by the ESP8266; the LED strings are driven via the screw terminals.
I am stuck here
Clicking on adopt doesn’t do anything. I can access the esp32 on its page 192.xx.xx.xx
edited the code but when I tried to install it wirelessly
got this error

========================= [FAILED] Took 33.25 seconds =========================
Progress so far,
LED does turn on, if I connect the D19 pin on ESP32 to PWM/trigger pin on power mosfet. It doesn’t matter which firmware I have on esp32, tried to flash esphome onto esp32 and ended up with above error (previous post) and then I flashed wled which was flashed without any issue, but I can’t change the brightness from wled app/ web-interface.
this is driving me crazy.
no replies?
I think you also need to connect the ground wire to the mosfet board.
When I connect to ground(esp32) to ground(mosfet board), the LED turns off. it isn’t being controlled by a WLED brightness slider.
I am unable to properly install esphome on ESP32, it gets installed through esp webtool but when I try to upload any sketch the following error happens

After doing it with WLED, I have installed esphome on the second esp32 with the following code which includes other sensors too.
esphome:
name: esp-web-tools-esp32-xxxxx
platform: ESP32
board: esp32dev
# Enable logging
logger:
# Enable Home Assistant API

ota:

ssid: "ABC"
password: "xxxxxxxxxxxxxxxxx"
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Esp-Br-Node Fallback Hotspot"
password: "xxxxxxxxxxxxxxxx"
captive_portal:
sensor:
- platform: xiaomi_lywsd03mmc
mac_address: "xx:xx:xx:xx:xx"
bindkey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
temperature:

battery_level:

- platform: esp32_hall
name: "ESP32 Hall Sensor"
update_interval: 5s
# Example configuration entry
light:
- platform: status_led
name: "Switch state"
pin: GPIO2
Now I want to do what I did with wled,
- Turn on the light at sunrise
- Increase brightness gradually until midday
- Decrease brightness gradually until sunset
- Turn off the light at Sunset.
How should I do it?
Edit:
What should mention in brightness
I went through light integration but it I am more confused. Light - Home Assistant

To set this up with ESPhome…you need to set an output in the config along with the monochromatic setting:
esphome:
name: dim-led-test
friendly_name: Dim LED TEst
esp32:
board: esp32-c3-devkitm-1
# Enable logging
logger:
# Enable Home Assistant API
api:
ota:
- platform: esphome
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
output:
- platform: ledc
pin: 03
id: "out_1"
light:
- platform: monochromatic
name: "Test Light"
output: out_1
