0-10v dimmer --> esp32 + HASS

ESPHome
1

I have a dimmer that outputs a 0-10v signal.

What do i need to read that with an esp32 as in resistor(s) and other components, the ledstring is a Digital RGBWW and want to control the light with an esp32.

step 1 = just turn on/off the ledstring + dimming depending on the 0-10v the dimmer sends (acting as a translator)

step 2 is that once that works, I will be using HASS to do more light effects

I think i need a voltage divider and a capicitor ? between the 0-10v in order to read correctly ?

Are you sure it outputs 0-10V ? Usually it’s control circuit that has to supply a variable voltage between 0-10V to control dimming level :wink:

Its more that i need to read “12” steps or less between 0 an 10v-ish so an simple ADC conversion with some level of accuracy should be enough.

i am more a bit in the woods about the hw needed … aka the circuit to connect between ESP and dimmer
