Hello
I've got a dimmer with temp control from you but there's no information on how to use it. Could you please explain? If it's just a thermistor between VCC and TEMP ping then please provide it's characteristics to read data with ADC.

Pretty brutal support here. I was able to reverse it out of this repo: https:/github.com/robotdyn-dimmer/rbdimmerThermalESP32
It looks like its an NTC thermistor with B constant of 3950 at 25C at 10kOhm. If you want to use it in ESPHome you could do it like this:
sensor:
# Read raw voltage from the pin
- platform: adc
pin: ${ntc_pin}
id: ntc_voltage
attenuation: 12db
update_interval: 5s
# Convert Voltage to Resistance
# Circuit: 3.3V -> 10k Resistor -> Pin -> NTC -> GND
- platform: resistance
id: ntc_resistance
sensor: ntc_voltage
configuration: DOWNSTREAM
resistor: 10kOhm
name: "NTC Resistance"
internal: true # Hide from Home Assistant if not needed
# Convert Resistance to Temperature (Steinhart-Hart / Beta)
- platform: ntc
sensor: ntc_resistance
name: "Measured Temperature"
id: current_temperature
calibration:
b_constant: 3950
reference_temperature: 25C
reference_resistance: 10kOhm
Anyone?
