Photoresistor to measue green LED intensity

ESPHome
1

Hi guys, i have a fireplace stove at home and attatched to it a control unit, so i can use wood instead of gas. The unit have a green led every 10 degrees (30° 40° and so on to 80°). I’d want to automate the temperature measurement in a non invasive way, because when it goes below 60° it uses gas and happens that when nobody is there to watch we forget to fuel it with more wood before it goes below 60.

I was thinking to use two photoresistors, one close to the 30° led to know if it is on, and one close to the 60 led to know the intensity of the light and know if it is on or off.

I found these on amazon
AMAZON IT

Is it possible to use them in esphome? Which platform should i use to check if they detect light (LED is on or off)? I read that i’d need a resistor (10K Ohm) to use it on a D1 Mini, where can i find a sort of wiring diagram for two or more photoresistor on a single board?

Thanks.

This method is used to read energy meters.

But the led when gets to the temperature stays fixed, it does not pulse.

The article references a blog posting about using photo resistors with Arduino. The circuits down there should directly work with ESPs.
