Just got my hands on my first ESP32 and are looking to reuse existing Dallas temp sensors.
My problem is that I cant get them detected, answer is [11:58:01][W][dallas.sensor:080]: Found no sensors!
I have 7 sensors connected in parallel and they only have two wires, I connect them to GND and digital pin IO13.
What can be the issue here?
Thanks

Possibly, the sensors are premade and only have two wires, brown and white, you mean to connect data port and +5V with a resistor could do it? Any guess on brown or white?
Weird, they should have 3 (VCC,GND and DATA). Got some link to the product and/or pictures?
Probably counterfeits?
That’s the parasite power mode I’m aware of
All my dallas 1-wire sensor feature Red (VCC), Black (GND) and Yellow (Data) wires
