Hi @youxiaojie

Yes, it detects the power mode automatically. It even supports mixing devices with different power modes.

1.if different type of sensors, 1822 18b20 18s20 in the same line, is it ok?

  1. 3 sensors in system, so It will initialize 3 instances from class and get temp then print it. the question is how do I which one represent which component? and if I remove one, how the program do? eg, I hope to show:points1:23C point2 25C point3 28C for 3 sensors, if the middle sensors is removed, I hope to show:points1:23C point2 NC point3 28C. could you give me some advice.

Yes, I believe that should work fine. Please let me know if you encounter any problems.
