Hello,
I’m creating a project for my AC with a D1 Wemos board, I’m a curious amateur, who is using bits of what I find in the community and a little I’ve created with what I’m learning. The result is this Frankenstein below.
Currently I intend to control two temperature sensors, a voltage meter, an output and an analog input on my AC.
Board: D1 Wemos
Temp Sensor: DS18B20
Resistor: 4,7Kohm
Relay: Tongling JQC-3FF-S-Z
Voltage sensor: GBK Robotics
The program worked fine, including in the app, but I have a problem with the temperatures, that on the serial monitor they appear correctly and in the app they keep switching between the virtual input V5 and V6 on app, how can I express myself, one second the value of the sensor 01 appears on the virtual input of sensor 2 and vice versa as well.
Everything is connected properly, but I have doubts. I read it here and there but I still do not understand what went wrong.
Oh I’m not using Sensor 3 yet, but I’ll use it in the future.
Sorry for the english, i’m still learning.
Thanks for the help in advance!
