i use esphome, d1 mini, MAX6675 and sensor k type.
I get an error Got invalid value from MAX6675Sensor (0x7FFC).
I’ve been looking for a solution for a long time and I found the problem.
so I did a little research on possible problems and came to the following conclusion.
- error 0x7FFC appears if the sensor is not connected to the max6675
- if the problem is in connecting SCK, CS, SO to D1 mini, the result is 0.0 C
the picture shows the solution to my problem. cut off the original connectors and wired directly to the MAX6675
