SKRat PT1000 2 Wire Temp. issue

Hello. I have installed an PT1000 sensor on my Skrat board and setup in printer.cfg as sensor_type the pt1000. But Klipper says 1.7 degrees at room temperature. If I touched the sensor the temperature goes up but not correct. I had also dipped the max 31865 switches to the pt1000 2 wire configuration. Maybe someone has an idea what I do wrong. Thanks in advance

don't use the max31865. Use the normal thermistor port and just add the sensor type override

Thanks a lot for your advice. I will test it if I come back home at Thursday. But I hat also write it in the override section before. But I will see. Maybe the sensor is broken.
