Is your RTD a Pt100? This does not work with the 1000 ohm Pt1000.

All are pt100 (sensor and board)

i realised that i power-on board with pt100 later than esp8266 or arduino it shows correct values.

Dunno what i made wrong.

Also i made discovery, after power-on whole thing up (incorrect values) than disconnect vin or gnd from max31865 board and connect again in the same places as before i got correct values.

Can you tell me what is going on?
