First time build: temperature readings exceedingly high: any troubleshooting recommendations?

[Rory Burke]

Hi All,

I just fully built my heater-meter and was able to flash it today and boot it up. it connects to my wifi, however, all of the temperature readings are consistently high. The probe temperatures are sitting around 42-43 degrees and the thermistor is 431 degrees. I am happy to share any information I can and appreciate any troubleshooting recommendations!

Power supply: if relevant, while I'm testing it I'm still powering it from the USB 5V power supply on the Pi that is plugged into a wall outlet

Board: HeaterMeter 4.3.6 Kit w/ Alternate Regulator × 1 w/ thermocouple
thermocouple: Perfect Prime TL0500, K-Type Sensor probe (https://www.amazon.com/gp/product/B0142SKL0Y/?tag=tvwb-20)
T
temp probe (1/2/3): Maverick Genuine Replacement Food Probe 3 Ft for ET-73, ET-7 (https://www.amazon.com/gp/product/B004W8B3PC/?tag=tvwb-20)

I am an idiot. I am going to leave this post up in case anyone else has this issue... I didn't select the right probe and now it's working perfectly.

I just had to go to the config file and select the correct probes. now everything reads 70'!

Is your oki soldered correctly. Its supposed to be on the otherside?. Im not familiar with the alternative parts, so i guess its pins could be reversed.
