If it’s like this for everyone, then I’d suggest adding an option in the firmware for the NTC thermistor to manually adjust the offset. Something like NTC\_OFFSET in the config, within ±5 or ±10 degrees (not sure what the difference is for others). So there’d be a way to line up the readings, using the barometer’s temperature reading as the reference at room temperature.

Какой нибуть NTC\_OFFSET в конфиге. в пределах ±5 или ±10 градусов (не знаю какая разница у других). Чтоб была возможность выровнять показания, приняв данные температуры барометра за эталон при комнатной температуре.

You’re selling dryers after all… For example, I buy a 3D printer, turn it on, and when it’s cold it shows me a 4-degree difference between the bed and the hotend. My first thought is going to be: what the hell did I buy, and how do I fix it?

that’s why on our side, with our components, everything matches)
