I haven't read all the posts but initially what I've read you're reporting the device isn't getting to the temperature you've set?
First thoughts
Make sure the coil your using has a solid mechanical connection. (not a compressed fit pre-built coil)
Make sure your 510 on the atty and on the device are clean
Make sure to let the device and atty sit for 10 - 15 min before locking resistance, where they are both at the same room temperature
Set Compensate to your actual room temperature. Google
If you cant get the vendor to give you the specific TCR try Steam Engine Wire Wizard | Steam Engine | free vaping calculators or one of @Quantum Mech suggestions, either should get you close unless you have been sent the wrong wire.
If the coil resistance or compensate temperature are set incorrectly, once you apply power to the coil the difference in the rise of Ohms that the device detects will be less if those variables are incorrect.
For example if I have a known good .08Ω Ni200 coil it will go to about .16Ω with power applied. But if I lock in the resistance at .11Ω as soon as I'm done building it when I apply power to it the resistance will only rise by about .05Ω so the device will think the resistance (temperature) has only increased slightly and reflect that in the temperature display. If I wait and set it at .08Ω the resistance will increase by about .08Ω so the device thinks the resistance (temperature) has increased much more and again will reflect that.
