Hi I have quite a few of these and they all produce temperature plots that look like proper TBolts. I also have TBolts that don't read the sensor in high resolution mode. I have a couple TBolts with broken temperature sensor chips. Assuming the room temperature is varying several degrees C up and down over the time shown, those plots most closely resemble a TBolt with a blown chip.
