Spike not working with libre + Miao miao

I just installed spike, and it is connected to my miao miao, but in the sensor screen it shows basically nothing but ‘unknown’. It has not asked me for initial calibration. I use the libre 1 EU sensors, so they should be supported by spike? I know the sensor and miao miao can connect because they did on tomato before. Feeling kind of ■■■■ and like I won’t be able to get this loop going, like, ever. Please help.
