I used my AstroAI multimeter that also came with a K type temperature sensor. Interestingly enough set to 95c temperature was reading in the 70c+ degrees at the brew group and 80c in the steam boiler while my Bonavita control was also off by 10c degrees from the set 98c. I think these readings were inconclusive at best but i may have to invest into a better thermometer…
