So the pt100 is for the UMO+ Correct? Online it said it was not compatible with UMO. (as long as I order a longer cable)
I kept trying to remove the cable from the hot end, using the blunt end of a drill bit which fit nicely in the hole, and was able to get it out probably 5mm, then I tried to pull it out with a pair of pliers, but I kept bending the metal casing of the sensor, which seems to have damaged the wiring inside. Now it only works when I hold the wires in a certain position. I sent a few emails around to see who has the 1.5m long cable in stock, and I'm waiting for a response.
