Reading a 100k thermistor with incompatible controller

[theloadedquestion]

Hey all,
So, I routinely push the limits of my leafbike 1500w with FF, running a YKZ7280-JA bluetooth controller, 80a batt, 230a phase (usually tuned down a bit to more like 60a batt, 180a phase, but sometimes not). While I try to be careful, and frequently test motor temperature by hand on the outside cover, and take breaks to cool down when needed, but this is obviously not the most reliable method and I'd sure like to be able to monitor in real time and with accuracy.

Unfortunately, my yuyangking controller does not appear to have any way to monitor motor temperature, only controller temerature (controller is big overkill for this motor and it never so much as rises in temp unless it's from direct sunlight). My leafbike motor does have the 100k ohm thermistor, so I figure there must be some way of just measuring it directly through a simple accessory device (short of stopping and using my multimeter every time I want to check). I know it is simply measuring resistance and comparing that to known values, but that didn't help me find any solutions, unfortunately.

Any ideas from those more experienced than I?
Thanks!
Curtis

On mine, I replaced the temp probe (was a KYT-183) with a 10K NTC so that I could use one of these inexpensive meters:

I wonder if such a thing exists for a 100k NTC? You may also benefit from something like Statorade if you aren't sing it already. At that point you could replace the temp probe with whatever you wanted if you open up the motor.

I would make sure to use a sensor compatible with CAv3

Okay thanks, I may end up having to go this route. Though I also may just end up waiting until I replace controller eventually and get a CA3 and replace the stock thermistor. Would be nice if it wasn't so involved but oh well.
