How to obtain the saturated vapor or liquid temperature from the simscape component: Condenser-Evaporator (TL-2P) during simulation?

In order to control the superheat at the exit of my evaporator (I have modeled this by means of the simscape component: Condenser-Evaporator (TL-2P)) as part of my chiller, I use a simple controller. However, to determine my current superheat I need the output temperature of the evaporator, for which I can use a sensor, and I need the saturated vapor temperature. I know I can obtain this value after simulation via simlog, however, I have no idea how to obtain its current value to feed into my controller during simulation. Can anyone help me with this?

In the latest release (R2021a), the 2P domain in the foundation library contains a Saturation Property Sesnsor that would allow you to do this: https://www.mathworks.com/help/releases/R2021a/physmod/simscape/ref/saturationpropertiessensor2p.html

If you can upgrade to R2021a, this would be the best solution. Otherwise, please submit a service request here and ask them to direct the request to me. I can send you a custom block for earlier releases.
