RCS TZ45HR thermostat & reading multiple sensors

Is anyone using an RCS TZ45HR thermostat and able to read temperatures into HA for the internal sensor as well as the two remote sensors? Or, at least the two remote sensors?

I have one TZ45HR in my Z-wave network and I’m able to see only the remote sensor connected to RS1. I’m interested in being able to read both RS1 and RS2.

I guess what is needed is an updated definitions file for this device? It has three temperature sensors (one internal, two external) as well as a humidity sensor, and it would be great to be able to pull all of that into HA.
