How to get compressor speed and other HP parameters into data-feed

I’m new here. I have a heatmeter set up for my Chiltrix CX50 heatpump (I"m in California - this HP may not be the on market in Europe, idk.). I just started sharing data on the heatpumpmonitor pages, so far using only OpenEnergy supplied hardware for the metering. I really would like to get compressor speed and maybe some other HP parameters, integrated into my data feeds. I have no idea how to do this - can someone give some guidance? I assume I need some code to read the controler’s bus, and separate code to intregrate into the datafeeds…?

(not sure this is helpful, but I do have SmartLife app monitoring my HP, and that does show compressor speed and a couple other parameters…)
