That would be a handy thing, I have a Celestron focus motor on my C925 but they did not include a temperature sensor in those and temperature changes are the most critical thing to refocus for with that scope, The ZWO documentation does not say it (Or did not when I bought mine for my ED72) but they do have one.
I thinks it’s one of the most cost effective solutions out there, and cloudy reviews are positive in the main, indicating high quality. I built an arduino focuser but got stuck at the housing/attaching stage. I’m looking forward to electronic focus. I’m going to opt for the kit with hand controller and temp sensor.
They’re a good bit of kit, gives me great focus every time.
FYI - you probably don’t need the additional temp sensor unless you have a specific use for it. The inbuilt temp sensors works fine in my opinion and is sensitive enough to identify even a small temp change
