Here's our 5SE with modifications I've made since getting it for my wife for Christmas in 2019:
It's a home made Arduino Nano based controller with USB 3.0 to laptop, 12v power in, USB 3.0 hub, 3 channel dew heater, 2 temp sensor input (3rd channel heater power follows 1st or 2nd channel), ambient temp sensor, internal temp sensor, humidity sensor, 12v supply to scope, 7.2v supply to Canon T3i, focuser controller with bluetooth, and two 1" fans. Displays show voltage in and current; internal, ambient, and scope temps; humidity, dew point, and dew heater power. Displays can be turned on/off or dimmed.

Dew heater plans at: https://sourceforge....wcontrollerpro/
Plans are for separate devices but I crammed them into one project box and added a USB hub.
