I would assume your electrical setup for the augers is the same as for the fans, which is a motor controller with momentary on/off buttons.  For my fans, I wired in these wifi relays to have remote control:  https://us.shelly.com/products/shelly-1-gen3

With this relay, I can turn fans on/off with my phone from anywhere.  The physical buttons on the fan still work like normal.  I can link these together, so if I turn one on/off, the others do the same.  I also have a script running on it that checks weather conditions and turns the fans on/off automatically for me.

Here is a picture of it in the box.  If you don't understand how the on/off buttons and contactors work in that box, if you are not comfortable adding wifi devices to your wireless network, or if your not into a DIY project, then this probably isn't a good solution for you.
