Well I failed at this today.  I removed the remote system the electrician had installed and made sure everything worked with just the push buttons.  I am unable to make the auger shut off with the Shelly device once I turn it on with it.  I have to press the Red stop button on the control box to shut it off.  I don't think there is anyway around this unless I install a two or three way switch so that I can decide which way I am going to send power to the contactor.  This is how my electrician wired my bin fans so it makes sense. I've ordered some three way switches that will be here in a few days so I'll address it then.
