Here's what to try next... locate your JayCommand Node in your basement. Notice in the upper left corner (see image) there are two wires for Awning#1 and two for Awning#2. The wires are quick connect... you can pull on the orange tab and the wire comes out.
Simply switch the two wires for #1 with #2 and see if the awning works as needed. If so, you can be assured the problem is the Node... good to know what caused the problem but sad to know it's around $900 for a Node... along with installation labor.
If this text works, I have the same issue as you. I've seen a few others on this forum have the same problem too. Some replaced the node, one person hard wired the awning and put a rocker switch on the wall (bypassing the node intirely). I installed a double-throw, double-pole switch to the four wires and I flip the switch one way or the other, same as the troubleshooting trick I described above.
I don't have a problem with $900+ for another node as long as I know it's a newer version of the node (notice in the photo, mine is 18A). Until I replace the node, the switch works.
So, give the wire switch a test and let us know what you find out.
Oh, take a photo of the wires attached before you do anything, this way you can refer to your photo to ensure the wires are back like they were before you changed them.
