Attempting to add a Gen 2 alongside my Gen 1. I get stuck where I'm trying to add a device. Gen 2 has the 4th LED blinking, so it is on the network, and has connected with your server. In app, I've selected add a device, selected Gen 2, and it hangs on the next finding devices screen. I've reconnected it to my wifi 3 times, I've reset the Gen 2 wifi settings, I've reset the Gen 2 to factory settings. Still, it gets stuck here every time.
So, I've got my sprinkler wiring torn apart from the Gen 1. Lesson learned, get the new unit functioning before you start to disassemble the current install to connect the wires.
