Hello. I have a ep801 motor that is powered by Darfon 630wh and controlled by the Shimano ec 5003 display and the power button on the frame. I wanted to get Bluetooth connections so I bought the Sw en 600 L switch. It's impossible to get connected to ETubes and I get red battery and red switch in the compitability meny. Everything is updated. The funny thing is that I get connected using the stunlocker software and can adjust assist settings but the switch isn't working and no leds powering up. I tried the switch on a ep6 bike with no power button on the frame. Function was flawless. Anyone has a clue?
