I habe been using my Edge 1040 solar with an electronic Shimano Dura Ace Di2 incl. Shimano Powermeter 9200 P. Connection of the sensors was easy and all the relevant performance values are displayed correctly during the rides (using the Force Vector Viewer-App).
The only problem: After having finished a ride (and having pushed the "save" button) all the performance values are saved/stored except the wattage values generated by the Shimano Powermeter. (Both Edge and Garmin Connect consistently show a performance of 0 watts). I have no idea what's going wrong. Could anybody help?
To be precise: wattage values are displayed during the ride, but not saved/stored afterwards. Average wattage is displayed as "0".
