Bump.

Was given a sigma 16.12 with my caad 4 when I bought it in october. I recently put it on my bike and have ridden about 10 times with it. The cadence only works half the time and this last ride the speed only worked intermittently. I was searching for issues and came across this post.
I usually ride during the day so I don’t put my front light on my bike, this morning it was dark, so I had the light attached and on. Could this have been causing issues with the wireless sensors?
I checked the distance for the cadence and speed sensors and they were both good. It’s not telling me low battery but I guess that will be the next thing I check.
One other note the temperature when I started was 34 f. I don’t know if anybody has had similar issues.
Thanks
