So composting has picked up again and we found, what we hope to be, a steady supply of wood chips, which will definitely help. The smell has certainly gone down, but still having problems with the temperature. We are also debating about collecting food waste over the winter to prevent freezing; the thought was that if we keep rotating the composter and adding both food and bulking it might stay warm enough not to freeze and might actually speed up our composting process. 

Has anyone else has issues with an in-vessel composter and temperature?
