Looks like the module we use for transmission connection (transmissionrpc) is no longer maintained. Seems there is a fork available now which is under active development (transmission-rpc.) I think all that needs to be done to switch out is update the import from transmissionrpc to transmission_rpc, as well as update documents on how to install. (pip install transmission-rpc instead of pip install transmissionrpc) Would be nice if a transmission user tested this out and sent a pull request if everything is working.
