I guess since you say you don't want to setup a separate server, then this is out for you?
I marked it [AS-IS] because there were complaints it wasn't working for some people. But I and several others have no problem with it. It updates status almost instantly now on 2.2.4.x, and everything just works. But if running node.js on a Raspberry Pi or in a docker container as some have said they were able to get working, is not going to happen in your home, then unfortunately there just isn't a solution.
