Hey would someone be able to give me some insight on how the master/slave setup works for home assistant. I can not seem to get it to work right at all and documentation seems a bit lax. I tried to search as much as I could and ask on gitter but no one responded.
Right now I have my main setup working fine and am trying to add a few slaves to the setup. To start with some thing simple I have a separate raspberry pi 3 that I have setup as a bluetooth LE tracker. I have the install on the slave working, the tracker running and devices are showing up. I quit hass on the slave. I setup the slave.py file from https://home-assistant.io/developers/multiple_instances/ and added the device tracker to be loaded and set the ip, remote api password, and the port.
That is about as far as I can get it to work. When I run the python script it runs in terminal but no output, so I detach from the screen and check top and I can see the script running. The slave never communicates to the master from what I can tell and there is no web ui for the slave. I don’t think it is loading properly but the documentation on how to configure this is lacking. Does anyone have a master/slave setup I can see their config examples or know what I am missing/skipping? I know it is at least starting properly because if the master isn’t running the slave.py file fails saying it can’t locate the host, but nothing every shows up in the master.
Edit: https://github.com/home-assistant/home-assistant/issues/3990 Looks like this may be to blame right now.
