So I finally needed to subnet my home network. I have a lab and a bunch of other IOT things plus security system, etc. I had come to the point that all the broadcast traffic was severely slowing things down.
My HA system is running as a docker image on an Ubuntu server with a number of other images. I had it running just fine. It could find all my WEMO devices, my thermostats (RadioThermostat), my Samsung TV’s, etc. This was all on my 10.10.1.0 network. I have a Cisco 3825 ISR router with a 36 port switch plugin which I segmented into a 10.10.10.0/24, 10.10.20.0/24 and a couple others. The 10.10.20.0 is to replace the 10.10.1.0 network for all my desktops, servers and printers. I created a dhcp pool that excluded 1 to 100 on the 10.10.10.0/24 network. This meant the docker server with HA now moved to the 10.10.10.0 network. This worked fine until I fired up HA and all my configurations for dynamically addressed devices had disappeared. I tried rediscovering but to no avail. I use a Ubiquiti AP as my WIFI access point and I readdressed it. I could see the WEMO devices using the Ubiquiti management software and each had a new address in the 10.10.10.100 range but they couldn’t be discovered by HA.
I’m really at a loss as to how to bring this back. When I first started with HA it discovered the WEMO devices right off.
One other thing I find kind of frustrating with HA is there is no schema in the docks for the file structure. It’s kind of hard to see where you need to go without a road map.
Thanks for any help.
