I only have sensor: in my configuration.yaml one time. I’m not sure what else to do with this because it seems like it’s setup correctly. I restarted the HA server to make sure I had done it in the right order and got the same errors in my log file.
Are you using a Obihai phone, or one of their adaptor devices? I have an OBi1022 and an OBi1032. I changed the IP address to test with both, but am getting the same errors after restarting.
When I looked into pyobihai, I see that it looks for line status here: PI_FXS_1_Stats.xml. When I got to that url on my local device (ip/PI_FXS_1_Stats.xml), I get a requested URL not found error. So I’m wondering if this won’t work with the phones that I have.
