I am new to HA and trying to transfer from ISY to HA. I am running HA in a Proxmox VM. Everything is working well. Now I want to integrate my Insteon devices.
I have a 2413U PLM. HA sees the PLM as a USB to UART Bridge. I click Add Integration, select Insteon PLM and then Submit… it spins quite a while… then Unknown error occurred.
I would be grateful for and thoughts on what I can do to get this working.
