Hi all,

Hoping to get some help/advise

I have a sharp tv which gets automatically detected by UPNP/DLNA-DMR when started, however it works the first time I restart my homeassistant without any issues.

BUT then if I switch off my tv, let it change to unavailable in homeassistant then switch my tv back on, it never works again just stays as unavailable?

I have checked the logs and it seems to show that the entity id already exists so I understand why It won’t add another entity but don’t understand why it won’t change the status of existing entity?

The other problem I have is I can’t setup manual DLNA-dmr in my config.xml file because from what I have checked/found out using a upnp client on my laptop,
every time the tv turns on, the upnp port changes? So I can’t set a static xml config in config.xml?

Is the anything I can do to fix this issue or am I stuck?
