Yamaha RX-A870 looses connection to HA

Hi there!

a few weeks ago, Home Assistant started loosing the connection to my Yamaha RX-A870. I think, it started with the HA update to 0.115, but i am not quite sure.

Anyway, after a restart of Home Assistant, the receiver, wich is connected via the Yamaha integration, everything is fine, but a few minutes later HA doesn’t recognize the entity anymore.

In the logs, the following error is shown:

Logger: homeassistant.helpers.entity

Can someone figure out, what’s the issue?
