How was this not a bug before?

[torarnv]

Not sure, perhaps it's a regression? Or perhaps most people use a locally connected tellstick and don't need the tellcore-net part which needs socat on the HA side. Or perhaps the people who use tellcore-net do it via hass.io where the images are perhaps slightly different, including socat through some other way?

[pvizeli]

That is what Hass.io does and never addded to official Dockerfiles because they run the daemon inside container of every installation.

[torarnv]

Right, I suspected something like that.

Since the tellcore-net feature (specifying a host) is part of the tellstick component socat should be installed so that everything works out of the box with the official HA docker images.
