Hi @bjcresswell,
I believe 0.0.17 is old enough that the update process is broken (if I remember correctly there was a service we were using that stopped working), so you’ll need to follow the Installing Companion instructions from our docs, to download the latest image and flash it onto the Raspberry Pi’s SD card.
You might also be interested in checking out our Companion 1.0 Beta, which is the replacement software we’ll be building on going forwards
