Newbie questions: T-beam Critical error 8!

Hi cliff:

re: Joined: Unknown b094. What does this mean? What is it connecting to?
That means the node b094 joined the mesh. If you only have one device you now have a mesh with one member

re: what do the fault codes mean (a link is in this post):

"Critical Fault" printed on the screen

So for sometime we’ve been testing for various bits of busted hardware on boards. But we weren’t ever showing the user this information. Starting with the next device firmware release (in a couple of days?) there will be a new screen which will pop up if we think something is busted. If you see the following screen, you’ll be directed to this forum (where hopefully you’ll find this post). In this thread more experienced users/volunteers can help debug what is wrong (or hopefully you’ll find …

Do you have two devices? so you could confirm that without this check everything seems to talk okay.
