Thanks for that, completely missed it. I've tried plugging it in directly, non-directly (stacked on relay board) and even just using power and data lines using a bread board and it wouldn't work. Waited a while and stacked it again and now it's working. No idea what changed, pretty sure I did my last firmware update before this post.
@Luciano-S. said in OLED expansion doesn't display anything:

Thanks for the awesome replies. Having trouble tagging this as Resolved, interface not allowing me.

So I've finally brought out my OLED expansion from the initial kickstarter. I performed a firmware update on my Omega. Without the OLED expansion plugged in, I get errors in the command prompt and web admin tool that no expansion can be found. With it plugged in, I do not get these errors. However, neither the command tools nor the web interface will display anything on the screen. Do I just have a faulty display? Is there something I'm missing?

So I've been thinking about building a digital thermostat with my Omega. So far, I feel I'll need the relay expansion (for control to HVAC) and a digital thermometer (DS18B20 should work). I'd also like to use the OLED screen expansion that I already have for a display. I can stack this on top of the relay expansion but after that, the OLED expansion can't be stacked upon. The digital thermometer isn't an official expansion so I need some sort of access to the GPIO pins for it. Can this be done or will I have to ditch the OLED screen?
