I second this! Would love to use this screen, particularly if the example renders like the 'gauge' could be included as a parameter rather than needing to draw it manually.

This would be an amazing addition for devices like temperature/humidity sensors!

Thanks for this, I bought a few of these ages ago but never got around to doing anything and was pleased to see all the hard work done. They are really nice and very very cheap, I assume they are surplus/rejected smartwatch displays.

Just wondering if there are any components/packages/examples for drawing a gauge on a display with ESPHome? I haven't done much with displays yet other than drawing text, and I'm sure it's a common thing for people to do.

I make gauges on it, but in PlatformIO and just read values from mqtt from HA. Thats simple ;)

Yeah I want to keep everything in ESPHome really. I'm just writing a component to draw a nice needle gauge from a sensor, based on the graph component.

Can u show ?

I'd like to see the needle guage drawing component also
