M5stack ATOM Lite: Button (binary_sensor) does not respond

ESPHome
1

Dear all,

I plan to read my smart meter via SML. Therefore, I bought an M5stack ATOM Lite (specs see here and pin assignment here) and implemented a first program (below) to test the device.

The code allows me to change the LED lights on GPIO 27 via the HA overview and this works fine, but for some reason I do not understand, the button on GPIO 39 does not respond to a press. When I press it, neither the state on the HA overview screen changes, no do I see any response in the log.
Note, I copied the relevant code from here and I assume it should work well from this tested example.

Did I do a stupid mistake below, or may I assume that the button is simply defective?

I use the following code

Thanks a lot for your assistance!

Try inverted: true like in the example.

Thanks!
I already had the inverted setting; it does not change the behaviour… Tried again, but no response in the logs at all. All other events are listed, but button presses are not appearing.

I received a new Atom where the button is working fine.
