I see the problem, and it’s nothing that you’ve done.

The `EN` pin on the Notecarrier-AF was originally designed to power down the entire board. As you now know, you don’t want this behavior when you are trying to use `SleepySensor`.

If you are comfortable modifying the hardware, you can cut the trace between the `EN` pin and the button, [as discussed here](https://discuss.blues.com/t/card-attn-restarting-my-host-and-notecard-when-running-under-battery/507/13). If you have an exact-o-knife, it is a snap!

I’ll DM and see if I can’t help fix your hardware situation.

Cheers,  
Zak
