Wanted an excuse for a fun project, and this came to mind. I would always forget to scoop the litter on my days of the week, so I would set an alarm on my phone. That got old fast, so I had this idea.

The screen shows “Scoop Me” until you press the button, at which point I render the “All Clean” view and start a 24 hour alarm using the RTC chip integrated onto the T5-display board. I then set the ESP to deep sleep, to be awoken by either the button press, or the INT pin of the RTC- set off by the alarm. If the RTC alarm goes off, I render “Scoop Me”. The battery life has been great, a month so far without a charge.

I use NTP via wifi to correct the RTC clock every month. I use the time to render the top left corner’s last cleaned message. Originally, it used wifi on every wake up to get the time, but I wanted to optimize that power draw by relying on the RTC.

Of course a silly unnecessary thing, but it makes the chore feel less like a chore and more like a game.

A few folks suggested some ideas for it, such as using it for a reminder to water plants which would be cool. If anyone else has suggestions or ideas, I’m all ears!
