@rhannink This looks good! I'm looking for a replacement of the Zipato Mini RFID tag reader I've been using the arm/disarm my Home Assistant alarm system. Unfortunately these are sold out everywhere. Your project sounds very interesting but at the location I'm planning to put this, there is no power... Would you think it would be possible to have the entire project (controller + RFID reader + screen) in deep sleep most of the time, and only wake it up when one of the physical buttons is pressed? Is there an estimate about how much power that would still use?
Thanks in advance for any reply!
