Decided to augment the microchip cat feeder with a NodeMCU+Hall-Effect Sensor. So I can get a push notification when my cat eats.

@map re: cat location (your other topic w/ ble)
have you considered using the microchip to locate a cat ("touch points") or do you want to use only ble & triangulation?

@fihu yes. Unfortunately that would require huge high powered antenna for anything more than a few centimeter distance.
