As we all know WiFi modules use quite a fair amount of go juice transmitting digital noise across the airwaves and the ESP based module on Carbon 2.0 is no exception.
Sitting there in a Zen like state contemplating life the universe and everything while idle it’s still chomping through a battery sapping ~60-70mA!
Luckily it’s simple to place the ESP into a blissful slumber while life continues in the outside world when it’s not needed. By doing this the go juice for the ESP drops into the micro amps which is a much better option for Lipo powered devices.
By also placing the STM on Carbon 2.0 into Deep Sleep it would still be in the micro amps so NETMF IoT battery powered devices are indeed an attractive option
Easy to write rules to avoid abuse of the system…set it so it only triggers once per day. Or only at specified time periods, if the dog is to be fed more than once per day. And at the same time make clear that any abuse of the system forfeits that week’s allowance entirely.
