Looking for simple/clean Code example for sleep() external interrupt.



  • Hi

    Im starting to look into powering some nodes with battery.

    I have been looking for a minimalistic code example with external interrupt but I cant seem to find one that I feel confident to adapt to my own needs.

    I have a 2 switch node that works like a charm. The code is mainly (or was it completly) from this thread. 2 Reed switches 1 Arduino Nano

    I will use the code/node to log a doors state Open/closed, Locked/onlocked.

    I Would like for the node to sleep as "deep" as possible and when the state of either pin changes, run the code once (Check if the value on the door has change, if so send the data. Check if the value on the Lock has change, if so send the data.) then go back to deep sleep.

    Will a deep sleep power of the Transiver?

    Can anyone help me in the right direction?

        The MySensors Arduino library handles the wireless radio link and protocol
        between your home built sensors/actuators and HA controller of choice.
        The sensors forms a self healing radio network with optional repeaters. Each
        repeater and gateway builds a routing tables in EEPROM which keeps track of the
        network topology allowing messages to be routed to nodes.
