      How much battery life you expect with this modified boot-loader and code?

      I also have project for mini.
      The project have pads for battery, battery protection IC, LIPO charger USB for charging... battery voltage measurements....
      But the project is not released yet, because high temperature during charging.

      At all of the time 328p will be in sleep forever, when button is pressed interrupt is triggered and wake the 328p power ON the radio send info power OFF radio and go sleep forever.
      Only when battery level go below critical level. the radio stay OFF and only interrupt and sleep forever.

      I am almost ready with the drawings of the hardware, and next week start work on software... you can see the project in the openhardware.io i gonna upload it later tomorrow.

      Thanks for the ideas, i will modify the code to use LowPower lib and will cut the power to the radio module to increase battery live, when last massage is send the node will never power the radio module, will be only short interrupt and go again to sleep forever. This will give me power usage 20times more than self battery discharge. Which have to give me node uptime around 260days with coin cell battery.

      Yes but in this case the last massage will be the same like the previous, only the battery level will be below some predefined value. i don't like this. I will think how to solve this.

      Is exist something "last wish" in MySensors, when battery go below predefined level the device to send last massage to the GW and go sleep forever.
      The idea is the controller/application to have information about the device and to be known this device is dead and need battery change.

    • RE: 💬 Door, Window and Push-button Sensor

      Thanks for fast reply, actually 900nA is to big number and i prefer to use xxx_POWER_PIN to cut the power of the NRF module.
      I am building switch powered with CR2032 battery and i want to extend battery live as much as possible, for a switch is not needed to keep radio alive, i need it ON only when transmit signal

    • RE: 💬 Door, Window and Push-button Sensor

      What will happen if i cut the power OFF of the radio after each transmission? is it needed to be initialize again before next transmission?
