# espos_power Deep-sleep duty cycle for battery devices: wake, publish, flush, sleep — without losing the way back in. ```sh idf.py add-dependency "signalk-espos/espos_power^0.7" ``` Part of [espOS](https://github.com/signalk-espOS/espOS), an ESP-IDF runtime for Signal K devices. The components are released in lockstep, so one version of `espos_power` works with the same version of every other. **Documentation:** [docs/power.md](https://github.com/signalk-espOS/espOS/blob/main/docs/power.md) **Examples:** * [`duty_cycle`](https://github.com/signalk-espOS/espOS/tree/main/components/espos_power/examples/duty_cycle) Built on the espOS tree as a git submodule, or installed from the registry; either way `REQUIRES espos_power` in a component's `CMakeLists.txt` resolves it. Apache-2.0. Issues and pull requests: [https://github.com/signalk-espOS/espOS/issues](https://github.com/signalk-espOS/espOS/issues).
