A conditional execution system and scheduler. Pretty much a self-hosted IFTTT. There is (currently) no UI.

pipx install git+https://github.com/mikeshultz/dowhen.git

useradd dowhen
sudo -u dowhen bash
pipx install git+https://github.com/mikeshultz/dowhen.git

You may also want to configure a daemon. You can use the service file in this repo as a template.

# Service file location may be different depending on distro
curl -s https://raw.githubusercontent.com/mikeshultz/dowhen/master/ops/systemd/dowhen.service | sudo tee /usr/lib/systemd/system/dowhen-test.service

Create a configuration file at $HOME/.config/dowhen/dowhen.yaml with your triggers. An example config file is dowhen.yaml.example. Each trigger describes when to fire and what to do when it fires.

For instance, to turn on a WeMo switch on sunrise:

---
triggers:
  - when: 
      name: openweathermap.sunrise
      args:
        zip: 59801
    do:
      # Turn on plant lights
      - name: wemo.on
        args:
          mac: "30:23:DE:AD:BE:EF"

Then you can run the daemon:

dowhen daemon

"When" modules act as triggers. They will signal when a condition is met. For instance, it will indicate the current time, or certain weather conditions have occurred.

The datetime When module will trigger on times and dates.

• daily
• hourly
• minutely
• time(time_string)

The openweathermap When module triggers on weather-based data.

• sunrise(zip)
• sunset(zip)

"Do" modules perform actions. For example, the Wemo Do module would do things like turn on and off Wemo switches.

The wemo Do module performs actions on Belkin Wemo devices.

• on(mac)
• off(mac)
• toggle(mac)
