Hi there,

I would like to assign an environment or context variable to the location in solar events mode.  
Having had no success with it myself so far, I need your help. Can anyone tell me if that is possible? An example would be nice.

Thanks

Hello ..

this can achieved by sending a command to Cronplus to create a dynamic schedule.  
With the use of a Function node you can pick up the environment variables (with the location information) and construct the `add` command for the cronplus schedule.

**Based on the example in the cronplus Help tab :**

```auto
let longitude = env.get("longitude") // or flow.get("longitude")
let latitude = env.get("latitude")

msg.payload = {
  "command": "add",
  "name": "alarm1",
  "expressionType": "solar",
  "solarType": "selected",
  "solarEvents": "civilDawn,sunrise,sunset",
  "location": `${longitude} ${latitude}`,
  "offset": "-60",
  "payloadType": "str",
  "payload": "In 60 mins, it will be a great time to take photographs",
  "limit": null
}

return msg;

```

**Example Flow**

```auto
