Send command to device using device ID

[user701]

Hi All,

I am new to Hubitat and I would like to turn off the virtual switch from the device code when a particular command is executed.

I did not subscribe to that virtual switch but I know the device ID of that switch. Is there a way where I can send an on() command to that virtual switch using its device ID?

something like, DeviceId.on()?

Regards,
Hardik

No, you need to have an input where you have the user select the device. The name of that input will then become the name of a field variable you can use to send commands to the device (or check its state, etc.).

See here for a recent post that describes app UIs in greater detail than anything else I'm aware of at the moment if you aren't familiar:

User App UI Documentation

Sorry for the state of the documentation. First of all, look at the Example Apps in our public repo: HubitatPublic/example-apps at master · hubitat/HubitatPublic · GitHub That will show you some of the basics. Here is a bit of a quick summary: Apps render pages. Within those pages there are means to get an input from a user, and means to present text and others items to the user. These are intermixed of course along with computations. Use what are called dynamic pages for the best control…

Otherwise, if you shared your code, someone can probably give more specific advice.
