Domoticz

Can I operate a device by a simple url?

Something like:

http://mydom.co.uk:8000/device1

Thanks

When you mean to change a domoticz device then yes.
Look at the wiki for the api json: https://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s

I do mean operate a device, so for example if the device is a light switch then turn it on.

That's one of many items in the HTTP/JSON API link hereupper:
