How to add a value in a HTTP string ? (openURL)

[HFman]

I am using domoticz.openURL to send data to an ESP module.
This works fine.

Example : domoticz.openURL('http://192.168.1.185/control?cmd=PWM,2,200')

The last 200 i need to change depending on temperature.
How can i make a varaiable from this one ?
Tried serveral ways... but not succesfull so far....

domoticz.openURL(
{ url = "http://192.168.1.185/control?cmd=PWM,2," .. FAN,
method = "GET",
callback = "getLog" ,
