LUA script to add up user variable
Posted: Saturday 09 April 2022 18:10
I think I have a really easy question, but I am just to unfamiliar with LUA to get this to work.
Using the script below I want to have an action in to get the user variable "dryer_run_counter" (which I created as a Domoticz-variable) and add 1 to it (count up with one), but I just don't seem to be able to do so. Can someone help with this?
I tried the code "commandArray['Variable:' .. dryer_run_counter]=(tonumber(uservariables[dryer_run_counter]))+1" or "dryer_run_counter = dryer_run_counter+1" but I think I am getting the syntax wrong. Who can help me in getting the syntax right. I found quite some examples, but none of them include the commandArray-bit that Domoticz seems to be using...
