access settings variables from lua

[koensch]

in the comfiguration page Setup > Settings a lot of parameters can be set by the user.

now i'm having a lua script and i am looking for a way to read a particular setting's value into a script variable to use it in a calculation.

i've been digging thru lots of wiki pages, but have not found where i was looking for.

question: can someone help me by showing where to find a sample or where this is documented?

You cannot do it directly in Lua or dzVents but you can use domoticz.openURL in dzVents or curl in Lua and call the api. You need admin rights to do that ( either by including a username/password in the url of a auser with admin rights or by allowing local network in settings to access domoticz without password)
Some of the settings are base64 encoded

You can find the api call on this Wiki page

in dzVents it could look like the samplescript below

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents enabled' is checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."
