Examples to use LUA to change setting on the fly.

In this example, you can change the sensor sensibility according to time.

-- demo setting update on the fly
   

--Special fonction
function os.capture(cmd, raw)
  local f = assert(io.popen(cmd, 'r'))
  local s = assert(f:read('*a'))
  f:close()
  if raw then return s end
  s = string.gsub(s, '^%s+', '')
  s = string.gsub(s, '%s+$', '')
  s = string.gsub(s, '[\n\r]+', ' ')
  return s
end

function SendJsonWithReturn(url,json)
	local curl = "/usr/bin/curl"
	local cmd = curl .. ' -X PUT -d '..json..' '..url
	local vac = os.capture(cmd, true)
	return vac
end

function SendJson(url,json)
	local curl = "/usr/bin/curl"
	local cmd = curl .. ' -X PUT -d '..json..' '..url
	local vac = os.execute(cmd)
	if vac ~= true then
		print('Send JSON Error')
	end
end

-- Script here

commandArray={}

local heure = os.date("%H:%M")

if (heure == '13:43') then
    print('Setting sensor sensitivity to 5')
    SendJson('http://192.168.1.1:80/api/787EE274E/sensors/15/config','\'{"sensitivity":5}\'')
end

We can too use DZ-Event with domoticz.openURL() but I haven't see an advantage in this situation.
