Domoticz

I have virtual thermometer and need in LUA script set temperature value.
How to do it ?

- http://lmgtfy.com/?q=domoticz+lua+temperature+set+level
- click first hit
- search for "updatedevice" on that page

This site I have visited before but it did not help me:
script: /usr/share/domoticz/scripts/lua/script_device_topeni.lua
------------------------
pn = tonumber(otherdevices_svalues['Termostat_loznice_nastaveni'])
pt = tonumber(otherdevices_svalues['Termostat_loznice_teplota'])
if (pn < pt) then
os.execute('curl "http://192.168.1.180/setting?set_heat=0"')
end
if (pn > pt) then
os.execute('curl "http://192.168.1.180/setting?set_heat=1"')
end

commandArray = {}
commandArray['Termostat_loznice_teplota']='60|33.33|44.44'

return commandArray
-----------------------

First block run OK.
Termostat_podlaha_teplota still shows the temperature 0.....

Probably doing something wrong, my English skills are quite small ...sorry.

OK : commandArray['UpdateDevice']='60|33.33|44.44'

Thanks
