Liste des devices

just pop this code into Test Luup code (Lua) (under UI5 APPS / Develop Apps):

local file = io.open("/www/devlist.txt", "w")
 file:write("[DeviceNo / id] device names on " .. os.date() .. "\n")
 for deviceNo,d in pairs(luup.devices) do
 if d.id ~= "" then
 file:write(string.format('[%03d / %s] %s \n', deviceNo, d.id, d.description))
 end
 end
file:close()

… then run it and go and look at the file it created with a web browser
