Set Temperature using Lua

[thebeetleuk]

I want to set the temperature of a virtual device using something like...

commandArray['Temperature House'] = tostring(current)

.. which doesn't work. How can I do this without using the IDX?

[oeildefeu]

why without IDX ?

[thebeetleuk]

Because I want to define the dummy temperature device by name (as a variable), and don't want to have to specify the IDX as well.

anyone?

Think that this option can't be enabled at the moment in lua.

you have to use the idx format

[jvdz]

This is an example of a script that can retrieve the IDX for a devicename which you then can use to set an device with its IDX:

Code: Select all

commandArray = {}

-- Load necessary Lua libraries
http = require "socket.http";
JSON = require "JSON";
server_url="http://192.168.0.xx:8080"

-- Function to retrieve the IDX for a DeviceName
function GetDeviceIDX(DeviceName)
	-- get device IDX from Domotics
	local DeviceIDX,result,record
	DeviceIDX = 99999
	DeviceURL="type=devices&order=name&used=true"
	t = server_url.."/json.htm?" .. DeviceURL
	jresponse, status = http.request(t)
	decoded_response = JSON:decode(jresponse)
	result = decoded_response['result']
	for i = 1, #result do
		record = result[i]
		if record['Name'] == DeviceName then
			DeviceIDX=record['idx']
			break
		end
	end
	return DeviceIDX
end

DeviceName="ThermostaatHK"
DeviceIDX = GetDeviceIDX(DeviceName)
if DeviceIDX == 99999 then
	print("  DeviceName "..DeviceName.." not found.")
else
	print("  DeviceName "..DeviceName.."  DeviceIDX="..DeviceIDX)
end

return commandArray

The required libraries and how to install can be found in the DTGBOT wiki.
