How can I change device name in LUA

How can I change the name of the device in LUA? Is it possible at all?

[lonebaggie]

You can use a json call :-

[url]http://IPADDRESS:PORT/json.htm?type=command&param=renamedevice&idx=IDX&name=DEVICENAME[/url]

replace uppercase chars with params

You can call the Json from within LUA use 127.0.0.1 as IP address

Beware command&param may cause ¶ error see

Thanks. But... In browser is OK but in LUA not working I reordering indeed but still not working. Any ideas?

It probably would help to show your LUA script so we can see whether that is indeed correct or not.

If I set the switch action with link to json it doesn't work

Understood something doesn't work, but you need to provide more information when you want anybody to help.

I'm a beginner and I'm just trying to write a script. I started with an switch action for test. And it does not work.
I need a simple script to check if a device is available. If so, it changes its name to $newdevicename so it is invisible.


I would like to customize this script to change the device name

Code: Select all

commandArray = {}

ping_success=os.execute('ping -c1 192.168.0.113') --tablet
if ping_success then
print("tablet online")
  here link to json to change device name 
else
print("tablet offline")
    here link to json to change device name 
end

return commandArray

What should I put in the script to work?

try

HttpPart=("curl 'http://127.0.0.1:8080/json.htm?param=re ... mmand&idx=" .. IDX .. "&name=" .. DEVICENAME .. "' &")
os.execute(HttpPart)

Where the variable IDX is the switch id you want to change and variable DEVICENAME is the new name of the device

I fail to understand why one would want to rename a device to reflect a status. I would simply have a device and set it to On or Off depending on whether it's online or not.

I think it quite a neat idea by renaming the device $name you can make it disappear from the dashboard and then reappear when its available again.

I might use that to get round the 10 device limit on selector switches if i have 10 selector switches I can have 100 choices super selector and hide the 9 switches that have not been selected
