I had a script to get the real values from the switches on my ESP8266. Unfortunately as of MEGA the json structure has changed with more deeper levels.
I cannot get it decoded.

I like to have the Value of the different Tasknumbers. Or if possible directly using the Taskname (Boven) and the the Value for Taskvalue with name "Switch".

Please help !

"TaskNumber":1,
"Type":"Switch input - Switch",
"TaskName":"Extra",
"TaskValues": [
{"ValueNumber":1,
"Name":"Switch",
"Value":0}]
},
{
"TaskNumber":2,
"Type":"Switch input - Switch",
"TaskName":"Boven",
"TaskValues": [
{"ValueNumber":1,
"Name":"Switch",
"Value":1}]
},

This script assumes the data is stored in file testjson.txt:

Code: Select all

json = (loadfile "/usr/local/share/lua/5.2/JSON.lua") ()
file = io.open("testjson.txt", "r")
datainp=file:read("*a")
file:close()
input = json:decode(datainp)
result_table = input['Sensors']
tc = #result_table
for i = 1, tc do
   print(result_table[i].TaskNumber)
   print(result_table[i].TaskName)
   for count in pairs(result_table[i].TaskValues) do
      print('  '..count .. " ValueNumber:".. result_table[i].TaskValues[count].ValueNumber .. " Name:".. result_table[i].TaskValues[count].Name .. " Value:".. result_table[i].TaskValues[count].Value)
   end
end

May like to note that Domoticz provides JSON.lua as well. It's in [domoticzhome]/scripts/lua
