dynamic variable name

[admin]

Like this, and make sure that v is defined before devices:

Code:

-- data get from webservice
v = {hum=1, tst='abc'}
log(v.hum, v.tst)

-- devices
devices = {
  {'9d', 'SENSOR', '8/4/5', v.hum},
  {'9e', 'COMMON', '8/4/6', v.tst}
}

-- print some data from v, based on data in devices
for k,k_items in pairs(devices) do
  -- log variable name
  log(k_items[4])
  -- log the data in variable with name k_items[4], for example the data in v.hum or v.tst (1 or abc)
end
