Common script does not work in the way I want

[admin]

Check if you have duplicate function somewhere else.

You don't have to specify the address manually, use event.dst instead. This way you can map a single event script to a tag instead of creating many event scripts with the same functionality.

Don't create JSON strings manually, use JSON library:

Code:

local payload = require('json').encode({
  groupAddress = add,
  value = {
    [ dptString ] = value
  }
})
