Modbus RTU Serial Enabled/Disabled by Script

[EjvindHald]

I have tried 2 variants of the script, and both seem to work wrt. disable/enable. However, the polling continues.

Below please find the script where one variant is commented out.

value = event.getvalue()
log('Air Con polling script fired, value=' .. tostring(value))

webrequest = require('webrequest')
vars = {
  plugin = 'modbus',
  request = 'config-save',
  data = {
    enabled = value
  }
}

res, err = webrequest('general', 'plugin', vars)
log(res, err)

--------------

--value = event.getvalue()

--require('uci')
--require('json')

--function getvar()
--  return 'config-save'
--end

--function json.data()
--  return { enabled = value }
--end

--ngx = { sleep = os.sleep }
--dofile('/lib/genohm-scada/plugins/modbus/web.lua')
