Without configuration file, the MqttOwfs daemon can read DS2405, DS18S20, DS1920, DS2406, DS2407, DS2423, DS2450, DS1921, DS1822, DS2438, DS18B20, DS2408, DS2413, DS18B25, DS2401.

From v2.0

The topic is made up with the device identifier and the device reading folder :

  • DS2401 : value /IsPresent (Special folder, see Configuration page)
  • DS2405 : value /PIO
  • DS18S20 & DS1920 : value /temperature
  • DS2406 & DS2407 : values /PIO.A and /PIO.B
  • DS2423 : value /counters.A and /counters.B
  • DS2450 : value /PIO.A, /PIO.B, /PIO.C and /PIO.D
  • DS1921 : value /temperature
  • DS1822 : value /temperature
  • DS2438 : value /VDD, /humidity and /temperature
  • DS18B20 : value /temperature
  • DS2408 : value /PIO.BYTE
  • DS2413 : value /PIO.A and /PIO.B

Example

Without configuration a DS2438 send three topic

  1. /owfs/26.123456000000/VDD
  2. /owfs/26.123456000000/humidity
  3. /owfs/26.123456000000/temperature

To retrieve the old functioning for this device (before v2.0), you can add a new section in configuration file

[26.123456000000/VDD]
displayname = 26.123456000000

Before v2.0

The topic is made up only with the device identifier, the value is obtained by reading the folder :

  • DS2401 : value /IsPresent (Special folder, see Configuration page)
  • DS2405 : value /PIO
  • DS18S20 & DS1920 : value /temperature9
  • DS2406 & DS2407 : value /PIO.A
  • DS2423 : value /counters.A
  • DS2450 : value /PIO.A
  • DS1921 : value /temperature9
  • DS1822 : value /temperature9
  • DS2438 : value /VDD
  • DS18B20 : value /temperature9
  • DS2408 : value /PIO.BYTE
  • DS2413 : value /PIO.A
