    Fritzbox DECT adapter for ioBroker


    released version on npm with

     npm install iobroker.fritzdect

    or the actual version from github with

    npm install --production


    IP-address and password of Fritzbox should be defined via admin page, before the first start of the instance. The IP-address must be written with leading 'http://'

    The devices are detected automatically during startup of fritzdect instance. If devices are added to the fritzbox during a running adapter instance, then please restart the adapter for object creation.

    Several permissions have to be set in the fritzbox in order to interact with the adapter!

    A german explanatory doc is available here: install_de

    The widget requires that also vis-metro and vis-jqui-mfd are installed

    Common Issues / Frequently Asked Questions

    1. Fritzbox returned '00000000' no login possible. possible reasons:

      The fritzbox allows only a limited number of logins in a timeframe. There are no appropriate user rights set in the fritzbox. There is a time elapsing in the fritzbox blocking the logins. A german doc is available here: troubleshooting

    2. using https would result in:

        { error: { [Error: self signed certificate] code: 'DEPTH_ZERO_SELF_SIGNED_CERT' }

      to overcome this, the option "rejectUnauthorized: false" is used in the https.request.


    Fritzbox AHA API

    The API of fritzbox has the following access:

    • sethkrtsoll
      • 8-28°C for automatic control
      • greater 28°C (254=ON)
      • greater 28°C (253=OFF)

    These settings are covered by the hkrmode and the 3 buttons. The activation lasts as long there is no other command or programmed sequence.

    Additionally there is the access to:

    • windowopenactiv
    • boostactive

    These are indications as well as commands (sethkrwindowopen,sethkrboost) and when commanded they act with the provided time limit (max. 24h). For activation of boost/windowopen the following sequence applies:

    • set the activetime to the desired value in minutes
    • activate the activ (from false -> true)
    • the acteendtime changes to the target For deactivation of boost/windowopen the following sequence applies:
    • deactivate the activ (from true -> false)
    • the acteendtime changes to unixtime=0

    fritzdect implementation

    From the above API possibilities the thermostat has different modes in point of view of iobroker.adapter:

    • auto (temperature control), to be set by hkrmode (0) or button "setmodeauto" -> the tsoll value will be used!
    • night if tsoll = absenk
    • comfort if tsoll = komfort
    • on (full open), to be set by hkrmode (1) or button "setmodeon"
    • off (full close), to be set by hkrmode (2) or button "setmodeoff"
    • boost (full open for limited time), detected by feedback boostactive, can be set by boostactive (false->true)
    • windowopen (full closed for defined time), detected by feedback windowopenactiv, can be set be windowopenactiv (false->true)
    • holiday (temp control), detected by holidayactive
    • summer (temp control), detected by summeractive

    ioBroker objects

    objects in italic are not part of all configurations objects in bold are datapoints from the adapter

    The datapoints are created on the basis of the returned values of the Fritz AHA API. All groups or devices start wirth "DECT_".

    API limitations

    • Boost and WindowOpen can only be set for the next 24h. time=0 is cancelling the command
    • updates to the thermostat are within a 15min range, depending on the previous communication of thermostat with fritzbox the next cycle is sooner or later, but definitely not imediately after an ioBroker intervention
    • if a windowopenactiv is set on a thermostat, which is part of a group, then the whole group and its thermostats is set to windowopenactiv (function inside the FB)
    • only a few color temperatures are accepted (mapped already be the API to valid ones)
    • only the predefined colors are valid combinations (getcolordefaults)
