FHEM_Powerrouter

Custom module which reads data from https://mypowerrouter.com (nedap powerrouter) and provides them as readings in FHEM This module is intended to run within the FHEM-Software. Currently the following data is read and provided to FHEM:

  • Power to grid [Wh]
  • Power from grid [Wh]
  • Power produced by Solarpanel [Wh]
  • Power directly used [Wh]
  • Power to battery [Wh]
  • Overall power consumption [Wh]
  • Overall power production [Wh]
  • Current state of charge of battery (if available) [%]
  • timedrift in Minutes (to monitor the really bad "Realtime" Clock)

Dependencies:

  • apt-get install libcurl4-openssl-dev cpanminus curl
  • cpanm install WWW::Curl::Easy
  • cpanm install JSON

Usage:

  1. Copy module to <FHEM_ROOT>/FHEM

  2. add the following lines to your fhem.cfg

    define mypowerrouter powerrouter

    attr mypowerrouter login

    attr mypowerrouter pass

    attr mypowerrouter routerid

    attr mypowerrouter battery_update_interval <ival_in_minutes>

    attr mypowerrouter delay <delay_in_minutes>

  3. Adjust logging path in module ($POWERROUTER_TEMPFILE_FOLDER)

  4. force fhem to reload the .cfg

Data is retrieved from the website every hour. If battery_update_interval is defined battery values are retrieved by given interval (0 equals disabled)

have a look at the timedrift_minutes Reading. This indicates how off the powerrouter-clock is. If It's 0, set delay to 5. This will shedule the update to 5 minutes after a full hour. If it's 5, either correct the clock or set delay to 10.
