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.
