Post data from GivEnergy battery to Emoncms and schedule charging and discharging based on Octopus Agile tariff.
givenergy_run_read_only.py
A simple script to read and post data from a givenergy inverter and battery to emoncms.
givenergy_run_simple_schedule.py
As above but also reads in a charge/discharge schedule compiled using the agile_scheduler.py script.
agile_scheduler.py
A simple battery charge/discharge scheduling program based on Octopus Agile day ahead tariff forecast.
Redis required:
The schedule created by agile_scheduler.py is transfered to givenergy_run_simple_schedule.py via redis which is a dependency for these scripts.
agile_scheduler.py also accesses the battery state of charge via a redis key populated from givenergy_run_simple_schedule.py.
Redis dependencies are available on the standard OpenEnergyMonitor emonSD image.
1. Install givenergy-modbus library:
pip3 install givenergy-modbus
2. Clone repo git clone https://github.com/TrystanLea/givenergy_emoncms /opt/emoncms/modules/givenergy_emoncms
2. cd /opt/emoncms/modules/givenergy_emoncm then Copy example.config.ini and rename to config.ini. Configure emoncms apikey and givenergy inverter ip address.
3. Modify install.sh to run either givenergy_run_read_only.py or givenergy_run_simple_schedule.py as required.
4. Install background service script. Run ./install.sh.
Run agile_scheduler.py from cron at midnight every night:
crontab -e
