Connect pvnode with EVCC

EVCC is an open-source charging controller for electric vehicles. pvnode is built in as a forecast source — EVCC uses the 15-minute forecast to schedule charging for periods with expected solar surplus.

Setup

1. Create a site. Create your site with all its PV strings once in pvnode and copy the site_id. Tilt, orientation, power and everything else is configured there from now on (Sites & Strings).
2. Get an API key at API keys.
3. Add it to EVCC. In the UI, site_id and apikey are all you need to get the forecast flowing. Alternatively, straight in evcc.yaml:

Code
tariffs:
  solar:
    - type: template
      template: pvnode-v2
      site_id: # site ID
      apikey: # pvnode API key
      forecast_days: 1 # optional, default: 1 (= today + tomorrow)
      interval: 24h    # optional, default: 24h

Further options

All remaining settings are documented by EVCC:
