Python script to take solar data from a local Enphase Envoy and push it to the ChargeHQ API.
Created because ChargeHQ is unable to support Enphase nativley due to Enphase 3rd party access policy.

ChargeHQ specific information available from https://chargehq.net/kb/push-api

Known to work with version 7 Envoy firmware that forces use of a token and session cookie
If you have version 5 Envoy firmware then try chargehq_v5.py
Script grabs initial token file from Enphase using the credentials you supply in the config.ini file and caches it in the .ini file
Script will renew the token when it has less than 30 days before expiry
At the time of writing Enphase set token expiry to be twelve months

Uses the Envoy production.json data.
