This addon for EVCC will provide the interface between the volvo API and EVCC. It supports the 2FA Auth flow and does not need a MQTT broker. This module is build as a dedicated EVCC module in contrast tot the Volvo2MQTT addon (That is native to Home assistant and does not want to support evcc). This addon is build to improve on the issues Volvo2MQTT has and is not willing to fix for EVCC. As a bonus we have added functionality and greatly enhanced security (Not exposing door unlock etc.. ).

Current State:

• V1.8.1 released in the main branch and running stable in production now for over 100 days (Linux host) - Weather Module addon available and guide is in the wiki

Features in current release module:

• ** Car status is auto detectable by EVCC
• ** Multi car / charger branch to support multiple volvo vehicles and chargers and still working with auto dectect. ( If you need this use the multiple car branch version 1.10.1)
• ** No Constant live poll Only poll when connected and charging. Update poll intervall based on connection and SOC (high interval when charging, low interval when connected but not charging, super low interval when not connected)
• ** Only pull data interresting for EVCC from API to increase security (Not exposing coordinates and door unlock to possible hackers)
• ** Request minimal Oauth scope in auth session to improve security (Token does not include unlock or coordinate permissions)
• ** Handle all credentials encrypted at all times
• ** Volvo4Evcc is using a super light weight web instance to host the JSON response meaning no MQTT or extra broker is needed.
• ** Reduction in 80% of API traffic VS Volvo2MQTT, Meaning less traffic to your car and battery drain
• ** Application is Multi threaded to increase flexability
• ** Auto application restarts and startup via crontab no matter if app is started allready
• Support for Volvo 2FA authentication
• Direct EVCC Yaml intergration
  **Improvement over Volvo2MQTT or comparison HA modules

Added Features:

• Weather forecast support to auto set the MINSOC charging value based on solar hours for the next 3 days so you dont have to update your plan manual. It will increase when low sun and decrease when sun forcasting is good. Always keeps a buffer for unforcasted sun.

If you have a version which is included in EVCC I am happy to test

Waiting for a working Volvo integration in EVCC since the current Volvo integration is currently broken due to Volvo changes to 2FA.

Thats something they won`t build, Andig allready said they are not going to do that due to the MFA needs to be catched (Which needs some major redesign of how evcc does this) , so your only way is to go via MQTT using a HA addon that is not build or support EVCC , hence you have a lot of security and poll issues, or you can use this module if you want that is build specifically for EVCC
