What's Changed 📦
This release adds support for Sono Motors batteries, Growatt LV inverters, and a ton of bugfixes. It is especially recommended for Volvo/Polestar users, since it contains some well needed improvements there. Be sure to read thru the release notes before installing this new version!
Note
Note, this version drops support for MCP2517 chips in favour of the MCP2518FD chips. This is to ensure proper CAN-FD timing requirements. By removing the hardware workarounds needed to keep a 2517 chip operating, we speed up the 2518FD operation. This change should not affect anyone, since no hardware designs have been made with 2517
Important
To take into use a 8.X.X version, Copy/Rename the USER_SECRETS.TEMPLATE.h file to USER_SECRETS.h and update connectivity settings inside this file. This is a new mandatory step to increase cybersecurity, to make it less likely for developers to commit sensitive credentials during software development
