v10.12.0

What's Changed 📦

This release adds support for running 2x CAN-FD interfaces at same time. This enabled triple CAN support on several hardware boards. Notably the Stark CMR can now be retrofitted with a MCP2518FD chip, to make it a 3-CAN board (and 2xFD interfaces at same time!) 🔋 🔋 🔋

This release also adds the first official stable version for the BEcom hardware 🤖

⚠️ This release also fixes critical bugs related to contactor control in triple battery setups, along with improving overall safety by now waiting until communication with battery has been established before engaging GPIO controlled contactors.

We also added a notification system inside the webserver, where users will be notified once a new version of Battery-Emulator is available.

There is also a new checkbox for extending the CAN inverter communication timeout. Some inverters (Like Sungrow and offgrid Deye), need a longer than 60 second timeout. If you encounter CAN_INVERTER_MISSING and you are sure communication works, you can now enable the new "Allow longer CAN timeout" option, which triples the timeout period

Apart from all this, there are several other bugfixes and enhancements. Please check out the full list of changes below

Taking this release into use ⚙️

Important

In order to OTA update to this version, you already need to be on a v10 release!

Note that v10 was a major new release of the Battery-Emulator software. The first time when taking a v10 version into use, you are required to perform an initial one time USB setup via this webpage! This is because we changed the flash frequencies, partitioning layouts and other under the hood changes to ensure longterm system stability. After any v10 has been installed via USB, following 10.X.X releases can be updated over the air.
