v12.3.0

What's Changed 📦

DFRobot Edge101

This release adds support for the new "DFRobot Edge101" hardware.

ESPNow v2

The release also updates the ESPNow protocol for external displays from v1 -> v2. External projects connecting to BE will need to update to the v2 protocol off ESPNow to continue functioning

General fixes

The release also significantly improves Wifi strength on multi-AP installs, lots of fixes for BYD Vehicle, Nissan LEAF and Tesla batteries, and significantly improves the MQTT-HomeAutomation integration. Apart from all this, there are several other bugfixes and enhancements. Please check out the full list of changes below before updating

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 version > v10.0.0 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.
