v10.13.0

What's Changed 📦

This release contains several MQTT improvements. MQTT users especially should check out each PR listed below for more information. In particular for cell voltages display precision to be 3 in HA, BE device instance needs to be deleted from HA MQTT integration, and then BE needs to be rebooted, in order to be re-discovered with the new entity settings

This release also adds DTC reading and clearing for BYD Vehicles, which will help develop the integration further, and aid troubleshooting misbehaving BYD packs.

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.
