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.

v12.0.0
What's Changed 📦
Version 12 is a new major release of the Battery-Emulator, with many enhancements and MQTT changes that might require attention when updating. Please familiarize yourself with the release notes carefully before OTA updating to this version.
-MQTT: reduced memory usage and improved reliability
This release significantly lowers the heap usage of the MQTT module, with the biggest gains on double and triple battery setups, and fixes a bug where batteries 2 and 3 reported battery 1's charged and discharged energy totals. Cell voltages and balancing states are now published every 60 seconds instead of every 5, combined into a single message, while all live values — power, current, battery voltage, SOC, and cell min/max/delta — continue to update at the normal publish interval. Availability on the /status topic is now published retained once on connect, following the standard last-will pattern.
Two changes affect existing setups. Battery 2 and 3 values have moved from suffixed keys on <name>/info (such as SOC_2) to their own topics, <name>/info_2 and <name>/info_3, using plain un-suffixed keys. The separate balancing_data* topics have been removed, with that data now included in spec_data* under the cell_balancing key, ensuring perfect sync with cell_voltages. Home Assistant autodiscovery users need to take no action, as entities migrate automatically; only manually configured MQTT sensors, Node-RED flows, and similar integrations need updating.
-Inverter Charge Taper 📉
This releases implements an optional, battery-integration-independent charge power taper based on scaled SOC: the allowed charge power is linearly reduced from full at (100% − band) down to 0 W at 100% scaled SOC, with an optional configurable floor (minimum charge power held through the tail of the band). Configurable via a new checkbox next to the existing low pass filter setting, with taper band (percent) and floor (W) fields shown only when enabled.
-Periodic BMS reset improvements
Periodic BMS reset can now be performed at either 24h (default), or a 48h interval. There are now also two optional guards, shown in the web UI only when the periodic reset is enabled. Why do we need the setting? It's observed that for example AZE0 likes to finish balancing. If BMS rebooted during balance, it won't restart. ZE1 can overbalance, so it may be wise to intrerrupt it daily. The user has to have a choice here to improve battery balancing operation
Apart from all this, there are several other bugfixes and enhancements. Please check out the full list of changes below

v11.0.0
What's Changed 📦
Version 11 is a new major release of the Battery-Emulator, with many wireless cybersecurity enhancements and MQTT changes that might require attention when updating. Please familiarize yourself with the release notes before OTA updating to this version.
-
This release brings us several cybersecurity improvements. From now on, when the Wi-Fi access point (AP) is running with the factory-default password (123456789), and no client connects to it, it is automatically disabled after 5 minutes (raising a corresponding event). If a custom AP password has been set, behavior is unchanged and the AP stays enabled indefinitely. Limiting the default-password AP to a short provisioning window mitigates the attack vector while keeping first-time setup and recovery access fully functional. The log window had Wi-Fi/AP passwords printed in cleartext, in the settings UI the Wi-Fi/AP/MQTT/HTTP-auth password fields rendered the stored value into their HTML value attribute making it possible for malicious actors to read them. This has changed so that these fields remain empty, and when submitting the form without any of these filled, they will not be changed.
-
Long-pressing the board BOOT/FLA button at runtime brings three new features useful for on-site work and troubleshooting: long-press 5 to 15s starts the AP if it's not on (perfect to restart the provisioning window introduced above); 15s to 30s will wipe the Wi-Fi client settings and reboot with AP on (useful when local network changes, or runs in trouble); long-press more than 30s will perform a full factory reset and reboot (a physical, UI-independent recovery of last resort). All actions are decided on button release, based on how long it was held. Color led blinks white at various speeeds to confirm the selected stage (slow-, mid-, and fast blink respectively).
-
MQTT possible breaking change
⚠️ From now on Battery Emulator always sets a hostname, which defaults tobattery-emulator-xxxx(the last two bytes of its MAC address lowercase). This value is used to identify the device on all the supported platforms: this will be the SSID of the AP, the broadcasted mDNS name, the identifier in the DHCP lease request, the value for "MQTT topic name", "Prefix for MQTT object ID," "HA device name", "HA device ID", and the host identifier in the syslog messages. Consequently, the "Customized MQTT topics" checkbox and its four dependent fields ("MQTT topic name", "Prefix for MQTT object ID," "HA device name", "HA device ID"), the "Access point name:" field were removed from the web interface. This counts as a breaking change: if you rely on MQTT for your automations related to Battery Emulator, prepare for the potential adjustments (tip: if you used the same value for the four custom MQTT topics, you'll likely get away easy by setting that as Hostname from now on). This not only makes long term usage more straightforward especially when multiple emulators are in use, but also significantly reduced flash space requirements. -
Display support (128x64 OLED) has been removed for "LilyGo T‐CAN485". This breaking change also frees up the GPIOs - but please don't be disappointed by this - support for ESPNow v2 is in the works, which has many more advantages for display usage: a plethora of full-color display types will be able to show data even from multiple nearby emulators, much more data (including individual cell voltages) in a customizable interactive form, in a safer manner without physical connection.
-
A new logging backend has been added: syslog. This self-contained solution introduces no new libraries, no new sink patterns: reuses the same engine that was already in for USB / web / SD logging thus it was very cheap to add. The big benefit here is that events happening in Battery Emulator can be logged independently from the system (even on a NAS which supports log receiving for free) making troubleshooting easier on long term.
Apart from all this, there are several other bugfixes and enhancements. Please check out the full list of changes below

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

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.

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 🤖
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

v10.11.0
What's Changed 📦
This release improves cybersecurity, by adding the possibility to lock the webserver behind an username/paassword. It also adds new features such as contactor control for BYD batteries, support for double-Tesla battery setups, and much more. It also starts the Diagnostic Trouble Code (DTC) refactoring project, which aims to offload DTC descriptions to the repository, instead of consuming precious flash storage space. This means the old flash limited ESP32 boards like LilyGo T-CAN485 will now benefit from the previously featuregated DTC descriptions in integrations such as BMW iX / PHEV. DTC information is read from the internet instead of from flash. Massive thanks to @malec1984 & @jonny5532 for the work!
