Releases: thorrak/brewpi-esp8266
v15c-beta - S2 Only
This is a test firmware that uses the Arduino v2.0.11 framework to see if it resolves issues with the ESP32-S2 chips. Non-S2 firmware will not receive a v15c release if this works.
v15a - ESP32-S2 Bugfix
The v15 release of BrewPi-ESP uses the latest ESP32-Arduino framework - unfortunately - has a bug in the IIC implementation for the ESP32-S2. Since the S2 was intended to be used with an IIC LCD every character printed (or "printed" - the actual presence of a screen is irrelevant!) to the screen causes a delay which locked down the whole controller.
This release is specifically for the ESP32-S2, and changes nothing other than reverting to a version of the Arduino framework based on a prior version of ESP-IDF. This should dramatically speed up builds for the ESP32-S2, and is a recommended upgrade for all users of the controller.
v15 - ESP32, Bluetooth, and HTTP Interface Support
v15 BrewPi-ESP Firmware
This firmware contains a number of significant changes and enhancements, as compared to the previous wide release (v11):
- File system initialization enhancements
- Substantial refactoring and upgrades (e.g. JSON handling)
- Unified handling of Serial and WiFi output
- Add ability to add human-readable names to probes (Thanks @speshak)
- Swap SPIFFS for LittleFS for ESP8266 Builds
- Fix message displayed with temperature control is set to “OFF” (rather than IDLE)
- Added WiFi information command to get signal strength
- Add support for ESP32 and ESP32-S2 modules
- Add Bluetooth scanning support
- Add support for using Tilt Hydrometers as a temperature sensor
- Add support for using TPLink Kasa WiFi switches
- Add mandatory confirmation to firmware to prevent accidental EEPROM resets (“network scanner” bug)
- Add support for TFT LCD Displays on ESP32
- Add support for "extended settings" not traditionally part of the BrewPi firmware
- Added a new HTTP interface for quick sensor assignment & settings updates
- Adds ability to configure minimum delays for heating/cooling
Firmware Versions / Targeted Hardware
There are six separate versions of this firmware:
- esp32_wifi_tft - ESP32 firmware for TFT displays
- esp32_wifi_iic - ESP32 firmware for IIC displays
- esp8266_wifi - ESP8266 firmware for WiFi connections (see note below!)
- esp8266_serial - ESP8266 firmware for serial connections (see note below!)
- esp32_s2_wifi - ESP32-S2 firmware for wifi connections (S2 version of the similarly-named ESP8266 firmware)
- esp32_s2_serial - ESP32-S2 firmware for serial connections (S2 version of the similarly-named ESP8266 firmware)
The ESP32 firmware is intended to run on standard ESP32 chips. The ESP32-S2 firmware is intended to run on ESP32-S2 chips, such as the Lolin S2 Mini. Bluetooth sensors are only supported on the ESP32. TPLink Kasa WiFi Switches are only supported on ESP32 and ESP32-S2 WiFi firmware.
Note about future support
v15 will likely be the final official release of this firmware for the ESP8266 microcontroller. Although there may be future releases, it is highly recommended that the ESP32 be used for new builds, and existing users that want to use new, upcoming features should explore migrating to the ESP32-S2 which - in builds using Lolin's D1 Mini - has a pin-equivalent board available that may be a direct, drop-in replacement. For discussion as to why, please see this post.
Note about the project name
As a result of the migration away from the ESP8266, the project is also going to undergo a name change from BrewPi-ESP8266 to BrewPi-ESP.

v15 Beta 6 - Release Candidate
This is the latest release candidate for v15. There is only one change from beta5, which is the reversion of a change that I made awhile back in the hopes that it prevents a (potential) issue with switching off heating/cooling when the appropriate temperature is reached.
