### Changed
- upgraded MyESP library
- minor changes
## [1.5.5] 2019-03-07
### Fixed
- Support the latest ArduinoJson v6 and espressif8266 2.0.4 libraries (in PlatformIO do a `pio lib update` and `pio update`)

- EMS-OT OpenTherm connector
## [1.5.4] 2019-03-03
### Changed
- MQTT keep alive changed from 5 minutes to 1 minute
### Added
- Callback for OTA. This is used to disable EMS bus during a firmware OTA update, which caused problems with the latest ESP89266 core libraries
- Added rough estimate of WiFi signal strength to info page
- Added the build time & date to the info page (optional in platformio.ini)
## [1.5.3] 2019-02-22
### Changed
- Support for latest esp8266 arduino core version [2.5.0](https://github.com/esp8266/Arduino/releases/tag/2.5.0) and platform espressif8266 version 2.0.0
- Added board type to the info screen
### Added
- Improved MQTT LWT (Last Will Testament). Uses payload called 'online' and 'offline'. See https://github.com/proddy/EMS-ESP/issues/57
- Added ESP32 support to MyESP library
- Added Bosch Easy thermostat, Buderus Logamax U122
- Support for changing boiler wwtemp via MQTT (merge #58 from egrekov). thanks!
### Removed
- Custom MDNS support. Now handled much better in the new esp core under OTA
## [1.5.2] 2019-02-04
### Changed
- Change wifi settings using the `set wifi <ssid> <password>` command
### Added
- Added incoming MQTT "TOPIC_BOILER_WWACTIVATED" to set the warm water on/off. Payload is 1 or 0. See [issue](https://github.com/proddy/EMS-ESP/issues/46#issuecomment-460375689).
- Added the list of all MQTT topics to the README file
## [1.5.1] 2019-02-03
### Fixed
- issue with Serial monitoring conflicting with UART when both running
- Fixed typo with -D settings in the example platformio.ini
### Changed
- `thermostat temp` now except floats (e.g. 20.5). Some thermostats may round up or down if they use 0.5 intervals.
## [1.5.0] 2019-02-03
### Added
- Support for RC10 thermostat
- New command `set serial`
### Changed
- Improved Tx logic. Retries are more efficient and startup is faster and less error prone.
- "# Rx telegrams" and "# Tx telegrams" show number of successful Reads and Writes initiated by the user or automatically by the code. This makes it easy to see if the Tx is working.
- Some refactoring in preparation for the EMS+ support coming soon
### Removed
- Removed the `poll` and `tx` commands
- `DEBUG_SUPPORT`. Now controlled with the 'set serial' command
- removed MQTT and WIFI settings from my_config.h. These have to be set either within the application (using set) or hardcoded in platformio.ini You can now check in `my_config.h` without everyone seeing your passwords!
- TxCapable removed from `info`
## [1.4.1] 2019-01-29
### Added
- The led pin, dallas pin and both thermostat and boiler type IDs can be set with the application, and stored.
### Changed
- some minor improvements to autodetect
## [1.4.0] 2019-01-27
### Changed
- last will MQTT topic prefixed with a header like the rest of the topics
- All double and float numbers rendered to 2 decimal places (precision = 2)
- Default logging set to None when starting a telnet session
### Added
- Added support for external Dallas sensors (DS1822, DS18S20, DS18B20, DS1825). See readme
- Added UBAParametersMessage type to fetch boiler modulation min & max values
- Report shows system load average
## [1.3.2] 2019-01-23
### Fixed
- Handle thermostats that don't have builtin temperature sensors when showing current temperature (https://github.com/proddy/EMS-ESP/issues/18#issuecomment-451012963)
### Changed
- Improved way to identify if the EMS bus is connected
- Improved 'types' command to show more details
- Improved auto detect of thermostat types
### Added
- Some more devices like the Nefit Topline & RC310 thermostat recognition
- Added a check to see Tx is possible. See 'Tx Capable' under the 'info' screen
### Removed
- Removed `MY_BOILER_MODELID` from `my_config.h`. It's always hardcoded.

### Changed
- Custom settings (e.g set led) moved outside MyESP
- Moved all MQTT to my_config.h making it independent from Home Assistant

- Improved checking for duplicate sent Tx telegrams by comparing CRCs
- Removed distiquishing between noise on the line and corrupt telegrams (https://github.com/proddy/EMS-ESP/issues/24)
## [1.2.0] 2019-01-01
### Fixed
- Incorrect indenting in `climate.yaml` (thanks @mrfixit1)
- Improved support for slower WiFi connections
- Fixed issue with OTA not always giving back a completion response to platformio
- Fixed issue with repeating reads after a raw mode send
- Fixed handling of long integers (thanks @SpaceTeddy)
### Added

- added un tested supporting RC35 type of thermostats
- Try and discover and set Boiler and Thermostat types automatically
- Fetch UBATotalUptimeMessage from Boiler to get total working minutes
- Added check to see if bus is connected. Shown in stats page
- If no Wifi connection can be made, start up as a WiFi Access Point (AP)
- Report out service codes and water-flow [pull-request](https://github.com/proddy/EMS-ESP/pull/20/files). Thanks @Bonusbartus
### Changed
- Build option is called `DEBUG_SUPPORT` (was `USE_SERIAL`)
- Replaced old **ESPHelper** with my own **MyESP** library to handle Wifi, MQTT, MDNS and Telnet handlers. Supports asynchronous TCP and has smaller memory footprint. And moved to libs directory.
- Simplified LED error checking. If enabled (by default), solid means connected and flashing means error. Uses either an external pull-up or the onboard ESP8266 LED.
- Improved Telnet debugging which uses TelnetSpy to keep a buffer of previous output
- Optimized memory usage & heap conflicts, removing nasty things like strcpy, sprintf where possible
- Improved checking for tap water on/off (thanks @Bonusbartus)
### Removed
- Time and TimeLib's. Not used in code.
- Removed build option `MQTT_MAX_PACKAGE_SIZE` as not using the PubSubClient library any more
- Removed all of Espurna's pre-built firmwares and instructions to build. Keeping it simple.
## [1.1.1] 2018-12-23

### Added
- Created this CHANGELOG.md file!
- [Added support for the Nefit Easy thermostat, reading of temperature values only](https://github.com/proddy/EMS-ESP/issues/9) - note *read only* (big thanks @**kroon040** for lending me an Easy device)
- [Added support for RC35/Moduline 400](https://github.com/proddy/EMS-ESP/issues/14) - *read only*
- [New raw logging mode for logging](https://github.com/proddy/EMS-ESP/issues/11)
- [New 'r'command to send raw data to EMS](https://github.com/proddy/EMS-ESP/issues/11)
- [Added MQTT messages for hot water on and heating on](https://github.com/proddy/EMS-ESP/issues/10)
- Implemented FIFO circular buffer queue for up to 20 Tx messages (Q command to show queue)
- Toggle Tx transmission via telnet (use 'X' command)
- Show thermostat type in help stats (use 's' command)
- Show version is help stats (use '?' command)
### Changed
- Improved overall formatting of logging
- Include app name and version in telnet help
- Improved method to switch off hot tap water in Shower Alert
- Telnet P and M commands have changed
- Enabling Logging in telnet is now the 'l' command
- Logging is set back to None when telnet session closes
- Improved fetching of initial boiler values to post to MQTT at startup
- Improved handling and retrying of write/Tx commands
### Removed
- Hid access from telnet to the Experimental custom function command 'x'
- Tx and Rx stats have gone from the stats page, as they were pretty meaningless
- Removed NO_TX define in platformio and replaced with system parameter 'command X'
- Removed -DDEBUG option in build
- Removed wwtemp MQTT messages to set the boiler temp. You'll never miss it.
- Removed LEDs for Tx, Rx and Err. Too many flashing lights and it drains the current.
- Removed capturing of last Rx and Tx times
- Support for older RC20 thermostats
### Known Issues
- There's a nasty memory leek when in telnet's verbose mode with sending which causes the EMS to reset when running for a while.
