[1.2.1] 2019-01-02

Fixed

• Only process broadcast messages if the offset (byte 4) is 0. (https://github.com/proddy/EMS-ESP-Boiler/issues/23)
• 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-Boiler/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 'dout' flashmode to platformio.ini so OTA works now when uploading to a Wemos D1 Pro's or any other board with larger flash's
• 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. 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

Removed

• Espurna build notes and ready made firmware

[1.1.0] 2018-12-22

Fixed

• Fixed handling of negative floating point values (like outdoor temp)
• Fixed handling of auto & manual mode on an RC30
• Fixed condition where all telegram types were processed, instead of only broadcasts or our own reads

Added

• Created this CHANGELOG.md file!
• Added support for the Nefit Easy thermostat, reading of temperature values only - note read only (big thanks @kroon040 for lending me an Easy device)
• Added support for RC35/Moduline 400 - read only
• New raw logging mode for logging
• New 'r'command to send raw data to EMS
• Added MQTT messages for hot water on and heating on
• 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.
