feat: Use wifi mac address to register 'unique' RF remote ID
feat: add file system format button to debug page
feat: Added link to spiffs file editor on debug page
feat: added basis filename check on update page
feat: Logging buffer as local short lived vars
feat: Config save and reset moved to looptask
feat: More robust wifi scan code
feat: Monitor heap largest block free
fix: a little more robust itho init check
fix: websocket disconnect during firmware update
fix: OTA hangs when serial debugging is enabled
fix: static IP config subnet and gateway value were switched

Security:
feat: Added basic authentication support (for web interface, HTML API, file editor)
feat: Username and password are configurable

MQTT:
feat: MQTT Last Will topic
fix: MQTT cleanup, do not subscribe to own published topcs (thanks to sjorsjuhmaniac)

CC1101:
feat: Add RFT AUTO CO2 join command
feat: CC1101 Message decoding redundancy
feat: Move sync bytes to a less strick check
feat: Optional CRC check in CC1101 lib, disabled for now
fix: some newer itho remotes (536-0150) were not working correctly

Project:
feat: update hardware design files
feat: added build instructions

Version 2.2-rc2

fix: rc1 still had an issue with the CC1101 module, now the issue is really resolved

Version 2.2-rc1

fix: beta10 had an issue with the CC1101 module, a recompile seems to have 'fixed' it
fix: typo in CC1101 lib

Version 2.2-beta10

Version 2.2-beta10

feat: display hum/temp values on webpage if sensor is present (#21)
feat: home assistant auto discovery implemented (#15)
feat: show itho speed val above slider on web page (#20)
feat: add file system format button to debug page
feat: update hardware design files
fix: a little more robust itho init check

Version 2.2-beta6

Version 2.2-beta6

changes compared to 2.2-beta:

• Feature: Username and password are configurable
• Feature: Added basic authentication support (for web interface, HTML API, file editor)
• Feature: Autodetect for itho temp/hum sensor added (for testing purposes, activate through web interface)
• Feature: added link to spiffs file editor on debug page
• Feature: issue #7 (Added MQTT last will topic)
• Feature: Failsave boot code always formats SPIFFS
• Feature: Itho start / fallback speed adjustable via web interface
• Improvement: move MQTT code to one function / task
• Improvement: update build instructions
• Bugfix: issue #12 (Failed MQTT connection causes WDT reset, WDT timer set to a value bigger than MQTT Connection timeout)
• Bugfix: Removed unnecessary wdt_init statements
• Bugfix: issue #11 (cannot connect to WiFi reliably with firmware v2.0.9 and higher)
• Bugfix: config could not be saved on HW rev 1
• Bugfix: Itho init on older devices showed failed status on cold boot
• Bugfix: Prevent crashes due to PubSubClient MQTT library memory issue

For hardware revision 2 there is also a 2.2-rftest.bin binary firmware version available. This version includes the updated CC1101 library for testing. The RFT AUTO CO2 remote (https://github.com/arjenhiemstra/ithowifi/raw/master/remotes/remote2.png) join command is not working yet. I would appreciate it very much if someone could test this remote (activate RF debug by: http://[IP or DNS]/api.html?debug=level3 ) and RF messages will appear on the debug page) and send me the debug output.

Version 2.1.1

Version 2.1.1

Bugfix: In some situations wifi wouldn't connect
Bugfix: Memory corruption caused by MQTT library

Version 2.2-beta

Version 2.2-beta

HW Rev 2:

• Spilt program in multiple tasks, this makes it easier to spot issues
• Stale tasks at least should result in a log entry
• Include reset reason in human readable format

All HW revs:

• Prevent memory corruption in MQTT PubSubClient lib (issue knolleary/pubsubclient#832)
• Switch to MQTT PubSubClient lib without dynamic memory allocation
• MQTT subscribed topic buffer max size
• MQTT Dynamic JSON to Static JSON buffer
• Logging buffer as local short lived vars
• Config save and reset moved to looptask
• More robust wifi scan code
• Monitor heap largest block free
• Added build instructions

This release contains much changes, especially for HW revision 2. Please test and report any issues. If this release is stable I will push it as stable release.

Version 2.1

Version 2.1

• IMPORTANT FIX: To prevent flash issues, don't store WiFi RF calibration data on flash. In some situations this may lead to flash wear out and stability issues (thanks TD-er!)
• FEATURE: itho speed is retained after reboot (not in case of config reset and file system format)
• FEATURE: File system usage info on debug page
• FEATURE: RF debug logging moved to debug page (will show up at first RF debug message)
• FEATURE: Improved handling of logging and memory use (moved const strings to flash)

Version 2.0.10

Version 2.0.10

• FEATURE: Simplified the ISR for CC1101 packet handling to setting one boolean to improve stability
• FEATURE: Moved all CC1101 related code to its own task
• FEATURE: Added a CC1101 task timeout logging to monitor possible CC1101 issues
• FEATURE: Small logging update (show CC1101 init status in the log)
• FEATURE: Added i2c bus busy timeout and logging if this happens
• FEATURE: AP mode now times out after 15 minutes after which the add-on reboots
• BUGFIX: Fixed newline bug and potential buffer overflow in logging code
