WiFiThermostat/CHANGELOG.md

WiFiThermostat - Changelog

0.3.3

• DHT sensor reading - retry if failed (does not fix issue)
• improved temperature sensor timeout handling
• updated Adafruit DHT22 sensor lib to 1.3.7 - that seems to have finally fixed the sensor reading issue
• renamed "misc" to "scheduler" as it contains only timing/scheduling functions

0.3.2

• fixed/improved: HTTP authentication handling
• added: device hostname (announced via DHCP) can now be configured
• fixed: restart function on web interface
• added: show AP SSID + password on display for some seconds when AP mode is entered

0.3.1

• fixed (issue #1): LCD - outside temp - wrong alignment on 1.1 digit values
• added: configurable labels for inside and outside temperature ("I" and "O" in EN or "A" in DE)
• fixed (issue #2): when (new) configuration values are not yet saved, initial values from source code are overwritten with blanks (only for most important values, not for MQTT topics, servers, users etc)

0.3.0

• split "mode" to "mode" and "preset", changes in nearly all source files
• add In+Out Temperature display (without humidity) without toggling on LCD line 1
• add publish topic "presetName" and "presetHA", where presetHA returns "none" for default preset and the name for the rest
• add configuration for preset names, off-message, option for non toggling temp display (conf2 page)
• minor fixed in http api and Web-IF
• fixes/improvements in MQTT handling (subscribe to less topics than before using wildcard)
• restart function: when holding down MODE button for >4s, display shows "Restart?". Restart is executed when:
  • MODE button is keeped holding
  • MODE button is pressed/held again as long as the "Restarting?" message is displayed
• return to default operation mode when + or - button is pressed
• changed position of preset mode indicator - now in LCD line 2 after the set temp
• added "flame" symbol in LCD line 2, shown when the heating is active
• added connection symbol (also LCD line 2), depending on received MQTT HEARTBEAT messages
• added fullscreen messages for WiFi connect and MQTT connect
  • shows IP on startup and successful WiFi connection
  • shows AP mode notification and SSID on unsuccessful WiFi connection
  • shows to which MQTT broker we are connected if connecting was successful
• added halfscreen (line 2) notifications - used for displaying the full name of the preset when using the MODE button
• fixed http authentication

0.2.2

• Home Assistant direct support (setTemp and setMode topics, real name used in setMode, mode names are configurable)
• added MQTT connection message on LWT topic
• default MQTT_HEARTBEAT_MAXAGE 180000 (former 12000)
• updated PubSubClient to 2.7 (now included in src due to changed parameters)
• minor improvements at MQTT connecting
• added additional publish topic for PIR sensor (configurable)
• bugfixes

0.2.1

• added second reduction mode with different set temperature
• MQTT reconnect now tries again every 5 min after 10 fails, finally restarts MCU on 20 unsuccessful retries

0.2.0

• improved MQTT reconnection management with heartbeat and force-reconnect
• improved MQTT callback function
• improved overall stability
• added correction value for set point temperature
• added some defines for default values
• added http control api with token
• added mqttReconnect http call
• bugfixes
• some documentation

Important: for now compiled using Arduino 1.8.5 with ESP8266-Arduino core 2.4.0-rc2, as WiFi (re)connection does not work properly in release 2.4.0 (spent many hours on that)!!

0.1.3

• button handling now uses library r89m/PushButton.h
• added support for external PIR motion sensor, can be configured to enable display backlight on movement, pushes status to Domoticz and MQTT
• lots of code improvements
• removed unused libraries, added library overview in README.md, included only used libraries
• added some initial description text in README.md
• added heating switch device - send to domoticz/in
• improved MQTT reconnect behavior. Retry every 15s if 1-3 connnects failed and just every 5 min if more to avoid blocking.
