WiFiThermostat - Changelog

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.

0.1.2
