	- Sensors_OneWire: ignore value 85°C if last value <80 or >90 (filter 85 as it is used as error code)
	- Sensors_OneWire: increase precision to 12 bit
	- Sensors_OneWire: float values in web interface and MQTT
	- Sensors: fix bug not publishing OneWire values when DHT sensor is disabled
	- WebIF - Heatcontrol: hide Heat Curve and DHT sensor if disabled
	
2023-03-07
	- Sensors_DHT: changed log levels
	- Sensors_DHT: add option to disable DHT sensor
	- Sensors_DHT: make more settings pre-compile configurable
	- Scheduler: use millis for 100ms/1s/1m each, not nested any more
	
2023-03-06
	- fixed bug in config_set.ino - sensor configuration items were only available when compiled as variant thermostat
	- fixed web interface - conf UI sensors and heat control
	- moved one wire pre compile config to settings.h

2023-02-17 - 2023-03-03
	- huge code review, many changes to improve stability
	- basic multilanguage support (pre-compile option)
		- all strings used in program moved to header files and stored in progmem
	- nearly all modules/features are now pre-compile configurable via settings.h and/or build flags
	- move sensors configuration out of thermostat configuration as it will also be used in other firmware variants
	- firmware variant HEATCONTROL code complete and well tested (currently only language version DE is fully implemented)
	- firmware variant THERMOSTAT taken over from WiFiThermostat but not yet finished
	- other firmware variants as "WiFiBlinds" (UART to MQTT bridge) not yet implemented
	
2023-02-17
	- update arduinoWebSockets-2.1.4 -> arduinoWebSockets-2.3.6
	##- update DHT-sensor-library-1.3.8 -> DHT-sensor-library-1.4.4
	##- update Adafruit_Sensor-1.1.1 -> Adafruit_Sensor-1.1.7 (previously unused? necessary for DHT-sensor-library-1.3.8) 
	##  --> reverted as often could not read DHT sensor with it. did not investigate why.
	- update ArduinoJson-6.13.0 -> ArduinoJson-6.20.1
	- update pubsubclient-2.7 -> pubsubclient-2.8
	- update Bounce2-2.52 -> Bounce2-2.71
	- building with ESP8266 Arduino Core v3.0.2 works now (but not tested much yet)
	- building with ESP8266 Arduino Core v3.1.1 works now (but not tested much yet)
	- FS: replaced deprecated SPIFFS with LittleFS
	- config: complete rework - now saves binary structs instead of overly complicated to maintain json files to file system
	- config: move secrets to its own struct, which is saved to "EEPROM" instead of file system to make extracting passwords much harder
	- config: improve XOR encryption of secrets
	
2023-02-01
	- started "universal" base firmware using code base of WiFiThermostat v0.7.1
	- merged with WiFiBlinds dev version (also initially starting from WiFiThermostat) which already had many improvements
	- make firmware variant configurable by pre-compile config switches
