Re: ESP8266 - BME280 Sensor Readings Wrong

I just started to play with my BME280 and also noticed that the temperature is different then my SHT21's.
I have two SHT21 next to the BME280. SHT21's showing exactly the same temp and hum. BME is showing little higher temp about ~0,8 degree C wgen it is powered with 3.3 volt.
When I power with 5 volt it is showing 1-2 degree C higher, so it is definitely heating itself.
I did my tests by power off the sensor for 30 minutes then power on and check data every minute and I saw that the temp was rising for every minute.
