Hi,
I have weather station with BMP180 and SHT21D sensors connected to Ceech Arduino board. It's presented in Domoticz (2.3530).
Today I found, that when the pressure was below 995 hPa sensor is not updating in Domoticz. When i delete it from devices list, it's even cannot be found. It's recognized as Unknown, General, Barometer.

When the pressure increase over 995 then sensor is recognized correctly (as TempHumBaro, Temp+Humidity+Baro, Weather Station) and it's updated.

So I thing that it is a bug.
Can someone have similar situation?
Best Regards

There is no limitation in domoticz,
the B<P180 can do 300-1100 hPa
Could it be limited in the mysensors sketch ?

I think you have to look in the Arduino/Ada-fruit library ?

well i tryied send fixed vaules in mysensor sketch. If P <995 all sensors are not update. When if P>995 sensors are updated.
This is my code:
gw.send(humidityMsg.set(SHT2x.GetHumidity(), 2)); // Send Humidity
gw.send(temperatureMsg.set(SHT2x.GetTemperature(), 2)); // Send Temperature
gw.send(pressureMsg.set(P, 1)); // Send Pressure

Thanks for the test, i found something here in the domoticz mysensors code (and bmp/netatmo)
There was a break line in the code that should not have been there.
Please try the new beta version #4388
