Pressure BMP180 <995 hPa not updated

[makuta77]

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

Any ideas about this situation? Today again pressure is below 995 hPa and sensor are not updating in Domoticz...
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

Ok, I let you know when the preassure will go down below 995
Thanks for Your help!

Hi, nothing changed. Currently I updated to #4439 and i have the same situation: If preasurre <995 hPa Temp+Hum+Baro sensor stop updating.

Sorry, it was connection problem. Now it seems to work.
I will observe it closer. Thanks for your help!
