Domoticz

Is it possible to just show the pressure while for themperature I have the DHT22 which is more accurate.

Depends on your config.

I assume your using Domoticz hardware support.

Why don't you remove the hardware support and create (virtual) pressure sensor only and run a script (perl or python) which updates the pressure sensor through json?

I have a BME280 which isn't natively supported and had to create a virtual temp-hum-baro sensor which now gets its values by a script automatically.

We have a BME280 on order to implement this sensor native. Could be end of the year before this is done.

it doesn't matter which sensor you use. Native support within Domoticz is fine, and easy to add supported sensors.
But when you spend some time to decode the python or perlscripts provided by AdaFruit its easy to implement your own sensors and create individual sensors to your needs.

I made it simple for myself to create only one virtual sensor (needed a device with temp, barometer and humidity) to update through a script. Which i can rewrite simply by pushing the values to seperate virtual sensors.
