Decimals missing esp8266 nodemcu, bmp180 en domoticz

I'm using an esp8266 nodemcu and bmp180 for de presure in domoticz, and missing some decimals.

For example the esp8266 log shows an pressure of 1013,51hPa, Domoticz hardware shows 1013 with steps of 1 hPa. Which setting I'm missing

maybe atmospheric pressure under 1 hPa is not really significant.
10 m water column = 1000 hPa
=> 1 cm water column = 1 hPa
=> 0,1 cm (1 mm) water column = 0.1 hPa -- is it really significant ?

It provides a streamlined graph rather than a blocky per 1hPa, thats why I now moved the bmp180 directly to the Pi instead of using it on the esp8266.
