I may have overlooked your reference to owning the Netatmo system. I can't make a compelling case to switch when you already have a working system, which I expect can integrate with Hubitat....?
If you are still interested, I actually maintain / develop the Community drivers for the EcoWitt system, having been developed by a previous Community member. I also own an EcoWitt weather station that reports outdoor temperature, humidity, air pressure, rain, wind speed / direction and UV. There are gateway devices that can simply be used to receive readings from the various sensors and send these up to EcoWitt's web site or Weather Underground for analysis, but can also send the same data to a nominated HTTP endpoint, which in our case is the HE hub, sent over the local network. The HE drivers interpret the data feed and record the readings in virtual devices, making them available for use in automations and display on HE dashboards. The EcoWitt gateway devices can also take the form of an LCD display for displaying the current weather conditions. On my gateway there is also a temperature and Humidity sensor to capture indoor conditions. I also have Soil Moisture sensors in some outdoor plant pots, and have ordered an air quality sensor for CO2 and PM2.5 readings. Other Community members have also used a Leaf Moisture sensor for automation of their smart lawn mower.
