  Hubitat allows development of custom drivers in Groovy. Its pretty easy to learn and the Hubitat framework allows connection and management of devices not supported by Hubitat officially like all your home-brew Arduino devices. You can also create custom applications to extend the capabilities of the devices. e.g Calculate dew point app:1153 2020-09-04 22:39:02.775 info Rho = 1.2405 kg/m3 app:1153 2020-09-04 22:39:02.771 info outsidetemp = 11.1 °C app:1153 2020-09-04 22:39:02.767 info Pressure = 100.8 Kpa app:1153 2020-09-04 22:39:02.763 info Absolute Humidity = 125.0 kg/m3 app:1153 2020-09-04 22:39:02.759 info Dew point temperature = 3.5 °C Still haven't finished the absolute Humidity calculation Credit to Bruce Ravenel for the original app code I based this on definition( name: "Calculate dew point", namespace: "hubitat", author: "Bruce Ravenel", description: "Calculate dew point", category: "Convenience"...
