Eccowit (GW1100) integration

Has anyone integrated with an Eccowit GW1100 gateway or collected data from the Ecowitt database via its API?

The Ecowitt has various sensors that you can plug in. I want to use their soil moisture sensors to determine when my watering system needs to run (as opposed to when it thinks that it should) and then use the Rachio plugin to run appropriate zone(s).
