Proteus Motion Sensors

I have a location on my property where Zwave isn’t feasible from a distance perspective. I have done a little work with the Wemo motion sensors, which are a little flaky, but are not super constent when working with Smartthings. Wifi is the desired approach, but finding limited options from a product perspective. Proteus seems like a good fit, but have not found too much on integrating it… Looks like there are some options with webhooks, but was hoping someone has looked into more of a direct integration with their API, exploring what the community knows…?
