Is there a way to have Hubitat recognize these devices or should I stick with the Resideo app which is currently cloud-based. I'm pretty technically saavy so if there is some API's or something that need to be exposed with a little elbow grease that isn't out of the question for me too... I thought I would reach out to see if someone has already did the discovery and implementation to make this work. Thanks in advance for any info!
It would take some work, but you could reuse the code for discovery, authorization, etc. and just create a new device for the leak detector. You would have to poll it, though, as events are not supported by the existing Honeywell Home App/driver. The REST API used by this App/driver is documented here: https://developer.honeywellhome.com/
