Is this a port of something from SmartThings? If so, a link to the original or some functional minimal example might help.
Off the top of my head, it looks like you're trying to retrieve a device (really com.hubitat.app.DeviceWrapper or possibly ChildDeviceWrapper) object from state. On Hubitat, you can't store a reference to an object in state, but I'm pretty sure it works the same way in SmartThings, so I'm not sure why that would work there, either. Or I could be misinterpreting something in your snippet. If not, you'll have to find another way to get a reference to the device object, say by doing a find() with some known piece (like Hubitat device ID) on a setting (from a user input) or getChildDevices() or however you either selected or created these devices in the first place.
Yeah, it looks like they are indeed trying to store a device in state. I don't think this worked on SmartThings, but it definitely doesn't work on Hubitat. You'd need to look at why they're doing that and how it could be worked around. I see there are also HTTP calls. On Hubitat, I'd recommend doing these as async calls instead (technically supported or at least in beta on SmartThings) unless you have a good reason not to, though either way would work. But these two things together might make this a bit more effort than your average port, so probably not a good place to start if you don't know Groovy and ST or Hubitat. I could definitely attempt to throw something together, but I don't have these devices and would not be useful for testing. I'd see if there are any existing community (or native) integrations that might do what you want first.
