Simulated Temperature Sensor That Works With New App?

I had a couple of simulated temperature sensors that I used in the old app to display rainfall totals. I have a webCoRE Piston that plugs in the values as temperatures. It worked perfectly in the Classic app but in the new app they won’t display. I just get “checking status” and if I click on the device I see incorrect values. I’m assuming the DTH will need to be modified to make it work with the new app but I don’t know where to start. For now I’m just sending a PUSH notification with each value as needed but I would prefer to have the virtual device so I can see these values in the app. Thanks.
