Just upgraded to C-8 and my dashboard thermostat modes are not working

[kahn-hubitat]

I posted an updated driver here. For the non zwave cloud version.

[RELEASE] Beta 1 - version of Honeywell Home Thermostats (Lyric etc...)

The refreshHelper method invokes the sendEvent call to the device, but currently sends the raw array/list - which gets "stringified". Instead, it needs to output as JSON, which is what my updated line 634 does. If you change this line in the App as suggested, then invoke a refresh on the Device, it should update the attribute and the dashboard tile should start working.
