Our first (currently not public) Paraimpu application for Chumby smart object works like a charm!
For example it is already possible to connect in the system a Pachube stream to a Chumby, configuring that connection as always...
The following picture shows an outdoor temperature measured through a sensor connected to Pachube. The configured Paraimpu connection forwards data directly to the Chumby device after a mapping is applied.
We are working hard to publish an improved app to Chumby App Store soon and to add the related ready-to-use Chumby Actuator in the Paraimpu workspace palette.
