The new version is smaller and has a clear, easy-to-read display. The display can be oriented in all 4 directions. The smart head can be detached for better pairing with the gateway. Included 2xAA batteries are a plus. Improved open window detection system (an external sensor can be connected), but unfortunately a worse range compared to the previous version
