Bill,
i solved my issue although not sure how. When I stated to use the designer and SmartApps I loaded all devices. Once I removed them and added them back in smaller groups the issue is not present. I do see a new issue with “Three Axis Sensors” giving an error. I will upgrade the builder as suggested above and see if the issue still exists.
On another topic, Within the builder wouldn’t it be possible to query IDE for devices and capabilities and auto populate the variables?
regards,
Ron
