By looking at the error, I suspect the following.
1. Do you have the IoT Gateway plugin installed? if not install it.
2. If installed, can you make sure you installed 32-bit JRE as required by IoT Gateway.
Also, in the current release we need not use IoT Gateway to write back instead native connection should work. You can simply make sure those properties are updated in bounded properties of the asset in Thingworx and make sure the property is configured for write back as others.
Thanks for the reply.
IoT Gateway is well configured and running normally, but write failed, seems like the tag '.Screen_Control' doesn't exist.
And in your comment, no need to use the IoT Gateway?
I can only trigger the alert, however, it will not displayed in Sense Hat display.
I imported the extension from Manu app website.
