Rob, I spoke with TST and they said that it's very unlikely that you will have more than one sensor not working as it should. 3 and more is basically proof that the issue is something other than a sensor issue. In this case, it’s most definitely a radio frequency interference. Their radio repeater should protect the system from this type of interference.

They went on to explain what might be causing this issue:

-Repeater is not installed.
-Repeater is not installed in the most optimal location for a particular RV Type/model.
-You may have a device inside your RV running in the same frequency causing interference.

In this case, they recommend you reaching out to their customer service team for troubleshooting. Depending on the run model of your 507-color display, they may have an updated software that can offer more interference protection when travelling through High Inference Zones.
