Hi scttmtclf;
The sBitx DE does not have Power / SWR detection circuitry. It is not difficult to add this circuitry to the DE, and several people have already done this successfully.
Look at the message thread titled "swr_bridge.ino"? - There are 60+ messages discussing the process, with the most recent messages from Scott KE8KYP and Juan WP3DN including photos of their -SUCCESSFUL- implementations.
Perhaps the sBitx software should have some way of indicating that the Power / SWR detector circuitry is not available (when there's no response to I2C address 8) but the effort to add this detector to the DE is really not that great - especially if you have some Arduino experience.
