Plan for tomorrow evening.... Sous vide the whole controller box so I can access the Pi and ESP32 ports. Wax will melt at 55c, well inside operational temps for everything. I'm still seeing Pi reboots nearly instantly after power cycles. Between 20 seconds to 10 minutes of SSH activity before it drops connection, not repeatable, and it requires a full power cycle to come back online. Starlink is being powered off the bench supply so it's out of the equation.
