KPA500 RF Power Monitor +

A compact plug-and-play display unit ($199) that connects to your Elecraft KPA500 via RS-232 and shows six real-time readings — Power, Voltage, Current, SWR, Temperature, and Band — on a crisp 256×64 OLED, updating 10 times per second.

It also has built-in WiFi, so you can monitor and control the amp (power on/off, operate/standby, band change) from any phone, tablet, or browser on your network at kpa500.local. Multiple devices can connect simultaneously. One-time WiFi setup, no app needed, and the OLED works independently even if WiFi is unavailable.
