SYSTEM METRICS DISPLAY / ESP32 APPLICATION
PeekESP
PeekESP brings remote system metrics to Android, dedicated ESP32 displays, desktop hosts, Raspberry Pi displays, and Home Assistant. Monitor CPU, memory, storage, temperature, uptime, and network throughput across your devices — without making the ESP32 the only way to use PeekESP.
About this project
About this project
Numbers for CPU, RAM, storage, temperature and throughput travel from an agent on a monitored host, through a Cloudflare Worker, to a TTGO T-Display that redraws them every few seconds with LVGL arcs and bars. The board only dials out, so the machine being watched can sit behind CGNAT; a pairing code shown on the screen ties device and agent together, with no account. The left button (GPIO 0) pages between up to six machines, a clock and a power screen, and reopens setup on a long hold; the right (GPIO 35) cycles backlight or standby. Flashing can use the committed 1.25 MB merged image; changing code needs Arduino IDE or PlatformIO. Only the T-Display has run on hardware, standby draws milliamps, and the free relay quota is counted in requests.
