SensBench is a browser-based ESP32 simulator for builders and smart-home builders. Wire up sensors on a virtual breadboard, read the serial monitor and test Home Assistant and ESPHome ideas virtually before touching real hardware. The simulator is free. The site also sells Home Assistant kits and optional paid AI builds.

I kept burning time and parts testing ESP32 + Home Assistant setups on real hardware, so I built a free simulator to prototype in the browser first.
