Welcome to EMWaver

EMWaver is a focused IR + Sub-GHz specialist. It does two things well, straight from your browser: capture and replay 433 MHz sub-GHz signals, and learn and replay infrared remotes.

Two workspaces

• Sub-GHz — capture, replay, and transmit on 433 MHz with the CC1101 radio, in both packet and raw modes.
• Infrared — learn, browse, and transmit IR remotes.

There is no script engine and no AI agent. The workspaces are purpose-built and hardcoded — you don't write code to use them.

The hardware

It runs on the EMWaver Air — an ESP32-S3 with a CC1101 radio and IR receiver + LEDs — or on any ESP32-S3 you flash with the firmware. The device dials an outbound secure WebSocket to emwaver.ai, and the browser is the control UI.
