M5Stack 433 MHz receiver (U113) – read remotes and wireless sensors (SYN513R)

Many cheap wireless gadgets talk on 433 MHz: remote-controlled switches, doorbells, door sensors and weather stations. With the receiver, Home Assistant can pick up their signals and use them in automations.

Good to know

The receiver handles simple ASK/OOK signals. Encrypted or rolling codes (like most garage doors and car locks) can't be used. If you also want to send signals, combine it with the 433 MHz transmitter (U114).

Works with

• ESPHome (component remote_receiver)
• Home Assistant via ESPHome
• All M5Stack controllers with a Grove port

You also need

A controller, for example the ATOM Lite or AtomS3 Lite. Grove cable included.
