M5Stack 433 MHz transmitter (U114) – control remote switches from Home Assistant (SYN115)

Got 433 MHz remote-controlled switches at home? With the transmitter, Home Assistant can control them directly, without the old remote or a separate bridge.

Good to know

The transmitter sends simple ASK/OOK signals. Devices with encrypted or rolling codes can't be controlled. With the 433 MHz receiver (U113) you can first read the codes from your existing remote.

Works with

• ESPHome (component remote_transmitter)
• 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.

Specifications

• Chip: SYN115, 433 MHz ASK/OOK
