Uses Radiolib to enable a TI-CC1101 module as an ESPHome RF direct OOK remote receiver/transmitter.
The included yaml files include configuration examples for ESP8266 and ESP32 micro-controllers. You should start by enabling dump_raw and making sure noise isn't being received when no transmissions are occurring. Adjusting bandwidth, data-rate, and AGC parameters can help with creating an optimal receive setup. The example includes the ability to expose these as controls in ESPHome or HomeAssistant.
- More bandwidth will likely enable receiving more varying devices on the same frequency, but will increase noise and may decrease range.
The ESP32 example includes an example UDP dumper that can help with analyzing pulse data.
- Use rtl_433 on a host with the socat tool to decode pulses streamed to udp broadcast:
socat -u UDP4-RECV:5009 STDOUT | rtl_433 -r ook:-
- Transmit/Receive was verified to work with esp8266 and ESP-32 board.
- No longer an issue - Arduino platform now works great :-)...
I cannot currently get transmit to reliably work with the Arduiono platform on esp32. Some have gotten this to work by setting remote_transmit/receive setup ordering and several other workarounds and these at one point worked for me - but with the latest ESPhome releases I don't see them working (the older remote transmit module appears to me to always drive zero and not an open-drain output) Current suggestions: If you need to have both transmit and receive on ESP-32 platforms, use the esp-idf platform, if you need only receive, then you can use either platform. If you must have transmit and the arduiono platform - more work will likely be required (see the Radiolib code - you can put the RX data on GDO2 and keep the RX and TX pins seperate)
