433MHz Lora with cheap sensors-outlets #8

Can i listen 433MHz RF (cheap 433mhz door - motion sensors) or send (cheap on-off switches - outlets) with TTGO or Heltec Lora ESP32? Because RF Receive/send Modules are really crappy..

If I recall correctly those modules just transmit 433 MHz wave without any modulation. You can (in theory) use the FSK modem in direct mode to receive that (see the FSKModem example), but I haven't tried it myself.
