Did some more testing with OMG v1.6.0.
With any esp32_platform later than espressif32@3.5.0 both the 433 MHz door sensor and Sonoff RM433 remote must be very close to the CC1101 antenna to be detected. The no response is shown on the serial monitor unless the device is less than about 1 foot away. Using esp32_platform expressif32@4.0.0 may have a little better detection range, but it’s still not good.
Don’t know what else I can try to help identify the source of the problem.
I found that adding
[com]
esp32_platform = espressif32@3.5.0
to my prod_env.ini file works without the need to modify platformio.ini.
