Combining RTL 433 and sensors e.g. PIR

1

I wanted to save an ESP32 (although relatively inexpensive still a cost as well additional power cables); so I needed to add the PIR to my ESP32 running an SX1278 from Ai Thinker. See the example extension in environments.ini. ; tested this and it is working.

[env:esp32doitv1-aithinker-r01-sx1278-hcsr501]
extends = env:esp32doitv1-aithinker-r01-sx1278
lib_deps =  ${env:esp32doitv1-aithinker-r01-sx1278.lib_deps}
            ${libraries.unifiedsensor}
build_flags =
  ${env:esp32doitv1-aithinker-r01-sx1278.build_flags}
  '-DZsensorHCSR501="HCSR501"'
  '-DHCSR501_GPIO=13'
