I used these https://www.aliexpress.com/item/5-pcs-LM393-Light-Sensor-Photosensitive-Sensitivity-light-Sensor-Module-For-Arduino-Smart-Car/1729424221.html

it looks like it is can't find the radio module. Check cables and pins numering

dodgy cable/pin maybe?

there are some projects using esp32 to monitor presence of BLE devices.

@alexsh1 how much did one module cost?

Did it work before on an Arduino board? If you haven't tried and you paid it very cheap it could also be a fake chinese clone that is either bad or not a really nrf24 chip

Personally I like the SHt31 sensors better for outdoor use. With my node I am in 5uA sleep current

I am not sure if the 3.3v output from raspberry is enough to power the nrf24

I found this https://github.com/oneyb/rpi-embed-dev/blob/master/install-mysensors-gateway-raspberry.yaml but I don't know how it can be implemented.

@alaskadiy I'd make a raspberry gateway with radio directly on the raspberry, much cleaner solution
