I’ve successfully put the NRF24L01 inside the power meters metal case. Wasn’t any bother to do, I just added an extension wire to the antenna of a length recommended by a website. Although other websites say this should not be done but so far its worked. Only half of the antenna extension is actually outside of the case which seems to be enough. These NRF24L01 modules have worked very well and I really like the instant connection compared to Bluetooth.
