@sundberg84 I use the example code for all sensors. I am not sure about the mains power fluctuations, how would I check that?
@gohan I changed all the chargers when I first had problems, I hope the problem is elsewhere. I am using 5V 2.5A mini usb chargers
@manutremo I am using NRF24L01+, bought from the ebay link on connecting radio page
