Hi, sorry if question is stupid. I really like the overall remote low-power sensor thing and already kind of reproduced what you are trying to do here.

But, I find it difficult to advocate myself for continue to use NRF24L01 chip if there is ESP8266 and I can connect directly to anything using my WiFi network rather than custom-designed and custom-configured network based on NRF chips. What is the advantage of NRF chip copared to ESP?
