Local connectivity thoughts #5

Was thinking wired, but for the same reason I like the sensors on battery, I really don't want to run a bunch of wires! So:

433MHz units? 2.4GHz NRF24L01 Wireless Transceivers?

Do I need to call out to Blynk first? Maybe I have a local master device (say on 192.168.0.123). When a remote ESP wakes up, it makes an HTTP POST/GET to 0.123, then hits up Blynk. The master device and wireless router will both be on battery backup. Should take some failure out of the equation.
