I really like the ESP8266 for small one-offs, but I usually code for them with tons of abstraction, in something like NodeMCU or MicroPython. Because I can't justify learning the nitty-gritty of some proprietary 'Tensilica' core. Lately I've been meaning to look into using NRF24L01 transceivers for wireless communications in projects, since breakouts for them are less than $1 each and have the same footprint as an ESP-01 module.
