I honestly don’t see it as slow, or as a nuisance, but then again I have several around the house, some incorporated into commercial products like the Sonoff S20 outlets, which I control over MQTT with open source firmware. Where it relates to power consumption, I have sensors running in low-power mode powered by AA batteries that last me many months, since the ESP8266 only consumes 40 _micro_ amperes of power in deep sleep, and waking up every 5 minutes to read a sensor and pushing out a single data packet isn’t especially taxing on the batteries.
