yes. I am paying close attention to this, and will consider all these perspective as and when we induct remote outlets in reef-pi, based on HAL. It will be awesome if you post any relevant r2r links in the corresponding issue: https://github.com/reef-pi/reef-pi/issues/642@Ranjib
Did you see the reference to the esp8266 sonoff devices and tasmota on the other thread?
I myself prefer hardwired reef-pi but the sonoff POW R2 would allow power monitoring for 18 dollars if you could somehow incorporate it easily..
