I have tasmotized Sonoff POW - I can read power consumption data from it no problem. But I would like to tell immediately (or within a second or two) when switch is turned on if there is load (= device plugged in) so I could pop up an alert if there is no device plugged in when switch is turned on.
Tasmotized Sonoffs report their state within pre-derminated period to MQTT broker, but I wouldn’t like to set reporting period down to 5 seconds which is the minimum value.
