Hi,
I have a pair of Sunsynk 5.5Kw inverters - currently no solar but will be soon. I am looking for a way to signal that power is down to my Sonof installation using a NO or NC signal to a Sonoff mini. I thought that it would be possible through the Gen Start (pins 7,8) on the master but they seem to be permanently closed regardless of settings and the combination of settings to make it work eludes me. Any suggestions?
Tx, Tony
