The power usage on the region I live is phase-phase 220V as a default for everything (not only heavy load). I understand that the Sonoff Basic/Mini works fine. Instead of neutral I put in there phase 2 with phase 1 at the normal Line input.
Does this works for the Sonoff Tx? I believe that would be the same since it supports 220V and for the electronic part it only takes in account the voltage per se and for the load the same.
Does anyone tried to that type of device this config?
