I recently updated my firmware of sonoff basic device to the latest ( ITA-GZ1-TL) and the device lost the most usefull capability for me.
Bebore the upgrade when the power source of the device goes OFF the output of the device also goes OFF and tells the app that output is OFF and then device is OFFLiNE .
After the firmware upgrade when the power source goes OFF the output goes OFF and the device goes OFFLINE but without telling the app that the output is OFF now .
That stops in my case many scenes that hass that device as triger for other actions.
Please sonoff fix this issue , it changed my setup from perfect setup to useless setup .
