    This one was a bit harder to flash compared to the other Sonoff devices. Rx and Tx signals are not available at a connector so needed to be soldered to the chip. See: http://www.ablegen.de/itead4channel/ Is running Tasmota 4CH pro configuration now which seems to work.

    Thank you for your delivery. The goods arrived safely. The relay works seamlessly in all modes. See the YouTube video link. https://www.youtube.com/watch?v=grBZbTK_aeU&feature=youtu.be

    An sich ist das Gerät super, aber die Sendung wurde in eine eifache Plasitiktüte verpakt .So das bei den äusseren Relais Gehäuse ist geplatzt.
