Hi Wiki
You are right ! When I flash with a firmware that keeps the settings and directly after without blank I flash with ESP_Easy_mega20181101_hard_SONOFF_POW_R2_4M.bin (because for me it's sonoff pow r2!) So everything works! Weird! Thank you

Hi All I bought p2 pow r2 v1.0 of 30 11 2017 and I have trouble to flash. Either I do not have wifi AP, or no power failure possible because loss of settings or no consumption supervision! After many many tests, the best firmware that works for me is ESP_Easy_mega-20181110_test_ESP8266_4096_VCC.bin ...
