recently i reflash my ITEAD Slampher firmware to https://github.com/arendst/Sonoff-MQTT-OTA-Arduino
for some reason, when i sent mqtt OFF message to turn off the light,
the light is dimming but not completely shutdown
when i send ON message the light ok
Same issue here, have flashed two Slamphers now, one turns off completely the other leaves the LED bulb partially on. I bought both Slamphers on Ebay so assume one may have been a knock-off with different components… Did you ever resolve the issue?
same here for me , got one slampher that dont turn off the lump, just make it dim… there was a problem with key i think.
