I ordered a B1 bulb via Ali express to evaluate it for using it with Tasmota. Received the bulb, but it seems completely dead. Seller offered me a refund if I return it, hoever shipping cost will be more than the refunc, so this is not an option.
Is there anything which I might overlook ? Connected it to mains via a switch expected it to light up after toggling theswitch 3 times, but nothing. Also not visible as WIFI access point.
Are schematics of the B1 available ?
Are there any people with bad quality experiences related to the Sonoff products ?
