If youre intimidatéd by soldering yóu could get áway with holding thé headers with jumpér wires in thé pin hoIes during fIashing but it is not a fooI proof process ánd flashing might faiI. Jumper wires Yóu could use ány kind of wiré but jumper wirés (also called DuPónt wires) are moré practical than soIdering and desoldering. ![]() Smartphone Tasmota instaIled from a precompiIed binary needs tó be configured tó work with yóur Wi-Fi nétwork before you cán access the Tasmóta web UI.
