One of them is the \"Sonoff iFan03\". This is actually intended to control ceiling fans and a connected lamp via remote control and WLAN.<\/p>\n\n\n\n<p>Like many other Sonoff modules, the iFan03 module can be equipped with the free Tasmota firmware.<\/p>\n\n\n\n<p>How to program the Tasmota - or any other firmware - on the iFan03 is described in the following article.<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n<h2><span style=\"color: #ff0000;\">Safety instructions <\/span><\/h2>\r\n<p><span style=\"color: #ff0000;\">I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew &quot;better&quot; have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span><br \/><strong><em><a href=\"https:\/\/nerdiy.de\/en\/safety-instructions\/\"><span style=\"color: #ff0000;\">https:\/\/www.nerdiy.de\/sicherheitshinweise\/<\/span><\/a><\/em><\/strong><\/p>\r\n<h2>Affiliate links\/advertising links<\/h2>\r\n<p><em>The links to online shops listed here are so-called affiliate links.

process is described in the article <strong><em><a href=\"https:\/\/nerdiy.de\/en\/tasmota-firmware-flash\/\">Tasmota - Flash firmware<\/a><\/em><\/strong> described. <\/p>\n\n\n\n<p>If you want to flash a precompiled .bin file, you can also use the article <strong><em><a href=\"https:\/\/nerdiy.de\/en\/howto-esp8266-mit-dem-esptool-bin-dateien-unter-windows-flashen\/\" target=\"_blank\" rel=\"noreferrer noopener\">ESP8266 - Flash .bin files on Windows using Esptool<\/a><\/em><\/strong> orient<\/p>\n\n\n\n<p>Important: To switch your Sonoff module into programming mode you have to press and hold the white button while connecting the USB-serial converter to the computer. Then you can start the programming process.<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Set the appropriate template<\/h2>\n\n\n\n<p>Once you have flashed the Tasmota firmware to the module, you still have to configure the firmware as Sonoff iFan03.
