Take note of the following GPIO pinout, which you need for a reference in ESPHome / Tasmota: The technical sheet for this chip is available here.
In order to flash this chip you need to ground a pin to GPIO0 as outlined in this wiki page. These switches use the TYWE2S chip which is an ESP8285 based chip making it compatible with Tasmota and ESPHome. Initially, I set out to flash it directly on the chip using an FTDI adapter but when opening it up, quickly realised that would be a big hassle. I quickly got one and decided to give it a go. These devices are so called 'Tuya' devices that work with a cloud service but can be easily flashed. Recently, Action started selling a big amount of LSC Smart Connect devices that are compatible with Google Home and Alexa. My quest on flashing custom firmwares and controlling budget switches sold at Action discount store continues! This means it is no longer possible to flash these using the tuya-convert method below because a new PSK has been implemented by Tuya. UPDATE: It seems that Action is now selling revisions of the LSC hardware with a newer Tuya firmware. Flashing them with tuya-convert is impossible with this chip, their might be a hardware UART but that is to be discovered. UPDATE: Devices sold by Action under the LSC brand are no longer being manufactured with Espressif's ESP chips but instead use WB2S. : It seems that Action is now selling revisions of the LSC hardware with a newer Tuya firmware.
