    Gosund SW1 switch firmware update

    Purchased a Gosund SW1 switch a couple of days ago. Priced right on Amazon $16.99 USD.

    I will be using this switch for the garage lighting. It will be triggered by two door sensors - IE: garage door and garage to house door.
    Last year installed LED bright lighting in the garage for daylight look. This garage has a 12 foot ceiling height which is a bit difficult to work in.

    Going to update this switch to Tasmota / Espurna firmware using Tuya-Convert 2.

    There are two Tasmota Templates mentioned over here ==>

    hxxps://templates.blakadder.com/gosund_SW1.html

    This switch would be using base Tasmota Bin with the template mentioned above.

    The alternative is to utilize Espurna firmware which is here ====>

    hxxps://github.com/xoseperez/espurna/releases/download/1.14.1/espurna-1.14.1-gosund-ws1.bin

    Here is a picture of the pre-installation hard ware configuration. I use an old computer power cable cut and connected to the switch.
