This hardly justifies being its own post but I just needed a container for my photos on how to install Tasmota on Sonoff S26 R2 smart plugs. For a more extensive discussion about installing Tasmota onto smart plugs please see my post about the Ledvance plug. Contrary to the Ledvance plug, the Sonoff S26 R2 […]
