As you know, most of the Sonoff products are not DIN rail mounted, which makes it difficult to put the Sonoff products into the switchboard. With the Sonoff DR - DIN Rail Tray, this will be much easier from now on!
Sonoff DR can work with most Sonoff products, including Sonoff Basic, Sonoff RF, Sonoff Pow, Sonoff TH10/16, Sonoff Dual, Sonoff G1.
