UPDATE Dec 23, 2020
The tease of Sonoff continues. Sonoff shared a video of the switch modes the DUALR3 supports:
On questions of us they already answered with a wiring diagram which shows you how to use the Sonoff DUALR3:
So appearantly the S1 and S2 connectors don’t need each other anymore (each switch connector is for each gang) and now works with high voltage instead of internal low voltage. This is a significant difference to the Sonoff MINI/MINIR2.
Original message Dec 21, 2020
Today, December 21st, Sonoff announced they will release their Sonoff DUALR3 soon. This device is a 2-gang multifunctional device and can be used as a motor driver for e.g. curtains, blinds, roller shutters and awnings. But it can also be used as a 1-way or 2-way light switching device. The possibilities are almost endless.
Quite a lot people asked for a 2-gang version of the Sonoff MINI and Sonoff seemed to have listened to their customers / community with the upcoming release of this product. The DUALR3 remained te power measurement / monitoring features of the DUALR2, added the switch connectivity feature of the MINIR2 and also has schrunk to about the size of a MINIR2. The only thing missing according to the community is the ability to add a second switch to be able to witch both gangs independently from each other with physical switces or seperate dry contact sensors. Let’s hope an improved version of the DUALR3 which has that feature will arrive in the future.
Below is the announcement of Sonoff on Facebook:
