One of the few dual switch in the market that can be connected to existing curtain manual switches such as Norisys and at the same time to wifi for automation with Alexa providing full Alexa functionality. The motor auto calibrates and then Alexa Voice command can have blinds Open in percentage terms eg 30%, 70% etc. After returning 2 other brand switches finally got this feature running on Sonoff! Super cool. Blinds can now be automated to open on sunrise, close partially at sunset and completely close at given time. Dismissing Alexa alarm in morning can be automated to have the blinds open 50% for gentle sunlight waking up. Works great!

It didn’t matter for my application but a warning to anyone. The Dual R3 has two different power measurement chipsets depending on the PCB version. I purchased from in Jan 2025 and received a v1.x (I think 1.6) PCB with the older chip. It is also a bit more complicated to flash with your chosen firmware because it doesn’t support diy mode. Hardware is great, 2 external switch inputs, 2 outputs, status led’s and a button, all in a neat package. UPDATE: Seller communicated well when I highlighted the version discrepancy and offered a refund as a gesture. In most cases it doesn’t matter which version you receive unless power monitoring is your prime reason for purchasing.
