Works great for motorized blinds...
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!

Works nicely with multiway switching and home assistant
Works well for multiway switching where you cant just replace the switches with smart switches. Slightly too big to fit inside a ceiling rose so had to use a cowl and fit up inside the ceiling space. Integrates nicely with home assistant and as it two channel it can independently operate both our hallway lights from HA whilst also able to turn both on and off from wall switch. This will only work on 2.4ghz wifi so if you have band steering, you might see an issue. Do yourself a favour and make an IoT only wifi SSID and lock it to 2.4ghz if you can.

It does what i wanted
Don't get irritated when trying to set it up at 1st, it may fool you because it starts by asking how do you want to use it, for motoring or switching... etc. ALERT!!!! PLEASE NOTE: This device is NOT to be used with pumps or the likes that uses above 1A current used with either one of the channels, or in total for both. For resistance (lights) total is 10A. I needed this device to run alternative pumps on schedules. but i had to install relays for every pump as they draw high current.
