Hi, I want to suggest you a product. Why you don’t consider to produce a smart wall switch, for example a touch panel for EU market. In Italy we have 503 box and we prefer to control our lights also by hands in many situations.
This device should be able to turn light on/off like a normal smart witch using a relay. And more important it should be also a diverter or a button to command relay or multi switch point.
If you will insert an enertgy monitor and the Alexa/Assistant compatibility it could be the smarter device for this year. I found it very interesting in kitchen or other ambients where people had a very strong bulb with high efficiency and they don’t want to replace it.
